Need Help to run my plugin

Hi All,

I have installed gstreamer-0.10.25 and gstreamer-base-plugins-0.10.25. And i have tested following video testsrc plugins.

gst-launch-0.10 -v videotestsrc ! ffmpegcolorspace ! ximagesink and it is working fine.

I have develop following 2 plugins and i want to get display from my video decoder. I am using following pipe line.

gst-launch-0.10 filesrc location=~/test.m4v ! yuv ! mpeg4dec ! ffmpegcolorspace ! ximagesink

Here yuv plugin will read raw data from filesrc and push raw data to mpeg4decelement. Mpeg4dec element decode raw data and genearte yuv data and same will be pushed to ffmpegcolorspace element. When i run that pipeline it gives me following error.

space
Setting pipeline to PAUSED ...
Width = 320 Height = 240
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
(MPEG4DEC) Memory is not allocated
!!Caught SIGSEGV accessing address 0x10
Killed

My plugons capabilities are as followed.

[ ] gst-inspect-0.10 yuv is as followed.

Please help me to resolve this issue. If i am wrong at any place please correct me. I am using by default setcaps and getcaps function which we are generating from gst-template-master source code.

-Thanks In Advance,

Tejas.

what about using mpeg4videoparse instead of your own "yuv" element?
