Recording

To record video and audio streams while mirroring:

scrcpy --record=file.mp4
scrcpy -r file.mkv

To record only the video:

scrcpy --no-audio --record=file.mp4

To record only the audio:

scrcpy --no-video --record=file.opus
scrcpy --no-video --audio-codec=aac --record=file.aac
scrcpy --no-video --audio-codec=flac --record=file.flac
scrcpy --no-video --audio-codec=raw --record=file.wav

Note: .m4a/.mp4 and .mka/.mkv are also supported for opus, aac and flac.

Timestamps are captured on the device, so packet delay variation does not impact the recorded file, which is always clean (only if you use --record of course, not if you capture your scrcpy window and audio output on the computer).

Format

The video and audio streams are encoded on the device, but are muxed on the client side. Several formats (containers) are supported:

• MP4 (.mp4, .m4a, .aac)
• Matroska (.mkv, .mka)
• OPUS (.opus)
• FLAC (.flac)
• WAV (.wav)

The container is automatically selected based on the filename.

It is also possible to explicitly select a container (in that case the filename needs not end with a known extension):

scrcpy --record=file --record-format=mkv

Rotation

The video can be recorded rotated. See video orientation.

No Playback

To disable playback and control while recording:

scrcpy --no-playback --no-control --record=file.mp4

It is also possible to disable video and audio playback separately:

# Record both video and audio, but only play video
scrcpy --record=file.mkv --no-audio-playback

To also disable the window:

scrcpy --no-playback --no-window --record=file.mp4
# interrupt recording with Ctrl+C

Time Limit

To limit the recording time:

scrcpy --record=file.mkv --time-limit=20  # in seconds

The --time-limit option is not limited to recording, it also impacts simple mirroring:

scrcpy --time-limit=20

Suggested labels

None
