Back to January 2014, I reported under Driver 3345 release notes this post:
The post says that for this http://www.sendspace.com/file/06p3gb 3D VC-1 clip with a 2880 x 1080 resolution, the DXVA VC1_VLD2010 device decoder produced artifacts.
All the other decoders (VC1_VLD_ClearVideo, VC1_VLD_2_ClearVideo, WMV9_IDCT, VC1_IDCT) are working just fine up to 4K.
The workaround from Intel was to disable 4K support of VC1_VLD2010 and to limit decoding up to 1080p in the next driver release of Driver 3412 as I wrote back then: (take a look in number 3)
The problem is that even latest driver 3621 hasn't resolved that issue and VC1_VLD2010 decoder is still limited up to 1080p, while all the other Vc-1/WMV9 decoders go up to 4K.
The question is:
Do you think this bug is fixable ?
Is there an ETA of this fix ?
