* avcodec/mediacodecenc: use bsf to handle cropZhao Zhili2022-12-17
| | | | | | | It's well known that mediacodec encoder requires 16x16 alignment. Use our bsf to fix the crop info. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>

* configure: Add (h264|hevc)_sei subsystemsAndreas Rheinhardt2022-12-01
| | | | | | | | | | | | | | | | | | Currently, several components select atsc_a53, despite not using anything from it themselves. They only select it because parsing SEI messages adds an indirect dependency. But using direct dependencies is more natural, so add dedicated subsystems for them. It already allows to remove a superfluous dependency of the HEVC QSV encoder on hevc_sei and atsc_a53. Adding new subsystems only becomes effective after a reconfiguration. In order to force this, some needed headers (which are only included implicitly before this commit) were included explicitly in libavformat/allformats.c.

| | | | | | | | added a new option 'a53cc' (on by default, as in libx264) for rendering AV_FRAME_DATA_A53_CC as hevc sei payloads. the code is a blend of the libx265.c code for writing AV_FRAME_DATA_SEI_UNREGISTERED with the libx264.c code for writing atsc a/53 payloads.

* avcodec/vc1dec: Remove VC-1 decoders->H.263 decoder dependencyAndreas Rheinhardt2022-11-06
| | | | | | | | | | | | | | The only thing from the H.263 decoder that is reachable by the VC-1 decoder is ff_h263_decode_init(); but it does not even use all of it; e.g. h263dsp is unused and so are the VLCs initialized in ff_h263_decode_init() (they amount to about 77KB which are now no longer touched). Notice that one could also call ff_idctdsp_init() directly instead of ff_mpv_idct_init(); one could even do so in ff_vc1_init_common().

* avcodec/vc1dec: Split VC-1 decoders from msmpeg4Andreas Rheinhardt2022-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only msmpeg4 code that is ever executed by the VC-1 based decoders is ff_msmpeg4_decode_init() and what is directly reachable from it. This is: a) A call to av_image_check_size(), then ff_h263_decode_init(), b) followed by setting [yc]_dc_scale_table and initializing scantable/permutations. c) Afterwards, some static tables are initialized. d) Finally, slice_height is set. The replacement for ff_msmpeg4_decode_init() performs a) just like now; it also sets [yc]_dc_scale_table, but it only initializes inter_scantable and intra_scantable and not permutated_intra_[hv]_scantable: The latter are only used inside decode_mb callbacks which are only called in ff_h263_decode_frame() which is unused for VC-1.* The static tables initialized in c) are not used at all by VC-1 (the ones that are used have been factored out in previous commits); this avoids touching 327KiB of .bss. slice_height is also not used by the VC-1 decoder (setting it in ff_msmpeg4_decode_init() is probably redundant after b34397b4cd780b5692548e7d021ec884c7217dba). *: It follows from this that the VC-1 decoder is not really based upon the H.263 decoder either; changing this will be done in a future commit.

* aacdec: convert to lavu/tx and support fixed-point 960-sample decodingLynne2022-11-06
| | | | | | | | | | | This patch replaces the transform used in AAC with lavu/tx and removes the limitation on only being able to decode 960-sample files with the float decoder. This commit also removes a whole bunch of unnecessary and slow lifting steps the decoder did to compensate for the poor accuracy of the old integer transformation code. Overall float decoder speedup on Zen 3 for 64kbps: 32%

* avcodec/nvenc: add AV1 encoding supportTimo Rothenpieler2022-11-05
| | | | | | | | | | | | | | | | The encoder seems to be trading blows with hevc_nvenc. In terms of quality at low bitrate cbr settings, it seems to outperform it even. It produces fewer artifacts and the ones it does produce are less jarring to my perception. At higher bitrates I had a hard time finding differences between the two encoders in terms of subjective visual quality. Using the 'slow' preset, av1_nvenc outperformed hevc_nvenc in terms of encoding speed by 75% to 100% while performing above tests. Needless to say, it always massively outperformed h264_nvenc in terms of quality for a given bitrate, while also being slightly faster.

Somehow it was nevertheless used to simply apply the identity permutation on ff_zigzag_direct. This commit stops doing so. It also renames perm to scantable, because it is only the scantable as given by the spec without any further permutation performed by us.
