+# scrcpy (v1.16)
+
+Aplikasi ini menyediakan tampilan dan kontrol perangkat Android yang terhubung pada USB (atau [melalui TCP/IP][article-tcpip]). Ini tidak membutuhkan akses _root_ apa pun. Ini bekerja pada _GNU/Linux_, _Windows_ and _macOS_.
+
+![screenshot](assets/screenshot-debian-600.jpg)
+
+Ini berfokus pada:
+
+  - **keringanan** (asli, hanya menampilkan layar perangkat)
+  - **kinerja** (30~60fps)
+  - **kualitas** (1920×1080 atau lebih)
+  - **latensi** rendah ([35~70ms][lowlatency])
+  - **waktu startup rendah** (~1 detik untuk menampilkan gambar pertama)
+  - **tidak mengganggu** (tidak ada yang terpasang di perangkat)
+
+
+[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
+
+
+## Persyaratan
+Perangkat Android membutuhkan setidaknya API 21 (Android 5.0).
+
+Pastikan Anda [mengaktifkan debugging adb][enable-adb] pada perangkat Anda.
+
+[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
+
+Di beberapa perangkat, Anda juga perlu mengaktifkan [opsi tambahan][control] untuk mengontrolnya menggunakan keyboard dan mouse.
+
+[control]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323

+Anda juga bisa [membangun aplikasi secara manual][BUILD] (jangan khawatir, tidak terlalu sulit).
+
+
+### Windows
+
+Untuk Windows, untuk kesederhanaan, arsip prebuilt dengan semua dependensi (termasuk `adb`) tersedia :
+
+ - [`scrcpy-win64-v1.16.zip`][direct-win64]  
+   _(SHA-256: 3f30dc5db1a2f95c2b40a0f5de91ec1642d9f53799250a8c529bc882bc0918f0)_
+
+[direct-win64]: https://github.com/Genymobile/scrcpy/releases/download/v1.16/scrcpy-win64-v1.16.zip
+
+Ini juga tersedia di [Chocolatey]:

+choco install adb    # jika Anda belum memilikinya
+```
+
+Dan di [Scoop]:
+
+```bash

