Streaming out live H264 problem

Postby AvcRtp » 17 Nov 2006 00:59

I tried to use VLC 0.8.6 test-2 as a VOD to stream out live H264 streams using the telnet command line using input udp:@:1234. I have a H264 stream targeted to that port. VLC will only find two es streams if running under gdb, but will only find one es stream when running along (which causes only audio stream get send out for rtsp requests.. )

hello AVC,
i dont think anyone here is willing to help for some reason..someone should know the answer to ur question! either way, my hunch is VLC doesn't support RTP streaming of h264 out...so what i suggest to you is to write your own RTSP Server implementation for h264 - i did it in about a week and its not too difficult

if you follow the RTP 3984 spec (only do FU-A framing and single NAL unit mode), and the JVT-G050 spec doc, you'll be golden!

Actually I managed to make H264 over RTP working. Used ethereal to catch the traffic and also put some debuging message on the code rtp_packetize_h264 ( which claimed as the support of rfc3894. ). The trick is that you have to use vlc as a VOD server (open telnet interface and rtsp server, which you can find how to do it from document.) and then use rtsp from another vlc to trigger the rtp packetize. ( all because H264 over rtp sends out two streams to client .... ).

The current problem I have is on the vlc VOD side. I have a live H264 TS stream sends to the listened udp port of vlc, the 0.8.6 code tries to demux the input stream. But the problem is that if the ts demuxer finds the PID in PMT as h264 first, everything works.. but if the ts demuxer finds the PID in PMT a mpeg stream, it then terminates the demux too fast ( set EOF and control type = 0 ) which on the rtsp request, it treats the stream as a mpeg and only sends out audio to the desired port !!!.

I am now trying to figure out how to solve the problem ( if no one helps )....
Attached is the log, the first one is the good analysis and the second one is the bug!
