* avcodec/mpegvideo: Add missing headersAndreas Rheinhardt2025-07-031-1/+1
| | | | | | | These files currently rely on implicit inclusions of avassert.h and/or mathops.h via get_bits.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo: Only keep the actually used unquantize funcsAndreas Rheinhardt2025-03-261-2/+2
| | | | | | | | | | | | | | For all encoders and all decoders except MPEG-4 the unquantize functions to use don't change at all and therefore needn't be kept in the context. So discard them after setting them; for MPEG-4, the functions get assigned on a per-frame basis. Decoders not using any unquantize functions (H.261, MPEG-1/2) as well as decoders that only call ff_mpv_reconstruct_mb() through error resilience (RV30/40, the VC-1 family) don't have the remaining pointers set at all.

* avcodec/mpegvideo: Move unquantize functions into a file of their ownAndreas Rheinhardt2025-03-261-0/+1
| | | | | | | This is in preparation for only keeping the actually used unquantize functions in MpegEncContext. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo: remove redundant workaround to recalculate last nonzero ↵Ramiro Polla2024-09-031-4/+2
| | | | | | | | | | | | | | | | | coefficient The x86 optimized dct_quantize only calculates the last nonzero coefficient correctly if the zigzag scan order is used. For the alternate scan order, this value is incorrect. To work around this, the dct_unquantize functions process the entire block if the alternate scan order is used. But a second workaround (bb198e198ab) was added that recalculates the last nonzero coefficient after dct_quantize is called if the alternate scan order is used. This commit removes the first workaround, which became redundant.
