Hi franco, I think the issue you are experimenting is more related to FFMPEG or LIBAV than Live555. I am trying achieve the same you are tyring to, however I don't have much time to dedicate to it. Up to now I am using the same approach you suggested (using the current system time in PTS == 0 and starting to increase it with PTS units) with some sort of success, however I don't like this hacky solution, I am pretty sure there is a better approach.
After digging a while I managed to find timing information in AVFormatContext struct of FFMPEG. Get the RTSPState from priv_data, then from there get the RTSPStream and then the RTPDemux. RTPDemuxContext structure has RTCP information and timestamps, I believe there you can find some sort of absolute timestamp. I hope it is useful, and I'd be pleased to know if you managed to solve it this way, as I am on the same way too ;) Regards, David 2016-03-08 14:25 GMT+01:00 Franco Miceli <fra...@radixcast.com>: > Hello, > > I have implemented a live streamer based on live555 and am using a > receiver based on libav. > > The live stream is received and played back correctly. > > My issue is that, although I set a time value to the presentation time > (fPresentationTime) in live555, the pts of the packet is always 0 when > I receive the packet with av_read_frame. > > Should I be setting fPresentationTime in some particuar way (using > getTimeOfDay now)? > Is there any way I can test this with the openRTSP player? > > Thanks for any help. > > Regards, > > -- > Eng.
