hi,

I get udpsrc warnings in the videowall project :

Start server 1st:
gst-launch filesrc location=./mpeg1.mpg ! mpegparse ! udpsink

Then the client:
gst-launch udpsrc ! { queue ! mpegdemux } ! { queue ! mpeg2dec ! 
ffcolorspace ! xvimagesink }

I get these error messages :
GStreamer-CRITICAL **: file gstcaps.c: line 517 (gst_caps_is_fixed): 
assertion `caps != NULL' failed
GStreamer-WARNING **: trying to set non fixed caps on pad udpsrc:src, not 
allowed

Mpeg1 files read okay, though.

With mpeg2, I get an extra error :

** (process:1777): CRITICAL **: file xvimagesink.c: line 403
(gst_xvimagesink_xwindow_clear): assertion `xwindow != NULL' failed

With mpeg2 files, I have to start the server before the client if I want 
to see the picture. If I start the server after the client, I get a black 
window screen (it resizes to the size of the video though).

I don't know if this xvimagesink error is realated with the udpsrc problem.

Best regards,
Alex CONRAD
