Dear all,

I have the same problem.

It is not possible to publish an RTSP stream from an udpsrc without transcoding/reencoding the rtp source stream?

Best Regards,

Angel

Very late (and short) reply. I'm sorry I didn't remember that you were
using the rtsp server. Could you please post the debug log for the
