If multiple (‘slice’) NAL units make up a single frame (picture), then the
presentation times are supposed t

What I observe is that the NAL units used for a single decoded frame have
different presentation times. In that case I don't know which time to use
for the given frame.

Hi Ross,
Thanks for your reply.
Indeed I am using Live555 as the RTSP client side, and I'm able to connect
and receive the NAL units and the sps-pps information from the camera.
Maybe you're right and my issue is completely on the decoding side, as I'm

Unfortunately your question wasn’t particularly clear.
Could you clarify exactly how you are using the “LIVE555 Streaming Media”
software? Are you developing a RTSP client application (e.g., similar to
So,
I found that as I'm using RTP, a clock rate of 9Hz must be used. In
some cases cameras specify a different clock rate... but if none is
specified I should be using that one.
My problem now, is that I do get timestamps for the NAL units, but I
don't know the timestamp of my decoded fr
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 n
