Comment 1 Luca Ognibene 2005-09-17 11:48:56 UTC

I've tried with current 0.8 cvs and gstreamer doesn't segfault. It displays a
weird video but doesn't segfault :)
I've tried mplayer and xine and they segfaults. Are you able to play this video
with some video player? 

thanks!

Comment 2 Wouter Bolsterlee (uws) 2005-09-17 19:16:28 UTC

mplayer plays the file just fine over here

Comment 3 Luca Ognibene 2005-09-17 19:39:25 UTC

ok, i can play it with mplayer -vo x11 but not with xvideo.
This pipeline also works:
gst-launch-0.8 filesrc location="movie.mpeg" ! decodebin ! ffmpegcolorspace !
ximagesink
but this show garbage:
gst-launch-0.8 filesrc location="movie.mpeg" ! decodebin ! ffmpegcolorspace !
xvimagesink

Can you confirm? Are you using xvideo with mplayer?

Comment 4 Luca Ognibene 2005-09-18 08:06:22 UTC

It seems to be the same issue as #314897 (if you're not using xvideo with mplayer..)

Comment 5 Luca Ognibene 2005-09-20 20:06:05 UTC

Marking as duplicate of #314897. Please reopen if mplayer with xvideo works
fine. thanks for reporting the bug!
