wip_everything_broken

The video buffer held 3 frames:
 - the producer frame (for decoding)
 - the pending frame (to exchange between the producer and consumer)
 - the consumer frame (for rendering)

It worked well, but it prevented video buffers to be chained, because
the consumer frame of the first video buffer must be the same as the
producer frame of the second video buffer.

To solve this problem, make the decoder handle its decoding frame, and
keep only the pending and consumer frames in the video_buffer.

    decoder -> pending -> consumer -> pending -> consumer
             |---------------------||---------------------|
                  video_buffer 1         video_buffer 2

This paves the way to support asynchronous swscale.

+# 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]:

+
+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].

+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
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> biasanya adalah <kbd>Windows</kbd> atau <kbd>Cmd</kbd> key._

+```
+

+```
+
+[Scoop]: https://scoop.sh
+
+您也可以[自行编译][编译]。
+
+
+### macOS
+
+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+)。

+[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
+scrcpy --no-key-repeat
+```
+
+
+### 檔案
+
+#### 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/
+```
+
+
+### 音訊轉送
+
+_scrcpy_ **不**轉送音訊。請使用 [sndcpy]。另外，參見 [issue #14]。
+
+[sndcpy]: https://github.com/rom1v/sndcpy
+[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## 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`。
