* avcodec/aacdec: Use same AACDecContext for fixed and floatAndreas Rheinhardt2024-04-231-2/+2
| | | | | | | | | | | | | | | | | | 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 Rheinhardt2024-04-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | 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>

* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-311-0/+1
| | | | | | | | | | | There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/aacdec: Rename AACContext to AACDecContextAndreas Rheinhardt2024-02-271-5/+5
| | | | | | | | | | It is decoder-only; furthermore, there is already an AACContext in use by libfdk-aacenc.

* aacdec: convert to lavu/tx and support fixed-point 960-sample decodingLynne2022-11-061-3/+1
| | | | | | | | | | | 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/codec_internal: Avoid deprecation warnings for channel_layoutsAndreas Rheinhardt2022-09-281-6/+2
| | | | | | | | | | | | | | | | | | AVCodec.channel_layouts is deprecated and Clang (unlike GCC) warns when setting this field in a codec definition. Fortunately, Clang (unlike GCC) allows to use FF_DISABLE_DEPRECATION_WARNINGS inside a definition (of an FFCodec), so that one can create simple macros to set AVCodec.channel_layouts that also suppress deprecation warnings for Clang. (Notice that some of the codec definitions were already inside FF_DISABLE/ENABLE_DEPRECATION_WARNINGS (that were not guarded by FF_API_OLD_CHANNEL_LAYOUT); these have been removed. Also notice that setting AVCodec.channel_layouts was not guarded by FF_API_OLD_CHANNEL_LAYOUT either, so testing disabling it it without removing all the codeblocks would not have worked.)

* avcodec/codec_internal: Add macro to set AVCodec.long_nameAndreas Rheinhardt2022-09-031-2/+2
| | | | | | | | It reduces typing: Before this patch, there were 105 codecs whose long_name-definition exceeded the 80 char line length limit. Now there are only nine of them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-181-2/+2
| | | | | | | | | | | and remove FF_CODEC_CAP_INIT_THREADSAFE All our native codecs are already init-threadsafe (only wrappers for external libraries and hwaccels are typically not marked as init-threadsafe yet), so it is only natural for this to also be the default state.

* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-051-2/+2
| | | | | | | | | | | This is possible, because every given FFCodec has to implement exactly one of these. Doing so decreases sizeof(FFCodec) and therefore decreases the size of the binary. Notice that in case of position-independent code the decrease is in .data.rel.ro, so that this translates to decreased memory consumption.

* avcodec/codec_internal: Make FFCodec.decode use AVFrame*Andreas Rheinhardt2022-04-051-1/+1
| | | | | | | | This increases type-safety by avoiding conversions from/through void*. It also avoids the boilerplate "AVFrame *frame = data;" line for non-subtitle decoders. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-211-21/+21
| | | | | | | | | | | | | | | | Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

* avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.hAndreas Rheinhardt2022-03-211-1/+1
| | | | | | | | | | Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault. This reduces the amount of files that have to include internal.h (which comes with quite a lot of indirect inclusions), as e.g. most encoders don't need it. It is furthemore in preparation for moving the private part of AVCodec out of the public codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | Since the removal of the 16-bit FFT said define is unnecessary as FFT_FIXED_32 is always !FFT_FLOAT. But one wouldn't believe it when looking at the code. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-271-2/+2
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* avcodec/aacdec, aactab: Move kbd tables to their only userAndreas Rheinhardt2020-12-081-0/+2
| | | | | | | | | | | | The floating point kbd tables for 120 and 960 samples are only used by the floating point decoder whereas the fixed point kbd tables for 128 and 1024 samples are only used by the fixed point AAC decoder. So move these tables to their only users. This ensures that they are not accidentally used somewhere else without ensuring that initializing these tables stays thread-safe (as it is now because the only place from where they are initialized is guarded by an AVOnce).

* avcodec/aacdec, sinewin: Move 120 and 960 point sine tables to aacdecAndreas Rheinhardt2020-12-081-0/+3
| | | | | | | | | | | | | The floating point AAC decoder is the only user of these tables, so it makes sense to move them there. Furthermore, initializing the ordinary power-of-two sinetables is currently not thread-safe and if the 120- and 960-point sinetables were not moved, one would have to choose whether to guard initializing these two tables with their own AVOnces or not. Doing so would add unnecessary AVOnces as the AAC decoder already guards initializing its static data by an AVOnce; not doing so would be fragile if a second user of these tables were to be added.
