    H.264: Support Constrained Baseline profile instead of Baseline profile

    GENx doesn't support FMO/ASO, so remove the support
    of Baseline profile for conformance testing. In addition, add the suppo
    for Constrained Baseline profile.

Comment 1 haihao 2013-12-23 00:40:25 UTC 
Is it a decoding issue or encoding issue ? According to the title, it is an encoding issue, however according to the description in comment #1,  it is a decoding issue.
Comment 2 haihao 2013-12-23 00:45:38 UTC 
Genx supports Constrained Baseline profile instead of Baseline profile, so the patch mentioned at comment #1 is needed.  gstreamer vaapie should not use baseline profile for encoding/decoding on Genx.
Comment 3 zhenxiang.li 2013-12-23 00:51:14 UTC 
It's an decoding bug, sorry for my carelessness
Comment 4 haihao 2013-12-23 01:26:32 UTC 
Hi, Feng

Could you take a look at this issue ? 

Thanks
Haihao

profile of this video is Baseline. since driver updates and only support constrained baseline, the baseline profile supports were removed from gst-vaapi. that means some conformance tests would be failed.
