[ffmpeg-vaapi][vp8 decode] almost all vp8 decode test cases failed when using ffmpeg-vaapi #190

I think same as the issue #57 |
|
even after merging #86 still have some issue, ffmpeg create 2 context, register reference surface 0-15 to context 0, register reference surface 16-31 to context 1, after decode first frame to surface 15, it call vaDestoryContext to destroy context 0 and continue to decode another frame with context1. still use 15 as the reference. it is an invalid reference frame. |
when the count in VABoolCoderContextVPX is zero, actually it means there are 8 bit in bool coder correct first partition_size,when there is 8 bits in bool coder Signed-off-by: XinfengZhang <carl.zhang@intel.com>
The fix is to align changes in driver and in libmfx, that improve use of bitcount and 1st partition size computation. No more special code for count==8. Proper partition size is assumed. Instead of intel#239. To be merged the same moment with Intel-Media-SDK/MediaSDK#493 Issue: intel#190
correct first partition_size,macroblock offset is 8 aligned Signed-off-by: XinfengZhang <carl.zhang@intel.com>

Is this still an issue? I can't reproduce on today's mainline stack. |
|
I test with mainline branch at tag/n4.1 , not all avc vp8 decode fail now. These are 43 failed cases in 2054 cases. |
|
Yes, I'm seeing a lot of failures on my end now. Not sure what changed. |

and others
These test cases can work on intel-vaapi-driver
