[Libva] [PATCH V3 2/2] Add multi quality levels encoding support for GEN7

2014-06-10 Thread Zhong Li
Two encoding quality levels are support on GEN7. Default quality level is set to be 1, which has better quality, but higher gpu usage and worse performance. The second quality level is set to be 2, which has lower gpu usage and better performance,but worse quality. Other platforms support for multi

2014-06-10 Thread Zhong Li
Add two encoding quality levels configurable for GEN7 v1->v2: merge vme relative patches together. v2->v3: 1. follow haihao's comments to init and check quality_level. 2. remove CBR limitation for low quality level encoding. Zhong Li (2): Add old version vme shaders Add multi quality

[Libva] H264 decoder erroneous output, some bytes off-by-one

2014-06-10 Thread Sam Jansen
Hi all, I've been working on H264 encode, decode, and JPEG decode VA-API programs recently, using the Intel va-driver on Sandy Bridge and Bay Trail. This has gone well, but I've hit a problem with the H264 decoder in some situations where I believe it is producing incorrect output. In some cases
