+# Camera
+
+Camera mirroring is supported for devices with Android 12 or higher.
+
+To capture the camera instead of the device screen:
+
+```
+scrcpy --video-source=camera
+```
+
+By default, it automatically switches [audio source](audio.md#source) to
+microphone (as if `--audio-source=mic` were also passed).
+
+```bash
+scrcpy --video-source=display  # default is --audio-source=output
+scrcpy --video-source=camera   # default is --audio-source=mic
+scrcpy --video-source=display --audio-source=mic    # force display AND microphone
+scrcpy --video-source=camera --audio-source=output  # force camera AND device audio output
+```
+
+Audio can be disabled:
+
+```bash
+# audio not captured at all
+scrcpy --video-source=camera --no-audio
+scrcpy --video-source=camera --no-audio --record=file.mp4
+
+# audio captured and recorded, but not played
+scrcpy --video-source=camera --no-audio-playback --record=file.mp4
+```
+
+
+## List
+
+To list the cameras available (with their declared valid sizes and frame rates):
+
+```
+scrcpy --list-cameras
+scrcpy --list-camera-sizes
+```
+
+_Note that the sizes and frame rates are declarative. They are not accurate on
+all devices: some of them are declared but not supported, while some others are
+not declared but supported._
+
+
+## Selection
+
+It is possible to pass an explicit camera id (as listed by `--list-cameras`):
+
+```
+scrcpy --video-source=camera --camera-id=0
+```
+
+Alternatively, the camera may be selected automatically:
+
+```bash
+scrcpy --video-source=camera                           # use the first camera
+scrcpy --video-source=camera --camera-facing=front     # use the first front camera
+scrcpy --video-source=camera --camera-facing=back      # use the first back camera
+scrcpy --video-source=camera --camera-facing=external  # use the first external camera
+```
+
+If `--camera-id` is specified, then `--camera-facing` is forbidden (the id
+already determines the camera):
+
+```bash
+scrcpy --video-source=camera --camera-id=0 --camera-facing=front  # error
+```
+
+
+### Size selection
+
+It is possible to pass an explicit camera size:
+
+```
+scrcpy --video-source=camera --camera-size=1920x1080
+```
+
+The given size may be listed among the declared valid sizes
+(`--list-camera-sizes`), but may also be anything else (some devices support
+arbitrary sizes):
+
+```
+scrcpy --video-source=camera --camera-size=1840x444
+```
+
+Alternatively, a declared valid size (among the ones listed by
+`list-camera-sizes`) may be selected automatically.
+
+Two constraints are supported:
+ - `-m`/`--max-size` (already used for display mirroring), for example `-m1920`;
+ - `--camera-ar` to specify an aspect ratio (`<num>:<den>`, `<value>` or
+   `sensor`).
+
+Some examples:
+
+```bash
+scrcpy --video-source=camera                          # use the greatest width and the greatest associated height
+scrcpy --video-source=camera -m1920                   # use the greatest width not above 1920 and the greatest associated height
+scrcpy --video-source=camera --camera-ar=4:3          # use the greatest size with an aspect ratio of 4:3 (+/- 10%)
+scrcpy --video-source=camera --camera-ar=1.6          # use the greatest size with an aspect ratio of 1.6 (+/- 10%)
+scrcpy --video-source=camera --camera-ar=sensor       # use the greatest size with the aspect ratio of the camera sensor (+/- 10%)
+scrcpy --video-source=camera -m1920 --camera-ar=16:9  # use the greatest width not above 1920 and the closest to 16:9 aspect ratio
+```
+
+If `--camera-size` is specified, then `-m`/`--max-size` and `--camera-ar` are
+forbidden (the size is determined by the value given explicitly):
+
+```bash
+scrcpy --video-source=camera --camera-size=1920x1080 -m3000  # error
+```
+
+
+## Rotation
+
+To rotate the captured video, use the [video orientation](video.md#orientation)
+option:
+
+```
+scrcpy --video-source=camera --camera-size=1920x1080 --orientation=90
+```
+
+
+## Frame rate
+
+By default, camera is captured at Android's default frame rate (30 fps).
+
+To configure a different frame rate:
+
+```
+scrcpy --video-source=camera --camera-fps=60
+```
+
+
+## High speed capture
+
+The Android camera API also supports a [high speed capture mode][high speed].
+
+This mode is restricted to specific resolutions and frame rates, listed by
+`--list-camera-sizes`.
+
+```
+scrcpy --video-source=camera --camera-size=1920x1080 --camera-fps=240
+```
+
+[high speed]: https://developer.android.com/reference/android/hardware/camera2/CameraConstrainedHighSpeedCaptureSession
+
+
+## Brace expansion tip
+
+All camera options start with `--camera-`, so if your shell supports it, you can
+benefit from [brace expansion] (for example, it is supported _bash_ and _zsh_):
+
+```bash
+scrcpy --video-source=camera --camera-{facing=back,ar=16:9,high-speed,fps=120}
+```
+
+This will be expanded as:
+
+```bash
+scrcpy --video-source=camera --camera-facing=back --camera-ar=16:9 --camera-high-speed --camera-fps=120
+```
+
+[brace expansion]: https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html
+
+
+## Webcam
+
+Combined with the [V4L2](v4l2.md) feature on Linux, the Android device camera
+may be used as a webcam on the computer.
