Hi, I am interested in streaming H264 contents over RTP using VLC through the GUI. But looks like the module is not enabled ( stream_out_rtp ) by default. Is there a way to enable it?
I downloaded the source code and compiled it on my redhad linux machine. The VLC I am running is build locally. I am using H264 transport stream file as the source and trying to stream RTP out. I added some debug messages in the rtp.c file (rtp_packetize_264 function) but seems the code is not getting accessed during the process. Would someone help me on this issue? Is there a special flag I should turn on or I can only use command line? (if so, would someone provide the command line ?)

Heyy Avc,
i personally dont know how to activate that rtp packetizer function, but i can certainly say VLC can play back elementary stream H264 RTP streams..i'm doing so myself right now from my custom streamer..DJ should be able to help you out; in the mean time, try to look at the source code and see if you can trace back that packetizer function call

If I use vlc H264.mpg --sout '#rtp{dst=xx.xx.xx.xx port=1234 mux=ts}' the function rtp_packetize_h264 can get invoked but looks like the stream only sends out to port 1232 which don't have a valid ip address.

If I use vlc h264.mpg --sout '#rtp{dst=xx.xx.xx.xx,port=1234}' then function rtp_packetize_h264 can not get invoked.

I am trying to dig through the code to figure out the correct command line parameters but could someone give me a clue??

Now I have the code from vlc/trunk. I used vlc -vv h265.mpg '#rtp{dst=10.0.0.1,port=1234,ttl=1000}' to create the streams. On the output messages, I saw lots of "access_output_udp private warning: send error: Connection refused" message.

I then used ethereal trying to catch the traffic and see streams being sent out to 10.0.0.1:1230 and 10.0.0.1:1232 and also there are lots of ICMP packets.

Anyone knows what are those and why?

Which command you were using to let VLC receiving H264 over RTP?

Thanks

Looks like no one can give me some suggestions on what to do.. anyway, I keep posting my progress and hope it will help some new commers...

After I specified the port_video and port_audio, the connection refused message is less.

Here are my problems.
1. When I use VLC to listen to the input stream using UDP/RTP on the video port, the messages say garbage input...
2. I captured the stream packets and decoded them as RTP. I found that the timestamps are the same value ( no matter what ). The sequence number is increasing as excepted...

The H264 content I am using can be played on VLC and can be streamed out as TS stream to another VLC....

Any ideas.. suggestions..

Well I have to make vlc as a VOD server and use rtsp from vlc client to get the H264 over RTP working. Is there a way that can can catch live H264 streams and stream it out using H264/RTP ?
