[FFmpeg-devel] [PATCH v1] avcodec/av1dec: Add tile list OBU to decompose list

[fei.w.wang-at-intel.com@ffmpeg.org]

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

Show the unsupported message and return unsupported for clips contain
tile list OBU since it hasn't been implemented. Otherwise, decoding
maybe successful but result is incorrect.
