[Live-devel] A bug of h264 rtp packet's timestamp

[Ross Finlayson]

No, there's no bug here.  If there's no frame rate specified in the SPS NAL unit (or if no SPS NAL unit is present), then the "H264VideoStreamFramer" code (which reads from a continuous byte stream - e.g., from a file) has no possible way of knowing what frame rate to use.  In this case, it has to just 'guess' a frame rate.

If your stream does not specify a frame rate (in SPS NAL units), then you should not use the "H264VideoStreamFramer" class at all.  (However, if your stream consists of discrete NAL units (i.e., one at a time), then you should use the "H264VideoStreamDiscreteFramer" class instead.  In this case, the frame rate is determined automatically from the rate of arrival of source NAL units.)
