Description zhixinx.liu 2014-05-21 07:51:58 UTC 
no regression fail, there are some error message when doing transcoder test. Does the testing gstreamer pipe line right?
or there are some issue in gstreamer vaapi.

1. Testing Env:
========================================================================
kernel:	3.15.0-rc3_drm-intel-fixes_e95a2f_20140520
X11R7:	X11R7.stable.2014-05-20

2. Testing Steps:
========================================================================
1.running following command to start transcoder test
	command: gst-launch-1.0 filesrc location=/home/MP4_h264_nHD_30FPS_580Kbps_AAC_44.1KHz_64Kbps_10sec0.7Mb_BBB-300.MP4 ! qtdemux ! vaapidecode !  vaapiencode_h264 rate-control=cbr bitrate=1000 keyframe-period=30 max-bframes=2 cabac=true ! qtmux faststart=true ! filesink location=/home/enc10.mp4

Comment 1 Gwenole Beauchesne 2014-06-17 15:32:41 UTC 
The gstreamer-vaapi pipeline looks correct. I built the exact same with another source video, and it just worked right.

Make sure you haven't mixed any GStreamer 1.0 and GStreamer 1.2 elements around, i.e. make sure you exclusively use 1.2 on your system for instance. Does this still occur for you? On what platform?
Comment 2 zhixinx.liu 2014-07-03 07:55:08 UTC 
cannot reproduce this issue with gstreamer 1.2, so close it.
