Hi,

My goal is to play an H264 stream that comes from a camera. I am decoding using libav. According to H264 standard, it is not necessary to specify the time_scale info in the SDP/SPS.

Everything is working fine, however I need to synchronize playback to prevent stutters. I am parsing the nal units in my H264Sink, in which I get a presentationTime (timeval). What I don't have is the timebase for these timestamps.

From what I can tell, the timebase / time_scale of the timestamps provided by Live555 must be available somewhere for me to set it to my decoder. If it's not in the SPS description, how can I retrieve it?
