Hi.
I am using VLC (using a sdp file) to play a UDP stream from
gstreamer. It is a MPEG4 640x480 30FPS video. But the VLC shows me an “avcodec
error: more than 5 seconds of late video -> dropping frame (computer too
slow ?)” and displays only a few frames. I streamed the video to a file
via VLC to find that the headers are incorrect, though the video frames are
correct. Using gstreamer (udpsrc), I do get the correct headers and the frames.
So, I think there is a problem with my SDP file. Can someone
help me identify the problem?????
Host pipeline: appsrc is-live=true name=source caps=”video/mpeg,
mpegversion=(int)4, framerate=(fraction)1001/30000, width=(int)640,
height=(int)480" ! rtpmp4vpay send-config=TRUE ! udpsink
host=172.24.136.232 port=5000
Caps for udpsink are: application/x-rtp,
media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP4V-ES,
profile-level-id=(string)0,
config=(string)000001010000012000845d4c28a021e0a21f, payload=(int)96,
ssrc=(guint)1737447791, clock-base=(guint)408271081, seqnum-base=(guint)50199
My SDP file is as below:
v=0
s=Session streamed with GStreamer
i=live
t=0 0
a=tool:Gstreamer
m=video 5000 RTP/AVP 96
b=RR:0
c=IN IP4 172.24.136.232
a=rtpmap:96 MP4V-ES/90000
a=fmtp:96 profile-level-id=0;
config=000001010000012000845d4c28a021e0a21f
a=cliprect:0,0,480,640
a=framesize:96 640-480
a=type:broadcast
a=tool:Gstreamer
Thanks in advance.
Regards,
Neel.
