* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-18
| | | | | | | | | | | 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 Rheinhardt2022-04-05
| | | | | | | | | | | 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: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | 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 Rheinhardt2022-03-21
| | | | | | | | | | 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/golomb: Factor writing golomb codes outAndreas Rheinhardt2022-01-06
| | | | | | | | Most users only want to either read or write golomb codes, not both. By splitting these headers one avoids having unnecesssary (get|put)_hits.h inclusions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/flacenc: Avoid copying packet data, allow user-supplied buffersAndreas Rheinhardt2021-05-23
| | | | | | | | | The FLAC encoder calculates the size in advance, so one can avoid an intermediate buffer for the packet data by using ff_get_encode_buffer() and also set AV_CODEC_CAP_DR1 at the same time.

* avcodec: Remove redundant freeing of extradata of encodersAndreas Rheinhardt2021-04-28
| | | | | | | | AVCodecContext.extradata is freed generically by libavcodec for encoders, so it is unnecessary for an encoder to do it on its own. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Fixes ticket #4628. The problem arose, in the sample file at least, in the last block where the minimum and maximum Rice partition orders were both 0. In that case, and any other where pmax == pmin, the original UINT32_MAX placeholder value for bits[opt_porder] was getting overwritten before the comparison to check if the current partition order is a new optimal, so the correct partition order and RiceContext params were not being set.
