Andreas Rheinhardt	1d66a122df	avcodec/avcodec: Deprecate AV_INPUT_BUFFER_MIN_SIZE It used to be used with preallocated packet buffers with the old encode API, but said API is no more and therefore there is no reason for this to be public any more. So deprecate it and use an internal replacement for the encoders using it as an upper bound for the size of their headers.

Anton Khirnov	75697836b1	Require compilers to support C11. It should be available in all relevant modern compilers and will allow us to use features like anonymous unions. Note that stdatomic.h is still emulated on MSVC, as current versions require the /experimental:c11atomics, and do not support ATOMIC_VAR_INIT() anyway.	9 months ago

James Almer	ec2036454b	avformat: add a disposition field to AVStreamGroup The existing (and upcoming) available group types are meant to combine several streams for presentation, with the result being treated as if it was a stream itself. For example, a file could export two stream groups of the same type with one of them as the "default". Signed-off-by: James Almer <jamrial@gmail.com>	9 months ago

Anton Khirnov	aa3cfd4b5a	lavc/bsf: add a showinfo filter Analogous to the (a)showinfo lavfi filters, logs basic packet information. Mainly useful for debugging/testing/development.	10 months ago
Anton Khirnov	70ecb8238c	lavd: deprecate the bktr device It implements BSD-specific support for very old analog capture cards, which are highly unlikely to be useful today. After being added in 2005, there were never any commits to it beyond compilation fixes and generic maintenance. There have also been zero trac tickets for this device, and the only related web search result I found concludes that it does not work. The code also does some unacceptable things, like messing with signal handlers and storing its state in global variables.	10 months ago

Marth64	3525544e48	libavformat: add RCWT closed caption muxex Signed-off-by: Marth64 <marth64@proxyid.net> Raw Captions With Time (RCWT) is a format native to ccextractor, a commonly used open source tool for processing 608/708 closed caption (CC) sources. It can be used to archive the original, raw CC bitstream and to produce a source file file for later CC processing or conversion. As a result, it also allows for interopability with ccextractor for processing CC data extracted via ffmpeg. The format is simple to parse and can be used to retain all lines and variants of CC. A free specification of RCWT can be found here: https://github.com/CCExtractor/ccextractor/blob/master/docs/BINARY_FILE_FORMAT.TXT This muxer implements the specification as of 01/05/2024, which has been stable and unchanged for 10 years as of this writing. This muxer will have some nuances from the way that ccextractor muxes RCWT. No compatibility issues when processing the output with ccextractor have been observed as a result of this so far, but mileage may vary and outputs will not be a bit-exact match. Specifically, the differences are: (1) This muxer will identify as "FF" as the writing program identifier, so as to be honest about the output's origin. (2) ffmpeg's MPEG-1/2, H264, HEVC, etc. decoders extract closed captioning data differently than ccextractor from embedded SEI/user data. For example, DVD captioning bytes will be translated to ATSC A53 format. This allows ffmpeg to handle 608/708 in a consistant way downstream. This is a lossless conversion and the meaningful data is retained. (3) This muxer will not alter the extracted data except to remove invalid packets in between valid CC blocks. On the other hand, ccextractor will by default remove mid-stream padding, and add padding at the end of the stream (in order to convey the end time of the source video).	10 months ago

Niklas Haas	5e751dabc5	doc/APIchanges: document newly added buffersrc field This was accidentally removed in a prior revision of the series, alongside the corresponding (separate) version bump.
