Using udpsrc as source in rtsp-server

[Krzysztof Konopko]

Hi Damiano,

I guess you need to get rid of quotes around the caps value in your
REALTIME stream pipeline. They are required on the command line and get
consumed by the shell when constructing argument list.

Try replacing

"
caps=\"application/x-rtp,media=(string)video,encoding-name=(string)H264\" !"

with

" caps=application/x-rtp,media=(string)video,encoding-name=(string)H264 !"

HTH,
Kris