+```
+
+[Scoop]: https://scoop.sh
+
+Anda juga dapat [membangun aplikasi secara manual][BUILD].
+
+
+### macOS
+
+Aplikasi ini tersedia di [Homebrew]. Instal saja:
+
+[Homebrew]: https://brew.sh/
+
+```bash
+brew install scrcpy
+```
+Anda membutuhkan `adb`, dapat diakses dari `PATH` Anda. Jika Anda belum memilikinya:
+
+```bash
+brew cask install android-platform-tools
+```
+
+Anda juga dapat [membangun aplikasi secara manual][BUILD].
+
+
+## Menjalankan
+
+Pasang perangkat Android, dan jalankan:
+
+```bash
+scrcpy
+```
+
+Ini menerima argumen baris perintah, didaftarkan oleh:
+
+```bash
+scrcpy --help
+```
+
+## Fitur
+
+### Menangkap konfigurasi
+
+#### Mengurangi ukuran
+
+Kadang-kadang, berguna untuk mencerminkan perangkat Android dengan definisi yang lebih rendah untuk meningkatkan kinerja.
+
+Untuk membatasi lebar dan tinggi ke beberapa nilai (mis. 1024):
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # versi pendek
+```
+
+Dimensi lain dihitung agar rasio aspek perangkat dipertahankan.
+Dengan begitu, perangkat 1920×1080 akan dicerminkan pada 1024×576.
+
+#### Ubah kecepatan bit
+
+Kecepatan bit default adalah 8 Mbps. Untuk mengubah bitrate video (mis. Menjadi 2 Mbps):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # versi pendek
+```
+
+#### Batasi frekuensi gambar
+
+Kecepatan bingkai pengambilan dapat dibatasi:
+
+```bash
+scrcpy --max-fps 15
+```
+
+Ini secara resmi didukung sejak Android 10, tetapi dapat berfungsi pada versi sebelumnya.
+
+#### Memotong
+
+Layar perangkat dapat dipotong untuk mencerminkan hanya sebagian dari layar.
+
+Ini berguna misalnya untuk mencerminkan hanya satu mata dari Oculus Go:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 1224x1440 Mengimbangi (0,0)
+```
+
+Jika `--max-size` juga ditentukan, pengubahan ukuran diterapkan setelah pemotongan.
+
+
+#### Kunci orientasi video
+
+Untuk mengunci orientasi pencerminan:
+
+```bash
+scrcpy --lock-video-orientation 0   # orientasi alami
+scrcpy --lock-video-orientation 1   # 90° berlawanan arah jarum jam
+scrcpy --lock-video-orientation 2   # 180°
+scrcpy --lock-video-orientation 3   # 90° searah jarum jam
+```
+
+Ini mempengaruhi orientasi perekaman.
+
+
+### Rekaman
+
+Anda dapat merekam layar saat melakukan mirroring:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+Untuk menonaktifkan pencerminan saat merekam:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# berhenti merekam dengan Ctrl+C
+```
+
+"Skipped frames" are recorded, even if they are not displayed in real time (for
+performance reasons). Frames are _timestamped_ on the device, so [packet delay
+variation] does not impact the recorded file.
+
+"Frame yang dilewati" direkam, meskipun tidak ditampilkan secara real time (untuk alasan performa). Bingkai *diberi stempel waktu* pada perangkat, jadi [variasi penundaan paket] tidak memengaruhi file yang direkam.
+
+[variasi penundaan paket]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+### Koneksi
+
+#### Wireless
+
+_Scrcpy_ menggunakan `adb` untuk berkomunikasi dengan perangkat, dan` adb` dapat [terhubung] ke perangkat melalui TCP / IP:
+
+1. Hubungkan perangkat ke Wi-Fi yang sama dengan komputer Anda.
+2. Dapatkan alamat IP perangkat Anda (dalam Pengaturan → Tentang ponsel → Status).
+3. Aktifkan adb melalui TCP / IP pada perangkat Anda: `adb tcpip 5555`.
+4. Cabut perangkat Anda.
+5. Hubungkan ke perangkat Anda: `adb connect DEVICE_IP: 5555` (*ganti* *`DEVICE_IP`*).
+6. Jalankan `scrcpy` seperti biasa.
+
+Mungkin berguna untuk menurunkan kecepatan bit dan definisi:
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # versi pendek
+```
+
+[terhubung]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### Multi-perangkat
+
+Jika beberapa perangkat dicantumkan di `adb devices`, Anda harus menentukan _serial_:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # versi pendek
+```
+
+If the device is connected over TCP/IP:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # versi pendek
+```
+
+Anda dapat memulai beberapa contoh _scrcpy_ untuk beberapa perangkat.
+
+#### Mulai otomatis pada koneksi perangkat
+
+Anda bisa menggunakan [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### Koneksi via SSH tunnel
+
+Untuk menyambung ke perangkat jarak jauh, dimungkinkan untuk menghubungkan klien `adb` lokal ke server `adb` jarak jauh (asalkan mereka menggunakan versi yang sama dari _adb_ protocol):
+
+```bash
+adb kill-server    # matikan server adb lokal di 5037
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 komputer_jarak_jauh_anda
+# jaga agar tetap terbuka
+```
+
+Dari terminal lain:
+
+```bash
+scrcpy
+```
+
+Untuk menghindari mengaktifkan penerusan port jarak jauh, Anda dapat memaksa sambungan maju sebagai gantinya (perhatikan `-L`, bukan` -R`):
+
+```bash
+adb kill-server    # matikan server adb lokal di 5037
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 komputer_jarak_jauh_anda
+# jaga agar tetap terbuka
+```
+
+Dari terminal lain:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+Seperti koneksi nirkabel, mungkin berguna untuk mengurangi kualitas:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### Konfigurasi Jendela
+
+#### Judul
+
+Secara default, judul jendela adalah model perangkat. Itu bisa diubah:
+
+```bash
+scrcpy --window-title 'Perangkat Saya'
+```
+
+#### Posisi dan ukuran
+
+Posisi dan ukuran jendela awal dapat ditentukan:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### Jendela tanpa batas
+
+Untuk menonaktifkan dekorasi jendela:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### Selalu di atas
+
+Untuk menjaga jendela scrcpy selalu di atas:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### Layar penuh
+
+Aplikasi dapat dimulai langsung dalam layar penuh::
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # versi pendek
+```
+
+Layar penuh kemudian dapat diubah secara dinamis dengan <kbd>MOD</kbd>+<kbd>f</kbd>.
+
+#### Rotasi
+
+Jendela mungkin diputar:
+
+```bash
+scrcpy --rotation 1
+```
+
+Nilai yang mungkin adalah:
+ - `0`: tidak ada rotasi
+ - `1`: 90 derajat berlawanan arah jarum jam
+ - `2`: 180 derajat
+ - `3`: 90 derajat searah jarum jam
+
+Rotasi juga dapat diubah secara dinamis dengan <kbd>MOD</kbd>+<kbd>←</kbd>
+_(kiri)_ and <kbd>MOD</kbd>+<kbd>→</kbd> _(kanan)_.
+
+Perhatikan bahwa _scrcpy_ mengelola 3 rotasi berbeda::
+ - <kbd>MOD</kbd>+<kbd>r</kbd> meminta perangkat untuk beralih antara potret dan lanskap (aplikasi yang berjalan saat ini mungkin menolak, jika mendukung orientasi yang diminta).
+ - `--lock-video-orientation` mengubah orientasi pencerminan (orientasi video yang dikirim dari perangkat ke komputer). Ini mempengaruhi rekaman.
+ - `--rotation` (atau <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)
+   memutar hanya konten jendela. Ini hanya mempengaruhi tampilan, bukan rekaman.
+
+
+### Opsi pencerminan lainnya
+
+#### Hanya-baca
+
