To obtain uncompressed video and audio from the ivtv driver and the PVR-150: uncompressed video is available from /dev/video32 in an odd Conexant macroblock format that is called 'HM12' under linux. raw PCM audio samples are available from /dev/video24 Note that /dev/video0 is always MPEG-2 compressed video. I assume ffmpeg and mencoder can transcode from MPEG-2 PS to H.264 on the fly, however, they will consume more CPU to do the decompression of the MPEG-2 PS. The advantage of working with the MPEG-2 PS as the source is that one avoids the audio & video synchronization problem one might encounter working with the separate uncompressed audio & video streams.
