Hi, i am new to VLC and i would like to do the following for start:
-write doen simple code to stream out media file via rtp protocol to specific location (like from command line)
Comand line for doing this is: vlc -v --loop file:///home/student/vlc-1.1.9/VlcIgranje/mission_impossible.ts :sout=#transcode\{vcodec=h264,vb=0,width=100,acodec=mp4a,ab=128,channels=2,samplerate=44100\}:rtp\{dst=192.168.3.63,port=6969,mux=ts\} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep
Please, write down some suggestions or post some useful links....

Hello,
I am interested in exactly the same thing. (I want to stream h264 encoded data from my c application, and not a file) Is there any documentation about the rtp module of lib vlc or something similar ?
I have seen the vlc/modules/rtp.c code, it is useful in a way, however, if there is some example or API that describes the basic components/calls needed would be really great.
Thank you very much.

Nobody has yet had time to write a proper API for streaming output. Same goes for the documentation of the (non-existent) API.

Thank you very much Rémi Denis-Courmont for your fast answer.
In anyway, is rtp.c and rtcp.c the proper place to look at, and try to implement in my code the streaming of raw 264 data? Or will I need something more?
And one other thing please, you use live 555 library just for the client side right? I mean vlc's implementation of server is different from live555's?
Thank you once more for your time.

I don't know. VLC only uses live555 on client side.

Hey sokrat3s, let me know if this code helps to you:
Code: Select all
char *vlcOptions[] = {""};
vlcInstance = libvlc_new(1, vlcOptions);
libvlc_vlm_add_broadcast(vlcInstance,
"test",
"file:///home/student/vlc-1.1.9/VlcIgranje/mission_impossible.ts", "#transcode{vcodec=h264,vb=0,width=100,acodec=mp4a,ab=128,channels=2,samplerate=44100\}:rtp\{dst=192.168.3.63,port=6969,mux=ts},dst=display}",
0,
NULL,
TRUE,
0);
libvlc_vlm_play_media(vlcInstance, "test");
Make sure to NOT put ":no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep" part.