+Untuk menonaktifkan kontrol (semua yang dapat berinteraksi dengan perangkat: tombol input, peristiwa mouse, seret & lepas file):
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### Layar
+
+Jika beberapa tampilan tersedia, Anda dapat memilih tampilan untuk cermin:
+
+```bash
+scrcpy --display 1
+```
+
+Daftar id tampilan dapat diambil dengan::
+
+```
+adb shell dumpsys display   # cari "mDisplayId=" di keluaran
+```
+
+Tampilan sekunder hanya dapat dikontrol jika perangkat menjalankan setidaknya Android 10 (jika tidak maka akan dicerminkan dalam hanya-baca).
+
+
+#### Tetap terjaga
+
+Untuk mencegah perangkat tidur setelah beberapa penundaan saat perangkat dicolokkan:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+Keadaan awal dipulihkan ketika scrcpy ditutup.
+
+
+#### Matikan layar
+
+Dimungkinkan untuk mematikan layar perangkat saat pencerminan mulai dengan opsi baris perintah:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+Atau dengan menekan <kbd>MOD</kbd>+<kbd>o</kbd> kapan saja.
+
+Untuk menyalakannya kembali, tekan <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
+
+Di Android, tombol `POWER` selalu menyalakan layar. Untuk kenyamanan, jika `POWER` dikirim melalui scrcpy (melalui klik kanan atau<kbd>MOD</kbd>+<kbd>p</kbd>), itu akan memaksa untuk mematikan layar setelah penundaan kecil (atas dasar upaya terbaik).
+Tombol fisik `POWER` masih akan menyebabkan layar dihidupkan.
+
+Ini juga berguna untuk mencegah perangkat tidur:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+#### Render frame kedaluwarsa
+
+Secara default, untuk meminimalkan latensi, _scrcpy_ selalu menampilkan frame yang terakhir didekodekan tersedia, dan menghapus frame sebelumnya.
+
+Untuk memaksa rendering semua frame (dengan kemungkinan peningkatan latensi), gunakan:
+
+```bash
+scrcpy --render-expired-frames
+```
+
+#### Tunjukkan sentuhan
+
+Untuk presentasi, mungkin berguna untuk menunjukkan sentuhan fisik (pada perangkat fisik).
+
+Android menyediakan fitur ini di _Opsi Pengembang_.
+
+_Scrcpy_ menyediakan opsi untuk mengaktifkan fitur ini saat mulai dan mengembalikan nilai awal saat keluar:
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+Perhatikan bahwa ini hanya menunjukkan sentuhan _fisik_ (dengan jari di perangkat).
+
+
+#### Nonaktifkan screensaver
+
+Secara default, scrcpy tidak mencegah screensaver berjalan di komputer.
+
+Untuk menonaktifkannya:
+
+```bash
+scrcpy --disable-screensaver
+```
+
+
+### Kontrol masukan
+
+#### Putar layar perangkat
+
+Tekan <kbd>MOD</kbd>+<kbd>r</kbd> untuk beralih antara mode potret dan lanskap.
+
+Perhatikan bahwa itu berputar hanya jika aplikasi di latar depan mendukung orientasi yang diminta.
+
+#### Salin-tempel
+
+Setiap kali papan klip Android berubah, secara otomatis disinkronkan ke papan klip komputer.
+
+Apa saja <kbd>Ctrl</kbd> pintasan diteruskan ke perangkat. Khususnya:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> biasanya salinan
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> biasanya memotong
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> biasanya menempel (setelah sinkronisasi papan klip komputer-ke-perangkat)
+
+Ini biasanya berfungsi seperti yang Anda harapkan.
+
+Perilaku sebenarnya tergantung pada aplikasi yang aktif. Sebagai contoh,
+_Termux_ mengirim SIGINT ke <kbd>Ctrl</kbd>+<kbd>c</kbd> sebagai gantinya, dan _K-9 Mail_ membuat pesan baru.
+
+Untuk menyalin, memotong dan menempel dalam kasus seperti itu (tetapi hanya didukung di Android> = 7):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> injeksi `COPY` _(salin)_
+ - <kbd>MOD</kbd>+<kbd>x</kbd> injeksi `CUT` _(potong)_
+ - <kbd>MOD</kbd>+<kbd>v</kbd> injeksi `PASTE` (setelah sinkronisasi papan klip komputer-ke-perangkat)
+
+Tambahan, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> memungkinkan untuk memasukkan teks papan klip komputer sebagai urutan peristiwa penting. Ini berguna ketika komponen tidak menerima penempelan teks (misalnya di _Termux_), tetapi dapat merusak konten non-ASCII.
+
+**PERINGATAN:** Menempelkan papan klip komputer ke perangkat (baik melalui
+<kbd>Ctrl</kbd>+<kbd>v</kbd> or <kbd>MOD</kbd>+<kbd>v</kbd>) menyalin konten ke clipboard perangkat. Akibatnya, aplikasi Android apa pun dapat membaca kontennya. Anda harus menghindari menempelkan konten sensitif (seperti kata sandi) seperti itu.
+
+
+#### Cubit untuk memperbesar/memperkecil
+
+Untuk mensimulasikan "cubit-untuk-memperbesar/memperkecil": <kbd>Ctrl</kbd>+_klik-dan-pindah_.
+
+Lebih tepatnya, tahan <kbd>Ctrl</kbd> sambil menekan tombol klik kiri. Hingga tombol klik kiri dilepaskan, semua gerakan mouse berskala dan memutar konten (jika didukung oleh aplikasi) relatif ke tengah layar.
+
+Secara konkret, scrcpy menghasilkan kejadian sentuh tambahan dari "jari virtual" di lokasi yang dibalik melalui bagian tengah layar.
+
+
+#### Preferensi injeksi teks
+
+Ada dua jenis [peristiwa][textevents] dihasilkan saat mengetik teks:
+- _peristiwa penting_, menandakan bahwa tombol ditekan atau dilepaskan;
+- _peristiwa teks_, menandakan bahwa teks telah dimasukkan.
+
+Secara default, huruf dimasukkan menggunakan peristiwa kunci, sehingga keyboard berperilaku seperti yang diharapkan dalam game (biasanya untuk tombol WASD).
+
+Tapi ini mungkin [menyebabkan masalah][prefertext]. Jika Anda mengalami masalah seperti itu, Anda dapat menghindarinya dengan:
+
+```bash
+scrcpy --prefer-text
+```
+
+(tapi ini akan merusak perilaku keyboard dalam game)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### Ulangi kunci
+
+Secara default, menahan tombol akan menghasilkan peristiwa kunci yang berulang. Ini dapat menyebabkan masalah kinerja di beberapa game, di mana acara ini tidak berguna.
+
+Untuk menghindari penerusan peristiwa penting yang berulang:
+
+```bash
+scrcpy --no-key-repeat
+```
+
+
+### Seret/jatuhkan file
+
+#### Pasang APK
+
+Untuk menginstal APK, seret & lepas file APK (diakhiri dengan `.apk`) ke jendela _scrcpy_.
+
+Tidak ada umpan balik visual, log dicetak ke konsol.
+
+
+#### Dorong file ke perangkat
+
+Untuk mendorong file ke `/sdcard/` di perangkat, seret & jatuhkan file (non-APK) ke jendela _scrcpy_.
+
+Tidak ada umpan balik visual, log dicetak ke konsol.
+
+Direktori target dapat diubah saat mulai:
+
+```bash
+scrcpy --push-target /sdcard/foo/bar/
+```
+
+
+### Penerusan audio
+
+Audio tidak diteruskan oleh _scrcpy_. Gunakan [sndcpy].
+
+Lihat juga [Masalah #14].
+
+[sndcpy]: https://github.com/rom1v/sndcpy
+[Masalah #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## Pintasan
+
+Dalam daftar berikut, <kbd>MOD</kbd> adalah pengubah pintasan. Secara default, ini (kiri) <kbd>Alt</kbd> atau (kiri) <kbd>Super</kbd>.
+
+Ini dapat diubah menggunakan `--shortcut-mod`. Kunci yang memungkinkan adalah `lctrl`,`rctrl`, `lalt`,` ralt`, `lsuper` dan` rsuper`. Sebagai contoh:
+
+```bash
+# gunakan RCtrl untuk jalan pintas
+scrcpy --shortcut-mod=rctrl
+
+# gunakan baik LCtrl+LAlt atau LSuper untuk jalan pintas

