* avformat: Constify all muxer/demuxersAndreas Rheinhardt2021-04-27
| | | | | | | This is possible now that the next-API is gone. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> Signed-off-by: James Almer <jamrial@gmail.com>
* avisynth: fix audio on big endianStephen Hutchinson2021-03-11
| | | | | | | | AviSynth+ outputs audio in the same format as the OS, so assuming little endian formats as input on big endian OSes results in nothing but static. Signed-off-by: Stephen Hutchinson <qyot27@gmail.com>

* avisynth: more intelligent RGB flippingStephen Hutchinson2021-03-11
| | | | | | | | avs_is_color_space provides a generic way of checking whether the video is RGB, and has been available through AVSC_API since 2.6. This means that GetProcAddress doesn't have to run on every frame. Signed-off-by: Stephen Hutchinson <qyot27@gmail.com>

* avformat/avisynth: switch to AviSynth+ on LinuxStephen Hutchinson2020-04-05
| | | | | | | | | | AviSynth+ now supports non-Windows OSes, making AvxSynth obsolete. Since we no longer support AviSynth 2.5 (which is essentially what AvxSynth is), remove AvxSynth support and replace it with AviSynth+. As a result, the USING_AVISYNTH defines can be switched back to generic _WIN32.
* avformat: Forward errors where possibleAndreas Rheinhardt2019-12-12
| | | | | | | | | | 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.

* avisynth: adapt 239d02eff3ffe9f7d40caa21dde50fb4a0e94c24 to dlsymStephen Hutchinson2019-05-04
| | | | | | | | This commit was merged in a couple years ago as a no-op because we had already switched from GetProcAddress to dlsym some time before that. However, not applying the actual cast causes warnings about FARPROC and when attempting to build FFmpeg in MSVC with AviSynth-GCC 32-bit compatibility, those FARPROC warnings turn into FARPROC errors.
* libavformat/avisynth: enable additional pix_fmtsStephen Hutchinson2019-05-04
| | | | | | | These pix_fmts have been added to FFmpeg in the 31 months since commit 92916e8542e425ca20daddb490261a5818643206 added support for the larger number of pix_fmts that AviSynth+ can use. They were present in AviSynth+ even then, just not in libavutil.
* lavc, lavf: move avformat static mutex from avcodec to avformatwm42017-12-26
| | | | | | | | It's completely absurd that libavcodec would care about libavformat locking, but it was there because the lock manager was in libavcodec. This is more stright forward. Changes ABI, but we don't require ABI compatibility currently.

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
