* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channelsHendrik Leppkes2020-12-10
| | | | | | | | | | | | The decoders in this set either have a fixed channel count, or read it from the bitstream, and thus do not require the channel count as external information. Fixes various regressions since 81503ac58a763a36b1f57264013b1e76acb62b68, which requires a valid channel count for decoders which do not set this capability.

* pthread_frame: merge the functionality for normal decoder init and ↵Anton Khirnov2020-04-10
| | | | | | | | | | | | | | | | init_thread_copy The current design, where - proper init is called for the first per-thread context - first thread's private data is copied into private data for all the other threads - a "fixup" function is called for all the other threads to e.g. allocate dynamically allocated data is very fragile and hard to follow, so it is abandoned. Instead, the same init function is used to init each per-thread context. Where necessary, AVCodecInternal.is_copy can be used to differentiate between the first thread and the other ones (e.g. for decoding the extradata just once).
* lavc: replace AVCodecInternal.allocate_progress with an internal capAnton Khirnov2020-04-10
| | | | This is a constant codec property, so a capability flag is more appropriate.
* wavpack: fully support stream parameter changesAnton Khirnov2020-04-10

* avcodec/wavpack: add support for DSD filesDavid Bryant2020-03-11
| | | | | | | | | | | | | | | | | Add support for WavPack DSD files to the existing WavPack decoder using avcodec/dsd to perform the 8:1 decimation to 32-bit float samples. We must serialize the dsd2pcm operation (cross-boundary filtering) but would like to use frame-level multithreading for the CPU-intensive DSD decompression, and this is accomplished with ff_thread_report/await_progress(). Because the dsd2pcm operation is independent across channels we use slice-based multithreading for that part. Also a few things were removed from the existing WavPack decoder that weren't being used (primarily the SavedContext stuff) and the WavPack demuxer was enhanced to correctly determine the sampling rate of DSD files (and of course to no longer reject them).
