RTPbin

Hi ppl,
Wanted your help on an application using rtpbin. The question i have is that when u request a recv_rtp_sink_%d pad, there is supposed to be a recv_rtp_src_%d_%d_%d pad to be formed automatically.
I want to link this pad to a decodebin but i have no idea where can i get a refernce to this pad.
Can anyone help...

Re: RTPbin

You can connect to a pad-added signal, when this pad gets added, you'll be notified.

Hope this helps :)

Re: RTPbin

Rahul,

You can just create a “sink” pad for your decodebin.

Then link them in “pad-added” signal.

Re: RTPbin

In reply to this post by sreejesh-2

Guys i have got the pipeline to work. So i am fetching the udp rtp src using rtpbin and udpsrc decoding it thru a decodebin and then streaming it on an rtsp src.
the problem that i am getting now is that after the first frame the thing gets hanged up but the pipeline is still running.

Re: RTPbin

Aren't you forgetting to put queue elements after the demuxer output pads?

Re: RTPbin

Hey Guys,
I have got the pipeline working and the data is flowing properly. Thanx a lot for ur quick response.
Now one issue that i am getting is that there's a slight problem with the lip sync. The audio is delayed by a fraction of a second relative to the video which is kind of noticeable.
I am fetching the RTP streams from a live rtp source.
Any idea as to what can be causing this to happen.
