Issues with rtpmp2tpay

Hello,

I am currently having issues with some gstreamer code that I inherited from a colleague who has moved onto greener pastures. Specifically, I am having issues with implementing RTP.

The following pipeline works and sends the required packets over UDP multicast. Note that my syntax may or may not be exact since I do not have the code in front of me at the moment.

appsrc ! video/x-mpegts ! udpsink host=<MULTICAST ADDRESS> port=<port>

Here is the RTP pipeline that is causing the issue. Namely, I get the not-linked (-1) error for the appsrc.

appsrc ! video/x-mpegts ! rtpmp2tpay ! udpsink host=<MULTICAST ADDRESS> port=<port>

Note that the only difference is the addition of the rtmp2tpay element. Any thoughts as to why this does not work?

Thanks in advance for the help.

Re: Issues with rtpmp2tpay

The caps are incorrect. It should be video/mpegts not video/x-mpegts. You'll need to change your src pad caps from your appsrc. udpsink accepts any caps which is why that worked but not rtpmp2tpay.
