James Almer	b6627a57f4	Revert "avcodec/mpeg12dec: Do not alter avctx->rc_buffer_size" This reverts commit `eb88ccb92e`. AVCodecContext fields are the proper place for a decoder to export such values. This change is in preparation for the following commits.	1 year ago

Nuo Mi	25ecc94d58	avutil: add thread executor 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.

Lynne	11e22730e1	lavu/tx: add real to real and real to imaginary RDFT transforms 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.	1 year ago

Zhao Zhili	ff094f5ebb	avutil/channel_layout: make pre-defined channel layouts C++ friendly 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>	1 year ago

Anton Khirnov	acde0ae6c7	doc/ffmpeg: fix -enc_time_base documentation 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	1 year ago
Anton Khirnov	dff3a283cd	fftools/ffmpeg: rework -enc_time_base handling 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'.	1 year ago
Anton Khirnov	f264204de9	lavc: deprecate AV_CODEC_FLAG_DROPCHANGED 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	1 year ago

Devin Heitmueller	ac4247270c	avdevice/decklink_enc: add support for SMPTE 2038 VANC packet output 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.
