* avcodec: add AVCodecContext.frame_num as 64 bit variant to frame_numberMarton Balint2023-02-13
| | | | | | | | | | 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>

* avcodec/avcodec: Remove AV_CODEC_FLAG2_DROP_FRAME_TIMECODEAndreas Rheinhardt2023-02-09
| | | | | | | | | | It has been deprecated in 94d68a41fabb55dd8c7e59b88fe4a28a637d1e5f and can't be set via AVOptions. The only codecs that use it (the MPEG-1/2 encoders) have private options for this. So remove it.

* lavu/frame: deprecate reordered_opaqueAnton Khirnov2023-02-04
| | | | | It is only used in libavcodec, where it's been superseded by AV_CODEC_CAP_COPY_OPAQUE.
* lavc/decode: allow using AV_CODEC_FLAG_COPY_OPAQUE for decodingAnton Khirnov2023-02-04
| | | | | Use it to propagate AVPacket.opaque[_ref] to corresponding AVFrame fields. This is a more convenient alternative to reordered_opaque.
* lavc/encode: pass through frame durations to encoded packetsAnton Khirnov2023-01-29
| | | | | | The generic code can only handle the no-delay case. Encoders with delay need to be handled individually, which will be done in the following commits.
* lavc: add a codec flag for propagating opaque from frames to packetsAnton Khirnov2023-01-29
| | | | | | | | | This is intended to be a more convenient replacement for reordered_opaque. Add support for it in the two encoders that offer AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE: libx264 and libx265. Other encoders will be supported in future commits.
* lavc/avcodec: improve AV_CODEC_FLAG_RECON_FRAME doxyAnton Khirnov2023-01-29
| | | | | | Do not break a sentence on a period after "i.e.". Link to the definition of AV_CODEC_CAP_ENCODER_RECON_FRAME.

* avcodec/avcodec: Escape Doxygen referenceMarvin Scholz2022-10-17
| | | | | | The # is interpreted as explicit reference request by Doxygen which is not desired here, use markdown inline code to avoid that.
* avcodec: Fix Doxygen trailing brief commentsMarvin Scholz2022-10-17
| | | | | The //< comment is not any magic comment supported by Doxygen, instead use ///< to mark them as doc for the members.
* avcodec/avcodec: Deprecate lavc chroma pos API functionsAndreas Rheinhardt2022-09-26
| | | | | | | | | | | | avcodec_enum_to_chroma_pos() and avcodec_chroma_pos_to_enum() deal with enum AVChromaLocation which is defined in lavu. These functions are therefore replaced by av_chroma_location_enum_to_pos() and av_chroma_location_pos_to_enum(). This commit provides the necessary deprecations. Also already make these functions wrappers around the corresponding lavu functions as not doing so would force one to disable deprecation warnings.

* avcodec/avcodec: Move AV_ER_* and FF_COMPLIANCE_* to defs.hAndreas Rheinhardt2022-09-26
| | | | | | | | They are also frequently used in libavformat. This change does not cause any breakage as avcodec.h includes defs.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* lavc: fix and extend AVCodecContext.hwaccel_context doxyAnton Khirnov2022-09-06
| | | | | | | | | Mention: - that it is legacy and optional (every hwaccel that uses it can also work with hwcontext, though some optional information can only be signalled throught hwaccel_context) - that it can be used for encoders (only qsvenc currently) - ownership and lifetime

* lavc: add API for exporting reconstructed frames from encodersAnton Khirnov2022-08-02

* avcodec: add API for automatic handling of icc profilesNiklas Haas2022-07-30
| | | | | | | | | | | | | | | This functionally already exists, but as pointed out in #9672 and #9673, requiring users to manually include filters is clumsy, error-prone and hard to use together with tools like ffplay. To streamline ICC profile support, add a new AVCodecContext flag to globally enable reading and writing ICC profiles, automatically, for all appropriate media types. Note that this commit only includes the new API. The implementation is split off to separate commits for readability. Signed-off-by: Niklas Haas <git@haasn.dev>
* avcodec/avcodec: Don't mention removed functionAndreas Rheinhardt2022-06-30

* Keep including the full version.h when headers are included externallyMartin Storsjö2022-03-19
| | | | | | | | | This avoids unnecessary churn and build breakage for users, by making sure the whole version.h is included like it has been so far, while keeping the benefit of not needing to rebuild most files in the ffmpeg tree on minor/micro bumps. Signed-off-by: Martin Storsjö <martin@martin.st>
* libavcodec: Split version.hMartin Storsjö2022-03-16
| | | | | | | | | | | | | | This avoids including version.h in all source files, avoiding unnecessary rebuilds when the version number is bumped. Only version_major.h is included by the main header, which defines availability of e.g. FF_API_* macros, and which is bumped much less often. This isn't done for libavutil/version.h, because that header needs to be included essentially everywhere due to LIBAVUTIL_VERSION_INT being used wherever an AVClass is constructed.

* lavc: deprecate AV_CODEC_(FLAG|CAP)_TRUNCATEDAnton Khirnov2021-09-20
| | | | | | | | | | It is supported only by a few decoders (h263, h263p, mpeg(1|2|)video and mpeg4) and is entirely redundant with parsers. Furthermore, using it leads to missing frames, as flushing the decoder at the end does not work properly.
