This allows for PCM playback during capture for supported devices. This requires at least the OpenGL patch series' "qv4l2: add Capture menu" patch. A device must be ALSA compatible in order to be used with the qv4l2. The ALSA implementation requires ALSA on the system. If ALSA support is not present, then this feature will not be compiled in. Some of the changes/improvements: - Capturing will also capture audio - Added audio controls to the capture menu - Selectable audio devices (can also have no audio) - Automatically find corresponding audio source for a given video device if applicable - Supports both radio, video and audio devices that uses PCM. - Bug fixes Known issues: - Sometimes when generating the audio in and out device lists, it may take some time for the combo boxes to render correctly. - If the audio causes underruns/overruns, try increase the audio buffer. - Not all audio input/output combination will work, depending on system and devices. - The A-V difference in ms is not always correct, but should still help as an indicator
