* avcodec/pixblockdsp: Improve 8 vs 16 bit checkAndreas Rheinhardt2025-05-311-17/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, the input in get_pixels and get_pixels_unaligned has been treated inconsistenly: - The generic code treated 9, 10, 12 and 14 bits as 16bit input (these bits correspond to what FFmpeg's dsputils supported), everything with <= 8 bits as 8 bit and everything else as 8 bit when used via AVDCT (which exposes these functions and purports to support up to 14 bits). - AARCH64, ARM, PPC and RISC-V, x86 ignore this AVDCT special case. - RISC-V also ignored the restriction to 9, 10, 12 and 14 for its 16bit check and treated everything > 8 bits as 16bit. - The mmi MIPS code treats everything as 8 bit when used via AVDCT (this is certainly broken); otherwise it checks for <= 8 bits. The msa MIPS code behaves like the generic code. This commit changes this to treat 9..16 bits as 16 bit input, everything else as 8 bit (the former because it makes sense, the latter to preserve the behaviour for external users*). *: The only internal user of AVDCT (the spp filter) always uses 8, 9 or 10 bits.

* avcodec/mpegvideo: Only keep the actually used unquantize funcsAndreas Rheinhardt2025-03-261-4/+5
| | | | | | | | | | | | | | 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/mpegvideoenc: Add MPVEncContextAndreas Rheinhardt2025-03-268-35/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the fields of MpegEncContext (which is also used by decoders) are actually only used by encoders. Therefore this commit adds a new encoder-only structure and moves all of the encoder-only fields to it except for those which require more explicit synchronisation between the main slice context and the other slice contexts. This synchronisation is currently mainly provided by ff_update_thread_context() which simply copies most of the main slice context over the other slice contexts. Fields which are moved to the new MPVEncContext no longer participate in this (which is desired, because it is horrible and for the fields b) below wasteful) which means that some fields can only be moved when explicit synchronisation code is added in later commits. More explicitly, this commit moves the following fields: a) Fields not copied by ff_update_duplicate_context(): dct_error_sum and dct_count; the former does not need synchronisation, the latter is synchronised in merge_context_after_encode(). b) Fields which do not change after initialisation (these fields could also be put into MPVMainEncContext at the cost of an indirection to access them): lambda_table, adaptive_quant, {luma,chroma}_elim_threshold, new_pic, fdsp, mpvencdsp, pdsp, {p,b_forw,b_back,b_bidir_forw,b_bidir_back,b_direct,b_field}_mv_table, [pb]_field_select_table, mb_{type,var,mean}, mc_mb_var, {min,max}_qcoeff, {inter,intra}_quant_bias, ac_esc_length, the *_vlc_length fields, the q_{intra,inter,chroma_intra}_matrix{,16}, dct_offset, mb_info, mjpeg_ctx, rtp_mode, rtp_payload_size, encode_mb, all function pointers, mpv_flags, quantizer_noise_shaping, frame_reconstruction_bitfield, error_rate and intra_penalty. c) Fields which are already (re)set explicitly: The PutBitContexts pb, tex_pb, pb2; dquant, skipdct, encoding_error, the statistics fields {mv,i_tex,p_tex,misc,last}_bits and i_count; last_mv_dir, esc_pos (reset when writing the header). d) Fields which are only used by encoders not supporting slice threading for which synchronisation doesn't matter: esc3_level_length and the remaining mb_info fields. e) coded_score: This field is only really used when FF_MPV_FLAG_CBP_RD is set (which implies trellis) and even then it is only used for non-intra blocks. For these blocks dct_quantize_trellis_c() either sets coded_score[n] or returns a last_non_zero value of -1 in which case coded_score will be reset in encode_mb_internal(). Therefore no old values are ever used. The MotionEstContext has not been moved yet. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* aacdec: remove AAC-specific MIPS optimizationsLynne2024-04-238-3466/+1

* avcodec/aacdec: Use same AACDecContext for fixed and floatAndreas Rheinhardt2024-04-231-3/+3
| | | | | | | | | | | | | | | | | | Up until now, there was one AACDecContext for the fixed and one for the floating point decoder. These differed mostly in certain arrays which were int for the fixed-point and float for the floating point decoder; there were also differences in corresponding function pointers. Yet in order to deduplicate the enormous amount of currently duplicated code between the float and the fixed-point decoder, one needs common contexts. Given that int and float have the same size on all common systems, this commit replaces these arrays by unions of int arrays and of float arrays. The names of these arrays have been chosen to be compatible with AAC_RENAME(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/aacsbr: Make ff_aac_sbr_* funcs accept ChannelElement*Andreas Rheinhardt2024-04-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | Each ChannelElement contains exactly one SpectralBandReplication structure; the latter structure contains lots of buffers whose size depend upon USE_FIXED (i.e. AAC_FLOAT arrays). This complicates deduplicating the parts of the AAC decoder that are duplicated between the fixed-point and the floating point decoder. In order to fix this, the SpectralBandReplication structure will be moved from the part of ChannelElement visible to the common code. Therefore the ff_aac_sbr_* functions are ported to accept a ChannelElement*; they will then have to translate that to the corresponding SpectralBandReplication* themselves (which is possible, because there are floating-point and fixed-point versions of these functions). While just at it, also ensure that these functions are properly namespaced. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/mips/aaccoder_mips: Remove MIPS-specific aaccoderAndreas Rheinhardt2024-03-182-2504/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ff_aac_coder_init_mips() modifies a static const structure of function pointers. This will crash if the binary uses relro and is a data race in any case. Furthermore it points to a maintainability issue: The AACCoefficientsEncoder structures have been constified in commit fd9212f2edfe9b107c3c08ba2df5fd2cba5ab9e3, a Libav commit merged in 318778de9ebec276cb9dfc65509231ca56590d13. Libav did not have the MIPS-specific AAC code and so this was fine for them; yet FFmpeg had them, but this was not recognized. Commit 75a099fc734a4ee2b1347d0a3d8c53d883b95174 points to another maintainability issue: Contrary to ordinary DSP code, this code here is way more complex and needs to be constantly kept in sync with the ordinary code which it mimicks and replaces. Said commit is the only commit actually changing aaccoder.c in the last few years and the same change has not been performed for the MIPS clone; before that, it even happened several times that the mips code was broken due to changes of the generic code (see commits 97437bd17a8c5d4135b2f3b1b299bd7bb72ce02c and de262d018d7d7d9c967af1dfd1b861c4b9eb2a60 or 860dbe0275e57cbf4228f3f653f872ff66ca596b or 933309a6ca0f18bf1d40e917fff455221f57fb4b or b65ffa316e377213c29736929beba584d0d80d7c). This might even lead to scenarios where someone changing non-dsp aacenc code would have to modify mips inline asm in order to keep them in sync. This is obviously a significant burden (if the AAC encoder were actively developed). Finally, the code does not even compile here due to errors like "Error: float register should be even, was 1".

| | | | | | | | | | | | Otherwise aacenc.o gets pulled in by the aacencdsp checkasm test and it in turn pulls the rest of lavc in. Besides being bad size-wise this also has the downside that it pulls in avpriv_(cga|vga16)_font from libavutil which are marked as being imported from another library when building libavcodec as a DLL and this breaks checkasm because it links both lavc and lavu statically.
