# 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
|
|
```

|
## 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
|
|
```

## Webcam
|
|
|
|
Combined with the [V4L2](v4l2.md) feature on Linux, the Android device camera
|
|
may be used as a webcam on the computer.
