------- Comment #7 from ye haomiao  2008-08-22 02:42 UTC -------
sorry, this is the first time that I used this tool, I don't know how to delete
the patch and edit the description again, so I can only add comments now.

1. I build version gst-omx 0.10.0.4 failed, so I worked on 0.10.0.3. I used
Bellagio OpenMAX IL implementation for libomxil-B-0.3.3 (0.3.9 build failed)

2. I try to use qtdemux and gst-omx dec to play an mp4 failed
   gst-launch-0.10 filesrc location=./1m=.mp4 ! qtdemux ! omx_mpeg4dec !
ffmpegcolorspace ! videoscale ! ximagesink
   it report picture size failed (0, 0, (nil))
   found the resean is qtdemux add codec_data in caps, but omx_mpeg4dec did not
sent it to decoder, so I add the codec data in the first buffer and sent it
with the first frame, it can play now.

3. I'am not from the gst-omx team, so I don't know if there is better methods
to resolve this problem, and I don't know if how it works on TI hardware, so I
add this property to maintain the old behaviors.

4. Changed files:
   gstomx_base_filter.c
   gstomx_base_filter.h
   gstomx_base_videodec.c (this files change is same with 0.10.0.4)

Motorola would like to contribute Gstreamer patch to the Gstreamer open source
community project. Please find attached the patch applicable for Gstreamer. For
any questions, please feel free to contact ("Zhao Liang "e3423c at motorola.com",
