[FFmpeg-devel] [PATCH v3 2/2] lavc/hevcdec: Update slice index before hwaccel decode slice

[fei.w.wang at intel.com]

From: Fei Wang <fei.w.wang at intel.com>

Otherwise, slice index will never update for hwaccel decode, and slice
RPL will be always overlap into first one which use slice index to construct.

Fixes hwaccel decoding after 47d34ba7fbb81
