* avformat/daudenc: force 2000 sample packet size with a bsfMarton Balint2024-03-14
| | | | | | | | The samples I found all have 2000 sample packets, and by forcing the packet size with a bsf we could automagically make muxing work for packets containing more than 3640 samples. Signed-off-by: Marton Balint <cus@passwd.hu>

* avcodec/vdpau: Deprecate redundant allocators and getter/setterAndreas Rheinhardt2024-03-08
| | | | | | | | | | | The allocators have been superseded by av_vdpau_bind_context(). The latter have only been added "to allow multiple forks to add fields to the structure without breaking ABI" [1], but libav is no more, so this is not needed any longer.

* avformat/wavdec: dynamically set max_size by defaultMarton Balint2024-03-02
| | | | | | | | | | | | | The wav demuxer by default tried to demux 4096-byte packets which caused packets with very few number of samples for files with high channel count. This caused a significant overhead especially since the latest ffmpeg.c threading changes. So let's use a similar approach for selecting audio frame size which is already used in the PCM demuxer, which is to read 25 times per second but at most 1024 samples.

* avcodec/bsf/mp3_header_decompress: Remove BSFAndreas Rheinhardt2024-03-02
| | | | | | | | | | | | | | | | | This BSF is supposed to be used in conjunction with mp3_header_compress, which has been removed more than ten years ago in commit c6080d89009056530119ab794ad02e4d515c7754. It mangled the headers by removing the CRC field as well as fields that are supposed to stay constant for the entirety of a stream (which are put into extradata). This made these files unplayable; they need to be decompressed with the BSF first (which does not happen automatically). Even in this case the CRC does not get restored. I am not aware that such compressed files exist at all; therefore this commit removes the BSF completely.

* avformat/mov: add support for tile HEIF still imagesJames Almer2024-02-26
| | | | | | | | | | | | Export each tile as its own stream, and the grid information as a Stream Group of type TILE_GRID. This also enables exporting other stream items like thumbnails, which may be present in non tiled HEIF images too. For those, the primary stream will be tagged with the default disposition.

* avcodec/avcodec: Deprecate AV_INPUT_BUFFER_MIN_SIZEAndreas Rheinhardt2024-02-21
| | | | | | | | | | | 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. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* Require compilers to support C11.Anton Khirnov2024-02-18
| | | | | | | | | 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.

* avformat: add a disposition field to AVStreamGroupJames Almer2024-02-13
| | | | | | | | | | 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.

* lavd: deprecate the bktr deviceAnton Khirnov2024-02-02
| | | | | | | | | | | | 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.
