* avcodec/cbs_av1: add a range check to tg_endJames Almer2020-11-113-2/+8
| | | | | | | | | | | Section 6.10.1 of the AV1 spec states: It is a requirement of bitstream conformance that the value of tg_start is equal to the value of TileNum at the point that tile_group_obu is invoked. It is a requirement of bitstream conformance that the value of tg_end is greater than or equal to tg_start. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/gdv: Remove dead checkAndreas Rheinhardt2020-11-101-1/+1
| | | | | | | | | | | | | At the end of its decode function, the decoder sets *got_frame to 1 and then checks whether ret is < 0; if so, it is returned, otherwise avpkt->size is. But it is impossible for ret to be < 0 here and if it were, it would be nonsense to set *got_frame to 1 before this. Therefore just return avpkt->size unconditionally. Fixes Coverity issue #1439730.

* avcodec/cllc: Don't unnecessarily free VLCAndreas Rheinhardt2020-10-291-8/+3
| | | | | | | | | | | The Canopus Lossless decoder uses several VLCs and if initializing the ith VLC fails, all the VLCs 0..i have been freed; the ith VLC's table is initialized to NULL for this purpose. Yet it is totally unnecessary to free the ith VLC table at all: ff_init_vlc_sparse() cleans up after itself on error and if an error happens before ff_init_vlc_sparse(), the ith VLC hasn't been touched yet and doesn't need freeing.
