A new release of UV4L is out with a new “tiny” feature. You can now capture and record the audio/video live stream from the remote peer (e.g. a Raspberry Pi) into a standard webm container, that you can play back later or save to disk. All this can be done from within your browser at the usual /stream/webrtc web page (there’s a start/stop recording button right below the video box). As usual, this does not require any additional plug-in. With regard to the Raspberry Pi this means that you can easily record Full HD audio/videos at 30fps.