 #### Copy-paste
 
-It is possible to synchronize clipboards between the computer and the device, in
-both directions:
+Any time the Android clipboard changes, it is automatically synchronized to the
+computer clipboard.
 
- - `Ctrl`+`c` copies the device clipboard to the computer clipboard;
- - `Ctrl`+`Shift`+`v` copies the computer clipboard to the device clipboard (and
-   pastes if the device runs Android >= 7);
- - `Ctrl`+`v` _pastes_ the computer clipboard as a sequence of text events (but
-   breaks non-ASCII characters).
+Any <kbd>Ctrl</kbd> shortcut is forwarded to the device. In particular:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> typically copies
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> typically cuts
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> typically pastes (after computer-to-device
+   clipboard synchronization)
+
+This typically works as you expect.
+
+The actual behavior depends on the active application though. For example,
+_Termux_ sends SIGINT on <kbd>Ctrl</kbd>+<kbd>c</kbd> instead, and _K-9 Mail_
+composes a new message.
+
+To copy, cut and paste in such cases (but only supported on Android >= 7):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> injects `COPY`
+ - <kbd>MOD</kbd>+<kbd>x</kbd> injects `CUT`
+ - <kbd>MOD</kbd>+<kbd>v</kbd> injects `PASTE` (after computer-to-device
+   clipboard synchronization)
+
+In addition, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> allows to inject the
+computer clipboard text as a sequence of key events. This is useful when the
+component does not accept text pasting (for example in _Termux_), but it can
+break non-ASCII content.
+
+**WARNING:** Pasting the computer clipboard to the device (either via
+<kbd>Ctrl</kbd>+<kbd>v</kbd> or <kbd>MOD</kbd>+<kbd>v</kbd>) copies the content
+into the device clipboard. As a consequence, any Android application could read
+its content. You should avoid to paste sensitive content (like passwords) that
+way.
+
+Some devices do not behave as expected when setting the device clipboard
+programmatically. An option `--legacy-paste` is provided to change the behavior
+of <kbd>Ctrl</kbd>+<kbd>v</kbd> and <kbd>MOD</kbd>+<kbd>v</kbd> so that they
+also inject the computer clipboard text as a sequence of key events (the same
+way as <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>).
+
+#### Pinch-to-zoom
+
+To simulate "pinch-to-zoom": <kbd>Ctrl</kbd>+_click-and-move_.
+
+More precisely, hold <kbd>Ctrl</kbd> while pressing the left-click button. Until
+the left-click button is released, all mouse movements scale and rotate the
+content (if supported by the app) relative to the center of the screen.
+
+Concretely, scrcpy generates additional touch events from a "virtual finger" at
+a location inverted through the center of the screen.
 
-Moreover, any time the Android clipboard changes, it is automatically
-synchronized to the computer clipboard.

