* avcodec/pcm: Avoid AVCodec.sample_fmts for decodersAndreas Rheinhardt2025-03-171-12/+37
| | | | | | | | These fields are meant to be for encoders; just use a local table in pcm_decode_init() to convert from AVCodecID to AVSampleFormat and also use it to provide sample_size. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/pcm: Remove always-false checkAndreas Rheinhardt2025-03-171-6/+0
| | | | | | | | | | | All codecs here have a valid sample size at this point. This check has (presumably) been added for DVD PCM, but even for them the check was always-true after 381e195b46d080aee1d9b05ef2b6b140e9463519 (and the DVD code was later moved out altogether). So just remove this check and the leftover DVD comment. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal, all: Use macros to set deprecated AVCodec fieldsAndreas Rheinhardt2025-03-101-4/+2
| | | | | | | | | | | | | | The aim of this is twofold: a) Clang warns when setting a deprecated field in a definition and because several of the widely set AVCodec fields are deprecated, one gets several hundred warnings from Clang for an ordinary build. Yet fortunately Clang (unlike GCC) allows to disable deprecation warnings inside a definition, so that one can create simple macros to set these fields that also suppress deprecation warnings for Clang. This has already been done in fdff1b9cbfd8cf5a9810c29efa4baf13a4786742 for AVCodec.channel_layouts. b) Using macros will allow to easily migrate these fields to internal ones.

* 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>

| | | | Including fake-delay encoders marked with FF_CODEC_CAP_EOF_FLUSH.
* avcodec/pcm: Remove always-false checkAndreas Rheinhardt2022-09-221-5/+0
| | | | | | | | None of the decoders here have the AV_CODEC_CAP_CHANNEL_CONF set, so that it is already checked generically that the number of channels is positive. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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/internal: Move ff_get_buffer() to decode.hAndreas Rheinhardt2022-08-271-2/+1

* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-181-2/+0
| | | | | | | | | | | 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 Rheinhardt2022-04-051-3/+2

* avcodec/mathops: Move bitswap_32() to its only userAndreas Rheinhardt2022-03-211-0/+1

* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-211-14/+14
| | | | | | | | | | | | | | | | 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 Rheinhardt2022-03-211-0/+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>

* 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.

| * Gather all coded_frame allocations and free functions to a single placeVittorio Giovara2015-07-201-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
