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 ...