+
+您可以使用[Homebrew]下载scrcpy。直接安装就可以了：
+
+[Homebrew]: https://brew.sh/
+
+```bash
+brew install scrcpy
+```
+
+您需要 `adb`以使用scrcpy，并且它需要可以通过 `PATH`被访问。如果您没有：
+
+```bash
+brew cask install android-platform-tools
+```
+
+您也可以[自行编译][编译]。
+
+
+## 运行scrcpy
+
+用USB链接电脑和安卓设备，并执行：
+
+```bash
+scrcpy
+```
+
+支持带命令行参数执行，查看参数列表：
+
+```bash
+scrcpy --help
+```
+
+## 功能介绍
+
+### 画面设置
+
+#### 缩小分辨率
+
+有时候，将设备屏幕镜像分辨率降低可以有效地提升性能。
+
+我们可以将高度和宽度都限制在一定大小内（如 1024）：
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # short version
+```
+
+较短的一边会被按比例缩小以保持设备的显示比例。
+这样，1920x1080 的设备会以 1024x576 的分辨率显示。
+
+
+#### 修改画面比特率
+
+默认的比特率是8Mbps。如果要改变画面的比特率 (比如说改成2Mbps)：
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # short version
+```
+
+#### 限制画面帧率
+
+画面的帧率可以通过下面的命令被限制：
+
+```bash
+scrcpy --max-fps 15
+```
+
+这个功能仅在Android 10和以后的版本被Android官方支持，但也有可能在更早的版本可用。
+
+#### 画面裁剪
+
+设备画面可在裁切后进行镜像，以显示部分屏幕。
+
+这项功能可以用于，例如，只显示Oculus Go的一只眼睛。
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 1224x1440 at offset (0,0)
+```
+
+如果`--max-size`在同时被指定，分辨率的改变将在画面裁切后进行。
+
+
+#### 锁定屏幕朝向
+
+
+可以使用如下命令锁定屏幕朝向：
+
+```bash
+scrcpy --lock-video-orientation 0   # 自然朝向
+scrcpy --lock-video-orientation 1   # 90° 逆时针旋转
+scrcpy --lock-video-orientation 2   # 180°
+scrcpy --lock-video-orientation 3   # 90° 顺时针旋转
+```
+
+该设定影响录制。
+
+
+### 屏幕录制
+
+可以在屏幕镜像的同时录制视频：
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+在不开启屏幕镜像的同时录制：
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# 按Ctrl+C以停止录制
+```
+
+在显示中“被跳过的帧”会被录制，虽然它们由于性能原因没有实时显示。
+在传输中每一帧都有 _时间戳_ ，所以 [包时延变化] 并不影响录制的文件。
+
+[包时延变化]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+### 连接方式
+
+#### 无线
+
+_Scrcpy_ 使用`adb`来与安卓设备连接。同时，`adb`能够通过TCP/IP[连接]到安卓设备:
+
+1. 将您的安卓设备和电脑连接至同一Wi-Fi。
+2. 获取安卓设备的IP地址（在设置-关于手机-状态信息）。
+3. 打开安卓设备的网络adb功能`adb tcpip 5555`。
+4. 将您的设备与电脑断开连接。
+5. 连接到您的设备：`adb connect DEVICE_IP:5555` _(用设备IP替换 `DEVICE_IP`)_.
+6. 运行`scrcpy`。
+
+降低比特率和分辨率可能有助于性能：
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # short version
+```
+
+[连接]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### 多设备
+
+如果多个设备在执行`adb devices`后被列出，您必须指定设备的 _序列号_ ：
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # short version
+```
+
+如果设备是通过TCP/IP方式连接到电脑的：
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # short version
+```
+
+您可以同时启动多个 _scrcpy_ 实例以同时显示多个设备的画面。
+
+#### 在设备连接时自动启动
+
+您可以使用 [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### SSH 连接
+
+本地的 adb 可以远程连接到另一个 adb 服务器（假设两者的adb版本相同），来远程连接到设备：
+
+```bash
+adb kill-server    # 关闭本地5037端口上的adb服务器
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# 保持该窗口开启
+```
+
+从另一个终端：
+
+```bash
+scrcpy
+```
+
+为了避免启动远程端口转发，你可以强制启动一个转发连接（注意`-L`和`-R`的区别：
+
+```bash
+adb kill-server    # kill the local adb server on 5037
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# 保持该窗口开启
+```
+
+从另一个终端:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+
+和无线网络连接类似，下列设置可能对改善性能有帮助：
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### 窗口设置
+
+#### 标题
+
+窗口的标题默认为设备型号。您可以通过如下命令修改它：
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+#### 位置和大小
+
+您可以指定初始的窗口位置和大小：
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### 无边框
+
+关闭边框：
+
+```bash
+scrcpy --window-borderless
+```
+
+#### 保持窗口在最前
+
+您可以通过如下命令保持窗口在最前面：
+
+```bash
+scrcpy --always-on-top
+```
+
+#### 全屏
+
+您可以通过如下命令直接全屏启动scrcpy：
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # short version
+```
+
+全屏状态可以通过<kbd>MOD</kbd>+<kbd>f</kbd>实时改变。
+
+#### 旋转
+
+通过如下命令，窗口可以旋转：
+
+```bash
+scrcpy --rotation 1
+```
+
+可选的值有：
+ - `0`: 无旋转
+ - `1`: 逆时针旋转90°
+ - `2`: 旋转180°
+ - `3`: 顺时针旋转90°
+
+这同样可以使用<kbd>MOD</kbd>+<kbd>←</kbd>
+_(左)_ 和 <kbd>MOD</kbd>+<kbd>→</kbd> _(右)_ 的快捷键实时更改。
+
+需要注意的是， _scrcpy_ 控制三个不同的朝向：
+ - <kbd>MOD</kbd>+<kbd>r</kbd> 请求设备在竖屏和横屏之间切换（如果前台应用程序不支持所请求的朝向，可能会拒绝该请求）。
+
+ - `--lock-video-orientation` 改变镜像的朝向（设备镜像到电脑的画面朝向）。这会影响录制。
+
+ - `--rotation` （或<kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>）
+   只旋转窗口的画面。这只影响显示，不影响录制。
+
+
+### 其他镜像设置
+
+#### 只读
+
+关闭电脑对设备的控制（如键盘输入、鼠标移动和文件传输）：
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### 显示屏
+
+如果有多个显示屏可用，您可以选择特定显示屏进行镜像：
+
+```bash
+scrcpy --display 1
+```
+
+您可以通过如下命令找到显示屏的id：
+
+```
+adb shell dumpsys display   # 在回显中搜索“mDisplayId=”
+```
+
+第二显示屏可能只能在设备运行Android 10或以上的情况下被控制（它可能会在电脑上显示，但无法通过电脑操作）。
+
+
+#### 保持常亮
+
+防止设备在已连接的状态下休眠：
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+程序关闭后，设备设置会恢复原样。
+
+
+#### 关闭设备屏幕
+
+在启动屏幕镜像时，可以通过如下命令关闭设备的屏幕：
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+或者在需要的时候按<kbd>MOD</kbd>+<kbd>o</kbd>。
+
+要重新打开屏幕的话，需要按<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
+
+在Android上,`电源`按钮始终能把屏幕打开。
+
+为了方便，如果按下`电源`按钮的事件是通过 _scrcpy_ 发出的（通过点按鼠标右键或<kbd>MOD</kbd>+<kbd>p</kbd>），它会在短暂的延迟后将屏幕关闭。
+
+物理的`电源`按钮仍然能打开设备屏幕。
+
+同时，这项功能还能被用于防止设备休眠：
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+
+#### 渲染超时帧
+
+为了降低延迟， _scrcpy_ 默认渲染解码成功的最近一帧，并跳过前面任意帧。
+
+强制渲染所有帧（可能导致延迟变高）：
+
+```bash
+scrcpy --render-expired-frames
+```
+
+#### 显示触摸
+
+在展示时，有些时候可能会用到显示触摸点这项功能（在设备上显示）。
+
+Android在 _开发者设置_ 中提供了这项功能。
+
+_Scrcpy_ 提供一个选项可以在启动时开启这项功能并在退出时恢复初始设置：
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+请注意这项功能只能显示 _物理_ 触摸（要用手在屏幕上触摸）。
+
+
+#### 关闭屏保
+
+_Scrcpy_ 不会默认关闭屏幕保护。
+
+关闭屏幕保护：
+
+```bash
+scrcpy --disable-screensaver
+```
+
+
+### 输入控制
+
+#### 旋转设备屏幕
+
+使用<kbd>MOD</kbd>+<kbd>r</kbd>以在竖屏和横屏模式之间切换。
+
+需要注意的是，只有在前台应用程序支持所要求的模式时，才会进行切换。
+
+#### 复制黏贴
+
+每次Android的剪贴板变化的时候，它都会被自动同步到电脑的剪贴板上。
+
+所有的 <kbd>Ctrl</kbd> 快捷键都会被转发至设备。其中：
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> 复制
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> 剪切
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> 黏贴 （在电脑到设备的剪贴板同步完成之后）
+
+这通常如您所期望的那样运作。
+
+但实际的行为取决于设备上的前台程序。
+例如 _Termux_ 在<kbd>Ctrl</kbd>+<kbd>c</kbd>被按下时发送 SIGINT，
+又如 _K-9 Mail_ 会新建一封新邮件。
+
+在这种情况下剪切复制黏贴（仅在Android >= 7时可用）：
+ - <kbd>MOD</kbd>+<kbd>c</kbd> 注入 `COPY`（复制）
+ - <kbd>MOD</kbd>+<kbd>x</kbd> 注入 `CUT`（剪切）
+ - <kbd>MOD</kbd>+<kbd>v</kbd> 注入 `PASTE`（黏贴）（在电脑到设备的剪贴板同步完成之后）
+
+另外，<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>可以将电脑的剪贴板内容转换为一串按键事件输入到设备。
+在应用程序不接受黏贴时（比如 _Termux_ ），这项功能可以排上一定的用场。
+需要注意的是，这项功能可能会导致非ASCII编码的内容出现错误。
+
+**警告：** 将电脑剪贴板的内容黏贴至设备（无论是通过<kbd>Ctrl</kbd>+<kbd>v</kbd>还是<kbd>MOD</kbd>+<kbd>v</kbd>）
+都需要将内容保存至设备的剪贴板。如此，任何一个应用程序都可以读取它。
+您应当避免将敏感内容通过这种方式传输（如密码）。
+
+
+#### 捏拉缩放
+
+模拟 “捏拉缩放”：<kbd>Ctrl</kbd>+_按住并移动鼠标_。
+
+更准确的说，您需要在按住<kbd>Ctrl</kbd>的同时按住并移动鼠标。
+在鼠标左键松开之后，光标的任何操作都会相对于屏幕的中央进行。
+
+具体来说， _scrcpy_ 使用“虚拟手指”以在相对于屏幕中央相反的位置产生触摸事件。
+
+
+#### 文字注入偏好
+
+打字的时候，系统会产生两种[事件][textevents]：
+ - _按键事件_ ，代表一个按键被按下/松开。
+ - _文本事件_ ，代表一个文本被输入。
+
+程序默认使用按键事件来输入字母。只有这样，键盘才会在游戏中正常运作（尤其WASD键）。
+
+但这也有可能[造成问题][prefertext]。如果您遇到了这样的问题，您可以通过下列操作避免它：
+
+```bash
+scrcpy --prefer-text
+```
+
+（这会导致键盘在游戏中工作不正常）
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### 按键重复
+
+当你一直按着一个按键不放时，程序默认产生多个按键事件。
+在某些游戏中这可能会导致性能问题。
+
+避免转发重复按键事件：
+
+```bash
+scrcpy --no-key-repeat
+```
+
+
+### 文件传输
+
+#### 安装APK
+
+如果您要要安装APK，请拖放APK文件（文件名以`.apk`结尾）到 _scrcpy_ 窗口。
+
+该操作在屏幕上不会出现任何变化，而会在控制台输出一条日志。
+
+
+#### 将文件推送至设备
+
+如果您要推送文件到设备的 `/sdcard/`，请拖放文件至（不能是APK文件）_scrcpy_ 窗口。
+
+该操作没有可见的响应，只会在控制台输出日志。
+
+在启动时可以修改目标目录：
+
+```bash
+scrcpy --push-target /sdcard/foo/bar/
+```
+
+
+### 音频转发
+
+_scrcpy_ 不支持音频。请使用 [sndcpy].
+
+另外请阅读 [issue #14]。
+
+[sndcpy]: https://github.com/rom1v/sndcpy
+[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## 热键
+
+在下列表格中, <kbd>MOD</kbd> 是热键的修饰键。
+默认是（左）<kbd>Alt</kbd>或者（左）<kbd>Super</kbd>。
+
+您可以使用 `--shortcut-mod`后缀来修改它。可选的按键有`lctrl`、`rctrl`、
+`lalt`、`ralt`、`lsuper`和`rsuper`。如下例：
+
+```bash
+# 使用右侧的Ctrl键
+scrcpy --shortcut-mod=rctrl
+
+# 使用左侧的Ctrl键、Alt键或Super键
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_一般来说，<kbd>[Super]</kbd>就是<kbd>Windows</kbd>或者<kbd>Cmd</kbd>。_
+

