[Live-devel] Problem with recording incoming RTSP streams

[Ross Finlayson]

The basic problem here is that the ".mov"/".mp4" file format is ill-suited for recording incoming RTP streams, because, in those file formats, it is difficult to accurately record media frames with their accurate presentation times.  (VLC doesn't have this problem because it is decoding, then re-encoding the stream, even if it doesn't 'transcode' to a different codec or frame rate.)

The best solution is to use a better media file format - like Matroska - that allows us to record each frame with its precise presentation time.  We have a pending 'funded project' to add support for writing Matroska files:

Feel free to contribute to this project if you would like to see this happen.
