 #### 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.

+# 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。

+
+_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
+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。_
+

+
+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`。
