* aarch64/vvc: Bind h26x/sao filter implementation to vvcZhao Zhili2024-08-315-15/+48

* aarch64/hevc: Move sao to h26x directoryZhao Zhili2024-08-314-10/+39
| | | | | | So vvc can reuse the implementation. Reviewed-by: Martin Storsjö <[email protected]>
* lavc/vvc: Validate explicit subpic locationsFrank Plowman2024-08-311-11/+38
| | | | | | | | Implement the missing requirements from H.266 (V3) p. 106 on the position and size of subpictures whose dimensions are provided explicitly. Signed-off-by: Frank Plowman <[email protected]>
* lavc/vvc: Prevent OOB access in subpic_tilesFrank Plowman2024-08-311-2/+2
| | | | | | | | | | | | | | | | The previous logic relied on the subpicture boundaries coinciding with the tile boundaries. Per 6.3.1 of H.266 (V3), vertical subpicture boundaries are always tile boundaries however the same cannot be said for horizontal subpicture boundaries. Furthermore, it is possible to construct an illegal bitstream where vertical subpicture boundaries are not coincident with tile boundaries. In these cases, the condition of the while loop would never be satisfied resulting in an OOB read on col_bd/row_bd. Patch fixes this issue by replacing != with <, thereby not requiring subpicture boundaries and tile boundaries to be coincident. Signed-off-by: Frank Plowman <[email protected]>
