* Remove unnecessary libavutil/(avutil|common|internal).h inclusionsAndreas Rheinhardt2022-02-241-1/+4
| | | | | | | | | | Some of these were made possible by moving several common macros to libavutil/macros.h. While just at it, also improve the other headers a bit. Reviewed-by: Martin Storsjö <martin@martin.st> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/wavpack: add support for DSD filesDavid Bryant2020-03-111-0/+2
| | | | | | | | | | | | | | | | | 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).
