Description Liu Tienan 2013-05-06 06:38:58 UTC
System Environment:
----------------------------------------
Platform: IVB
Libva: staging branch 2b25c3439781f0b7162011627a8ad3bb6288d1bb
Intel-driver: staging branch 5bd630d4ea732818728b0a464f45739c86e08be3
Gst-vaapi: 0.4 branch dd40042d447a0b696a75172bd3ed6cd1bad23377


Reproduce steps:
---------------------------------
1.  xinit&

###  change container  ###
2.  gst-launch-0.10 filesrc location=/home/gst-media/Stream/Sally.ts ! tsdemux ! vaapidecode ! vaapiencodeh264 rate-control=cqp init-qp=26 intra-period=30 b-frame-num=2 ! qtmux faststart=true ! filesink location=enc.mp4

###  dump yuv file  ###
3.  ffmpeg -i /home/gst-media/Stream/Sally.ts source.yuv
4.  ffmpeg -i enc.mp4 enc.yuv
