Queue2 and RTP

[Daniel DEDISSE]

I want to create a pipeline of a RTP receiving stream with a ring buffer. Be able to seek and replay in the ring buffer.
I've modified the queue2 element to do that. It's working with a UDPSRC (mpegts stream) source but not with RTP.

The problem here should be that this will try to buffer the stream on-disk in a ringbuffer (ringbuffer-max-size). And this will not work properly for RTP.

What are you trying to do there?
