* 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: Make FFCodec.decode use AVFrame*Andreas Rheinhardt2022-04-05
| | | | | | | | 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 Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | 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: 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.

* avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channelsHendrik Leppkes2020-12-10
| | | | | | | | | | | | The decoders in this set either have a fixed channel count, or read it from the bitstream, and thus do not require the channel count as external information. Fixes various regressions since 81503ac58a763a36b1f57264013b1e76acb62b68, which requires a valid channel count for decoders which do not set this capability.

* opus: add an option to toggle intensity stereo phase inversionRostislav Pehlivanov2017-12-04

* opus_celt: rename structures to better names and reorganize themRostislav Pehlivanov2017-02-14
| | | | | | | | | | | | | | | | | | | | This is meant to be applied on top of my previous patch which split PVQ into celt_pvq.c and made opus_celt.h Essentially nothing has been changed other than renaming CeltFrame to CeltBlock (CeltFrame had absolutely nothing at all to do with a frame) and CeltContext to CeltFrame. 3 variables have been put in CeltFrame as they make more sense there rather than being passed around as arguments. The coefficients have been moved to the CeltBlock structure (why the hell were they in CeltContext and not in CeltFrame??). Now the encoder would be able to use the exact context the decoder uses (plus a couple of extra fields in there). FATE passes, no slowdowns, etc. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