+
+## 自定义路径
+
+为了使用您想使用的 _adb_ ，您可以在环境变量
+`ADB`中设置它的路径：
+
+    ADB=/path/to/adb scrcpy
+
+如果需要覆盖`scrcpy-server`的路径，您可以在
+`SCRCPY_SERVER_PATH`中设置它。

+# scrcpy (v1.15)
+
+Scrcpy 可以透過 USB、或是 [TCP/IP][article-tcpip] 來顯示或控制 Android 裝置。且 scrcpy 不需要 _root_ 權限。
+
+Scrcpy 目前支援 _GNU/Linux_、_Windows_ 和 _macOS_。
+
+![screenshot](assets/screenshot-debian-600.jpg)
+
+特色:
+
+ - **輕量** (只顯示裝置螢幕)
+ - **效能** (30~60fps)
+ - **品質** (1920×1080 或更高)
+ - **低延遲** ([35~70ms][lowlatency])
+ - **快速啟動** (~1 秒就可以顯示第一個畫面)
+ - **非侵入性** (不安裝、留下任何東西在裝置上)
+
+[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
+
+
+## 需求
+
+Android 裝置必須是 API 21+ (Android 5.0+)。
+
+請確認裝置上的 [adb 偵錯 (通常位於開發者模式內)][enable-adb] 已啟用。
+
+[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
+
+
+在部分的裝置上，你也必須啟用[特定的額外選項][control]才能使用鍵盤和滑鼠控制。
+
+[control]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323

+
+
+
+### Windows
+
+為了保持簡單，Windows 用戶可以下載一個包含所有必需軟體 (包含 `adb`) 的壓縮包:
+
+- [`scrcpy-win64-v1.15.zip`][direct-win64]  
+   _(SHA-256: dd514bb591e63ef4cd52a53c30f1153a28f59722d64690eb07bd017849edcba2)_

