Subject: [gst-devel] Problem in gstrtpbin and AV Transfer---Urgent
Hi All..
I am facing some other problem in RTP Streaming...
I am sending the rtp data over the UDP and playing it on the other end.
I am recording the data from v4l2src @ 10 fps and voice data from
alsasrc to send it across. The transmission starts well as well as i can
see the video on the other end.
Now in between i starts to take the data from a file.
I decode the data and encode again to send it using the same rtpbin and
udpsink.
Enc, Pay gstrtpbin and udpsink are the element kept common...means i
will use these elements in both the cases.
the packets goes well and on the other end i can see the AV fine in both
the cases....
Now when i again switch back to v4l2src the packets on the receiver end
come but the decoder (ffdec_mpeg4) gives error.......and there is no
updates on display........
The file i am using is @25fps......
also when i increase the FPS of v4l2src the whole system works
well.....@20 fps.....
Please let me know if i am missing something or i am doing something
wrong way....
Also i tried using different enc and pay elements in both the case..but
i i unlink and link to gstrtpbin, there is no data at all..even in the
first switch to file transfer.............. :(
Please help...i have tried every possible thing to fix this issue....but
i am stuck with the same for last couple of days now.....
Any input will be appreciated from bottum of heart.......

The receiver needs the sampling, width, height and configuration
strings. Run the sender pipeline with -v, then copy the caps on the RTP
udpsink to the receiver udpsrc caps (and yes, they are huge and they are
needed).
