* avformat/wvdec: Export version as extradataAndreas Rheinhardt2020-04-021-0/+3
| | | | | | | | | It might be used by the Matroska muxer. This is also the reason why the FATE-tests for muxing WavPack into Matroska needed to be updated: They now write the correct version 4.07 and not 4.03 as before.

* avcodec/wavpack: add support for DSD filesDavid Bryant2020-03-111-11/+17
| | | | | | | | | | | | | | | | | 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).

* avformat: Remove unnecessary av_packet_unref()Andreas Rheinhardt2020-02-101-4/+0
| | | | | | | | | Since bae8844e the packet will always be unreferenced when a demuxer returns an error, so that a lot of calls to av_packet_unref() in lots of demuxers are now redundant and can be removed.

* avformat: Forward errors where possibleAndreas Rheinhardt2019-12-121-2/+2
| | | | | | | | | | It is not uncommon to find code where the caller thinks to know better what the return value should be than the callee. E.g. something like "if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit changes several instances of this to instead forward the actual error.

| * lavf: fix usage of AVIOContext.seekableAnton Khirnov2016-09-301-2/+2
| | | | | | | | | | | | | | | | It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-231-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.
