Mark Thompson	a3c8fba5da	apv_decode: Multisymbol entropy decode	2025-05-13 19:37:49 +01:00
Mark Thompson	2aa2095bb4	cbs_apv: Better constrain tile_width/height_in_mbs ... The maximum number of tile columns/rows adds an extra constraint on the minimum tile width/height for large frames (over 5120 width or 2560 height).	2025-05-05 17:22:57 +01:00
Mark Thompson	1a9a2bafc8	apv_decode: Improve reporting of decode errors ... Halt tile component decoding at the first entropy error (this will be a desync and is not recoverable). If any tile components contain errors then discard the frame unless the output-corrupt flag is set. Also fixes CID 1646764, which is the error case where the tile component is too large for get_bits to handle.	2025-05-05 17:22:57 +01:00

James Almer	a9557c1f26	avcodec/apv_decode: build the lut table only once ... No reason to build the exact same table once per decoding thread. Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: James Almer <jamrial@gmail.com>	2025-05-05 13:19:29 -03:00
Mark Thompson	585455f7b3	apv_decode: Replace division with shift ... The compiler can't see that this should be a shift and generates a real division which is slow enough to appear in profiles on its own.	2025-04-30 22:57:56 +01:00
Andreas Rheinhardt	fcc562693e	avcodec/apv_decode: Remove redundant log message ... ff_thread_get_buffer() already emits its own logmessage. Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2025-04-27 23:00:10 +02:00
