Comment 1 haihao 2013-11-26 02:08:46 UTC 
sgb doesn't support MPEG-2 encoding
Comment 2 Shuang He 2013-11-26 02:24:58 UTC 
Haihao, you're misunderstanding the purpose of this bug report.
If sandybridge doesn't support MPEG2 encoding, vainfo/libva/intel-driver should be fixed to not report this capability
This bug is used to drive this
Comment 3 haihao 2013-11-26 02:40:08 UTC 
Oh, this is an 'old' bug,  I thought it has been fixed :(
