* avcodec/defs: Add AV_PROFILE_* defines, deprecate FF_PROFILE_* definesAndreas Rheinhardt2023-09-071-0/+4
| | | | | | | | | These defines are also used in other contexts than just AVCodecContext ones, e.g. in libavformat. Furthermore, given that these defines are public, the AV-prefix is the right one, so deprecate (and not just move) the FF-macros. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* Revert "avcodec/mpeg12dec: Do not alter avctx->rc_buffer_size"James Almer2023-09-061-0/+3
| | | | | | | This reverts commit eb88ccb92e05018b1060cf8126b30eeeff551d3b. AVCodecContext fields are the proper place for a decoder to export such values. This change is in preparation for the following commits.
* avformat/rtmpproto: support enhanced rtmpSteven Liu2023-09-051-0/+7
| | | | | | | | add option named rtmp_enhanced_codec, it would support hvc1,av01,vp09 now, the fourcc is using Array of strings. Signed-off-by: Steven Liu <lq@chinaffmpeg.org>

* avutil: add thread executorNuo Mi2023-09-021-0/+3
| | | | | | | | | | The executor design pattern was introduced by java <https://docs.oracle.com/en/java/javase/20/docs/api/java.base/java/util/concurrent/Executor.html> it also adapted by python <https://docs.python.org/3/library/concurrent.futures.html> Compared to handcrafted thread pool management, it greatly simplifies the thread code.

* lavc/avfft: deprecate the APILynne2023-09-011-0/+5
| | | | This deprecates the currently unused API.
* lavu/tx: add real to real and real to imaginary RDFT transformsLynne2023-09-011-0/+3
| | | | | | | These are in-place transforms, required for DCT-I and DST-I. Templated as the mod2 variant requires minor modifications, and is required specifically for DCT-I/DST-I.
* lavfi/vf_libplacebo: add extra_opts AVDictionaryNiklas Haas2023-08-271-0/+10
| | | | | | Can be used to configure libplacebo's underlying raw options, which sometimes includes new or advanced / in-depth settings not (yet) exposed by vf_libplacebo.

* avutil/channel_layout: make pre-defined channel layouts C++ friendlyZhao Zhili2023-08-181-0/+3
| | | | | | | | | | | | C++ doesn't support designated initializers until C++20. We have a bunch of pre-defined channel layouts, the gains to make them usable in C++ exceed the losses. Bump minor version so C++ project can check before use these defines. Also initialize .opaque field explicitly to reduce warning in C++. Signed-off-by: James Almer <jamrial@gmail.com>

| | | | | | | | | The commits eac4324bfbe452f0292b48b2f1dc37b5052ec0be and cd8211527efbb9cad19db1c0d033da0749836e43 renamed the examples, but the targets were not updated.

| | | | Rewrite EOF logic while here.
* doc/ffmpeg: fix -enc_time_base documentationAnton Khirnov2023-07-151-4/+3
| | | | | | Stop claiming the argument is always a floating point number, which * confuses floating point and decimal numbers * is not always true even accounting for the above point
* fftools/ffmpeg: rework -enc_time_base handlingAnton Khirnov2023-07-151-3/+4
| | | | | | | | | Read the timebase from FrameData rather than the input stream. This should fix #10393 and generally be more reliable. Replace the use of '-1' to indicate demuxing timebase with the string 'demux'. Also allow to request filter timebase with '-enc_time_base filter'.
* lavc: deprecate AV_CODEC_FLAG_DROPCHANGEDAnton Khirnov2023-07-151-0/+3
| | | | | | | | This decoding flag makes decoders drop all frames after a parameter change, but what exactly constitutes a parameter change is not well defined and will typically depend on the exact use case. This functionality then does not belong in libavcodec, but rather in user code
* avfilter/avf_showcwt: add rotation optionPaul B Mahol2023-07-131-0/+7
|
* tests/fate-run: add testing with a random number of threadsAnton Khirnov2023-07-111-0/+8
| | | | | | | | Useful for discovering bugs that depend on a specific thread count. Use like THREADS=randomX for a random thread count from 1 to X, with X=16 when not specified. Note that the thread count is different for every test.

* lavfi/vf_libplacebo: add contrast recovery optionsNiklas Haas2023-07-081-0/+13
| | | | | New upstream option. Enabled by default in the high-quality preset upstream, so enable it by default here.
* lavfi/vf_libplacebo: deprecate hybrid_mix optionNiklas Haas2023-07-081-6/+0
| | | | Deprecated upstream in libplacebo v6.292.
* avutil/random_seed: add av_random_bytes()James Almer2023-07-051-0/+3
| | | | | | | Uses the existing code for av_get_random_seed() to return a buffer with cryptographically secure random data, or an error if none could be generated. Signed-off-by: James Almer <jamrial@gmail.com>
* avdevice/decklink_enc: add support for SMPTE 2038 VANC packet outputDevin Heitmueller2023-07-021-0/+5
| | | | | | | | | | | | | | | | | Support decoding and embedding VANC packets delivered via SMPTE 2038 into the SDI output. We leverage an intermediate queue because data packets are announced separately from video but we need to embed the data into the video frame when it is output. Note that this patch has some additional abstraction for data streams in general as opposed to just SMPTE 2038 packets. This is because subsequent patches will introduce support for other data codecs. Thanks to Marton Balint for review/feedback.
