[gst-devel] rtspsrc plugin: udpsrc Internal data flow error

[Aurelien Grimaud]

Are you sure sample_100kbit.mp4 is h264 ?
seems like a qtss sample and mine is mpeg4 ....
try rtpmp4vdepay and ffdec_mpeg4.
You should gst-launch with -v option, it will hint you about video codec.
Caps on rtspsrc video src pad is 'application/x-rtp, media=video, 
encoding-name=MP4V-ES'
