* avcodec: add AVCodecContext.frame_num as 64 bit variant to frame_numberMarton Balint2023-02-131-1/+1
| | | | | | | | | | Frame counters can overflow relatively easily (INT_MAX number of frames is slightly more than 1 year for 60 fps content), so make sure we use 64 bit values for them. Also deprecate the old 32 bit frame_number attribute. Signed-off-by: Marton Balint <cus@passwd.hu>
* lavc: support AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE in all no-delay encodersAnton Khirnov2023-01-291-1/+1
| | | | Including fake-delay encoders marked with FF_CODEC_CAP_EOF_FLUSH.
* avcodec/codec_internal: Avoid deprecation warnings for channel_layoutsAndreas Rheinhardt2022-09-281-5/+1
| | | | | | | | | | | | | | | | | | 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 Rheinhardt2022-09-031-1/+1
| | | | | | | | 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 Rheinhardt2022-07-181-1/+1
| | | | | | | | | | | 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 Rheinhardt2022-04-051-1/+1
| | | | | | | | | | | 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 Rheinhardt2022-03-211-11/+11
| | | | | | | | | | | | | | | | 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/[e]ac3enc: Allow user-supplied buffersAndreas Rheinhardt2021-05-051-0/+1
| | | | | | | | The size of the output buffer is always known in advance and the code has no alignment requirement (it uses mostly the PutBits API), so allowing user-supplied buffers is trivial. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-271-1/+1
| | | | | | | | | | 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/ac3enc: Share options and defaultsAndreas Rheinhardt2021-02-071-5/+2
| | | | | | | | | | Both AC-3 encoder share the same options, yet they are nevertheless duplicated in the binary; and the options applying to the EAC-3 encoder are a proper subset of the options for the AC-3 encoders, so that it can use the same options as the former by putting the options specific to AC-3 at the front. This commit implements this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/[e]ac3enc: Make encoders init-threadsafe, fix raceAndreas Rheinhardt2021-01-091-1/+1
| | | | | | | | | | | ff_eac3_exponent_init() set values twice when initializing a static table; ergo the initialization code must not run concurrently with a running EAC-3 encoder. Yet this code is executed every time an EAC-3 encoder is initialized. So use ff_thread_once() for this and also for a similar initialization performed for all AC-3 encoders to make them all init-threadsafe.

* avcodec/ac3enc_float, eac3enc: Fix leaks on init errorAndreas Rheinhardt2020-09-181-0/+1
| | | | | | | | | | | | | | | | | The AC-3 encoders (both floating- as well as fixed-point) as well as the EAC-3 encoder share code: All use ff_ac3_encode_init() as well as ff_ac3_encode_close(). Until ee726e777b851cdd4e28cdab36b38f0c39e35ea9 ff_ac3_encode_init() called ff_ac3_encode_close() to clean up on error. Said commit removed this and instead set the FF_CODEC_CAP_INIT_CLEANUP flag; but it did the latter only for the fixed-point AC-3 encoder and not for the other two users of ff_ac3_encode_init(). This caused any already allocated buffer to leak upon a subsequent error for the two other encoders. This commit fixes this by adding the FF_CODEC_CAP_INIT_CLEANUP flag to the other two encoders using ff_ac3_encode_init(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
