MPEG-4 video rtp payloader
Locked
 
|
Does anyone knows which plugin can be used as a payloader for raw
mpeg4( simple profile ) video ? I tried the rtpmp4vpay,but it does not work. My pipeline is the following : sender : gst-lanuch -v filesrc location="test.mpeg4" ! rtpmp4vpay ! udpsink port=5000 receiver : gst-lanuch -v udpsrc port=5000 ! rtpmp4vdepay ! filesink location=out.mpeg4 When I run the sender , it pops the following messages and then breaks down. -------------------------------------------------------------------------------------- Setting pipeline to PAUSED ...

It won't parse a raw bitstream for you. So, you need to have a parser before it (e.g. mpeg4videoparse), since it's coming from a file (rather than an encoder, which would already output parsed buffers, with appropriate caps).

Hi, Mike
Thanks for your reply. I tried this pipeline : gst-lanuch -v filesrc location="test.mpeg4" ! mpeg4videoparse ! rtpmp4vpay ! udpsink port=5000 But it stops after pops the following message: ----------------------------------------------------------------------- Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ----------------------------------------------------------------------- It does not pop more messages , no warnings and errors. Could you give me some advice ?

Are you 100% sure it's a raw mpeg4 video file ? And not in a container format ? Use gst-typefind-0.10 on that file to see the type of the file. If it's in a container format, you'll need to use the appropriate demuxer before the mpeg4video parser.

Yes. I am sure.
Actually, I get the mpeg4 file from a avi demuxer. Also , I tried files directly saved from the output of a hardware mpeg4 encoder( in a SOC , like TI's DM355 processor ).
