* avcodec/hevcpred: Pass HEVCLocalContext when slice-threadingAndreas Rheinhardt2022-07-251-4/+4
| | | | | | | | | | | | | | | | | The HEVC decoder has both HEVCContext and HEVCLocalContext structures. The latter is supposed to be the structure containing the per-slicethread state. Yet that is not how it is handled in practice: Each HEVCLocalContext has a unique HEVCContext allocated for it and each of these coincides except in exactly one field: The corresponding HEVCLocalContext. This makes it possible to pass the HEVCContext everywhere where logically a HEVCLocalContext should be used. This commit stops doing this for lavc/hevcpred as well as the corresponding mips code; the latter is untested. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/hevcdec: constrained intra predict, do not check top left IS_INTRA ↵Xu Guangxin2020-10-281-1/+1
| | | | | | | | | | | | | | if it's not available fix ticket: 8932 For poc 2, we have tile boundary at x = 640. When we predict cu(640,912),the top left pixel is not avaliable to the cu. So, we can not check it's intra or not. We need set top[-1] = top[0] directly. see 8.4.4.2.1 for details Signed-off-by: Xu Guangxin <oddstone@gmail.com> Signed-off-by: Linjie Fu <linjie.justin.fu@gmail.com>
