* 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>