+```
+
+[Scoop]: https://scoop.sh
+
+你也可以自己[編譯 _Scrcpy_][BUILD]。
+
+
+### macOS
+
+_Scrcpy_ 可以在 [Homebrew] 上直接安裝:
+
+[Homebrew]: https://brew.sh/
+
+```bash
+brew install scrcpy
+```
+
+由於執行期間需要可以藉由 `PATH` 存取 `adb` 。如果還沒有安裝 `adb` 可以使用下列方式安裝:
+
+```bash
+brew cask install android-platform-tools
+```
+
+你也可以自己[編譯 _Scrcpy_][BUILD]。
+
+
+## 執行
+
+將電腦和你的 Android 裝置連線，然後執行:
+
+```bash
+scrcpy
+```
+
+_Scrcpy_ 可以接受命令列參數。輸入下列指令就可以瀏覽可以使用的命令列參數:
+
+```bash
+scrcpy --help
+```
+
+
+## 功能
+
+> 以下說明中，有關快捷鍵的說明可能會出現 <kbd>MOD</kbd> 按鈕。相關說明請參見[快捷鍵]內的說明。
+
+[快捷鍵]: #快捷鍵
+
+### 畫面擷取
+
+#### 縮小尺寸
+
+使用比較低的解析度來投放 Android 裝置在某些情況可以提升效能。
+
+限制寬和高的最大值(例如: 1024):
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # 縮短版本
+```
+
+比較小的參數會根據螢幕比例重新計算。
+根據上面的範例，1920x1080 會被縮小成 1024x576。
+
+
+#### 更改 bit-rate
+
+預設的 bit-rate 是 8 Mbps。如果要更改 bit-rate (例如: 2 Mbps):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # 縮短版本
+```
+
+#### 限制 FPS
+
+限制畫面最高的 FPS:
+
+```bash
+scrcpy --max-fps 15
+```
+
+僅在 Android 10 後正式支援，不過也有可能可以在 Android 10 以前的版本使用。
+
+#### 裁切
+
+裝置的螢幕可以裁切。如此一來，鏡像出來的螢幕就只會是原本的一部份。
+
+假如只要鏡像 Oculus Go 的其中一隻眼睛:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 位於 (0,0)，大小1224x1440
+```
+
+如果 `--max-size` 也有指定的話，裁切後才會縮放。
+
+
+#### 鎖定影像方向
+
+
+如果要鎖定鏡像影像方向:
+
+```bash
+scrcpy --lock-video-orientation 0   # 原本的方向
+scrcpy --lock-video-orientation 1   # 逆轉 90°
+scrcpy --lock-video-orientation 2   # 180°
+scrcpy --lock-video-orientation 3   # 順轉 90°
+```
+
+這會影響錄影結果的影像方向。
+
+
+### 錄影
+
+鏡像投放螢幕的同時也可以錄影:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+如果只要錄影，不要投放螢幕鏡像的話:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# 用 Ctrl+C 停止錄影
+```
+
+就算有些幀為了效能而被跳過，它們還是一樣會被錄製。
+
+裝置上的每一幀都有時間戳記，所以 [封包延遲 (Packet Delay Variation, PDV)][packet delay variation] 並不會影響錄影的檔案。
+
+[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+### 連線
+
+#### 無線
+
+_Scrcpy_ 利用 `adb` 和裝置通訊，而 `adb` 可以[透過 TCP/IP 連結][connect]:
+
+1. 讓電腦和裝置連到同一個 Wi-Fi。
+2. 獲取手機的 IP 位址(設定 → 關於手機 → 狀態).
+3. 啟用裝置上的 `adb over TCP/IP`: `adb tcpip 5555`.
+4. 拔掉裝置上的線。
+5. 透過 TCP/IP 連接裝置: `adb connect DEVICE_IP:5555` _(把 `DEVICE_IP` 換成裝置的IP位址)_.
+6. 和平常一樣執行 `scrcpy`。
+
+如果效能太差，可以降低 bit-rate 和解析度:
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # 縮短版本
+```
+
+[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### 多裝置
+
+如果 `adb devices` 內有多個裝置，則必須附上 _serial_:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # 縮短版本
+```
+
+如果裝置是透過 TCP/IP 連線:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # 縮短版本
+```
+
+你可以啟用復數個對應不同裝置的 _scrcpy_。
+
+#### 裝置連結後自動啟動
+
+你可以使用 [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### SSH tunnel
+
+本地的 `adb` 可以連接到遠端的 `adb` 伺服器(假設兩者使用相同版本的 _adb_ 通訊協定)，以連接到遠端裝置:
+
+```bash
+adb kill-server    # 停止在 Port 5037 的本地 adb 伺服
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# 保持開啟
+```
+
+從另外一個終端機:
+
+```bash
+scrcpy
+```
+
+如果要避免啟用 remote port forwarding，你可以強制它使用 forward connection (注意 `-L` 和 `-R` 的差別):
+
+```bash
+adb kill-server    # 停止在 Port 5037 的本地 adb 伺服
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# 保持開啟
+```
+
+從另外一個終端機:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+
+和無線連接一樣，有時候降低品質會比較好:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### 視窗調整
+
+#### 標題
+
+預設標題是裝置的型號，不過可以透過以下方式修改:
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+#### 位置 & 大小
+
+初始的視窗位置和大小也可以指定:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### 無邊框
+
+如果要停用視窗裝飾:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### 保持最上層
+
+如果要保持 `scrcpy` 的視窗在最上層:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### 全螢幕
+
+這個軟體可以直接在全螢幕模式下起動:
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # 縮短版本
+```
+
+全螢幕可以使用 <kbd>MOD</kbd>+<kbd>f</kbd> 開關。
+
+#### 旋轉
+
+視窗可以旋轉:
+
+```bash
+scrcpy --rotation 1
+```
+
+可用的數值:
+ - `0`: 不旋轉
+ - `1`: 90 度**逆**轉
+ - `2`: 180 度
+ - `3`: 90 度**順**轉
+
+旋轉方向也可以使用 <kbd>MOD</kbd>+<kbd>←</kbd> _(左方向鍵)_ 和 <kbd>MOD</kbd>+<kbd>→</kbd> _(右方向鍵)_ 調整。
+
+_scrcpy_ 有 3 種不同的旋轉:
+ - <kbd>MOD</kbd>+<kbd>r</kbd> 要求裝置在垂直、水平之間旋轉 (目前運行中的 App 有可能會因為不支援而拒絕)。
+ - `--lock-video-orientation` 修改鏡像的方向 (裝置傳給電腦的影像)。這會影響錄影結果的影像方向。
+ - `--rotation` (或是 <kbd>MOD</kbd>+<kbd>←</kbd> / <kbd>MOD</kbd>+<kbd>→</kbd>) 只旋轉視窗的內容。這只會影響鏡像結果，不會影響錄影結果。
+
+
+### 其他鏡像選項
+
+#### 唯讀
+
+停用所有控制，包含鍵盤輸入、滑鼠事件、拖放檔案:
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### 顯示螢幕
+
+如果裝置有複數個螢幕，可以指定要鏡像哪個螢幕:
+
+```bash
+scrcpy --display 1
+```
+
+可以透過下列指令獲取螢幕 ID:
+
+```
+adb shell dumpsys display   # 找輸出結果中的 "mDisplayId="
+```
+
+第二螢幕只有在 Android 10+ 時可以控制。如果不是 Android 10+，螢幕就會在唯讀狀態下投放。
+
+
+#### 保持清醒
+
+如果要避免裝置在連接狀態下進入睡眠:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+_scrcpy_ 關閉後就會回復成原本的設定。
+
+
+#### 關閉螢幕
+
+鏡像開始時，可以要求裝置關閉螢幕:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+或是在任何時候輸入 <kbd>MOD</kbd>+<kbd>o</kbd>。
+
+如果要開啟螢幕，輸入 <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>。
+
+在 Android 上，`POWER` 按鈕總是開啟螢幕。
+
+為了方便，如果 `POWER` 是透過 scrcpy 轉送 (右鍵 或 <kbd>MOD</kbd>+<kbd>p</kbd>)的話，螢幕將會在短暫的延遲後關閉。
+
+實際在手機上的 `POWER` 還是會開啟螢幕。
+
+防止裝置進入睡眠狀態:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+
+#### 顯示過期的幀
+
+為了降低延遲， _scrcpy_ 預設只會顯示最後解碼的幀，並且拋棄所有在這之前的幀。
+
+如果要強制顯示所有的幀 (有可能會拉高延遲)，輸入:
+
+```bash
+scrcpy --render-expired-frames
+```
+
+#### 顯示觸控點
+
+對於要報告的人來說，顯示裝置上的實際觸控點有時候是有幫助的。
+
+Android 在_開發者選項_中有提供這個功能。
+
+_Scrcpy_ 可以在啟動時啟用這個功能，並且在停止後恢復成原本的設定:
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+這個選項只會顯示**實際觸碰在裝置上的觸碰點**。
+
+
+### 輸入控制
+
+
+#### 旋轉裝置螢幕
+
+輸入 <kbd>MOD</kbd>+<kbd>r</kbd> 以在垂直、水平之間切換。
+
+如果使用中的程式不支援，則不會切換。
+
+
+#### 複製/貼上
+
+如果 Android 剪貼簿上的內容有任何更動，電腦的剪貼簿也會一起更動。
+
+任何與 <kbd>Ctrl</kbd> 相關的快捷鍵事件都會轉送到裝置上。特別來說:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> 通常是複製
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> 通常是剪下
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> 通常是貼上 (在電腦的剪貼簿與裝置上的剪貼簿同步之後)
+
+這些跟你通常預期的行為一樣。
+
+但是，實際上的行為是根據目前運行中的應用程式而定。
+
+舉例來說， _Termux_ 在收到 <kbd>Ctrl</kbd>+<kbd>c</kbd> 後，會傳送 SIGINT；而 _K-9 Mail_ 則是建立新訊息。
+
+如果在這情況下，要剪下、複製或貼上 (只有在Android 7+時才支援):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> 注入 `複製`
+ - <kbd>MOD</kbd>+<kbd>x</kbd> 注入 `剪下`
+ - <kbd>MOD</kbd>+<kbd>v</kbd> 注入 `貼上` (在電腦的剪貼簿與裝置上的剪貼簿同步之後)
+
+另外，<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> 則是以一連串的按鍵事件貼上電腦剪貼簿中的內容。當元件不允許文字貼上 (例如 _Termux_) 時，這就很有用。不過，這在非 ASCII 內容上就無法使用。
+
+**警告:** 貼上電腦的剪貼簿內容 (無論是從 <kbd>Ctrl</kbd>+<kbd>v</kbd> 或 <kbd>MOD</kbd>+<kbd>v</kbd>) 時，會複製剪貼簿中的內容至裝置的剪貼簿上。這會讓所有 Android 程式讀取剪貼簿的內容。請避免貼上任何敏感內容 (像是密碼)。
+
+
+#### 文字輸入偏好
+
+輸入文字時，有兩種[事件][textevents]會被觸發:
+ - _鍵盤事件 (key events)_，代表有一個按鍵被按下或放開
+ - _文字事件 (text events)_，代表有一個文字被輸入
+
+預設上，文字是被以鍵盤事件 (key events) 輸入的，所以鍵盤和遊戲內所預期的一樣 (通常是指 WASD)。
+
+但是這可能造成[一些問題][prefertext]。如果在這輸入這方面遇到了問題，你可以試試:
+
+```bash
+scrcpy --prefer-text
+```
+
+(不過遊戲內鍵盤就會不可用)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### 重複輸入
+
+通常來說，長時間按住一個按鍵會重複觸發按鍵事件。這會在一些遊戲中造成效能問題，而且這個重複的按鍵事件是沒有意義的。
+
+如果不要轉送這些重複的按鍵事件:
+
+```bash

+#### 安裝 APK
+
+如果要安裝 APK ，拖放一個 APK 檔案 (以 `.apk` 為副檔名) 到 _scrcpy_ 的視窗上。
+
+視窗上不會有任何反饋；結果會顯示在命令列中。
+
+
+#### 推送檔案至裝置
+
+如果要推送檔案到裝置上的 `/sdcard/` ，拖放一個非 APK 檔案 (**不**以 `.apk` 為副檔名) 到 _scrcpy_ 的視窗上。
+
+視窗上不會有任何反饋；結果會顯示在命令列中。
+
+推送檔案的目標路徑可以在啟動時指定:
+
+```bash
+scrcpy --push-target /sdcard/foo/bar/
+```

+## 快捷鍵
+
+在以下的清單中，<kbd>MOD</kbd> 是快捷鍵的特殊按鍵。通常來說，這個按鍵是 (左) <kbd>Alt</kbd> 或是 (左) <kbd>Super</kbd>。
+
+這個是可以使用 `--shortcut-mod` 更改的。可以用的選項有:
+- `lctrl`: 左邊的 <kbd>Ctrl</kbd>
+- `rctrl`: 右邊的 <kbd>Ctrl</kbd>
+- `lalt`: 左邊的 <kbd>Alt</kbd>
+- `ralt`: 右邊的 <kbd>Alt</kbd>
+- `lsuper`: 左邊的 <kbd>Super</kbd>
+- `rsuper`: 右邊的 <kbd>Super</kbd>
+
+```bash
+# 以 右邊的 Ctrl 為快捷鍵特殊按鍵
+scrcpy --shortcut-mod=rctrl
+
+# 以 左邊的 Ctrl 和左邊的 Alt 或是 左邊的 Super 為快捷鍵特殊按鍵
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> 通常是 <kbd>Windows</kbd> 或 <kbd>Cmd</kbd> 鍵。_

+## 自訂路徑
+
+如果要使用特定的 _adb_ ，將它設定到環境變數中的 `ADB`:
+
+    ADB=/path/to/adb scrcpy
+
+如果要覆寫 `scrcpy-server` 檔案的路徑，則將路徑設定到環境變數中的 `SCRCPY_SERVER_PATH`。
