* Handle AVID MJPEG streams directly in the MJPEG decoder.Anton Khirnov2021-02-25
| | | | | | | | | | | | | | | | | | | | AVID streams - currently handled by the AVRN decoder - can be (depending on extradata contents) either MJPEG or raw video. To decode the MJPEG variant, the AVRN decoder currently instantiates a MJPEG decoder internally and forwards decoded frames to the caller (possibly after cropping them). This is suboptimal, because the AVRN decoder does not forward all the features of the internal MJPEG decoder, such as direct rendering. Handling such forwarding in a full and generic manner would be quite hard, so it is simpler to just handle those streams in the MJPEG decoder directly. The AVRN decoder, which now handles only the raw streams, can now be marked as supporting direct rendering. This also removes the last remaining internal use of the obsolete decoding API.

* pngdec: fix and simplify apng reference handlingAnton Khirnov2021-02-24
| | | | | | | | | Current code is very confused and confusing. It uses two different reference frames - "previous" and "last" - when only one is really necessary. It also confuses the two, leading to incorrect output with APNG_DISPOSE_OP_PREVIOUS mode. Fixes #9017.
* lavc/lscrdec: drop unapplicable private capabilitiesAnton Khirnov2021-02-24
| | | | | | | FF_CODEC_CAP_ALLOCATE_PROGRESS makes no sense because the decoder does not support frame threading. FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM makes no sense because the decoder does not handle skip_frame.
* lavc: split LSCR decoder out of PNG decoderAnton Khirnov2021-02-24
| | | | | It shares very little code with pngdec, so keeping them together only makes the code harder to read.

* avutil/buffer: free all pooled buffers immediately after uninitializing the poolJames Almer2021-02-24
| | | | | | | | | | | | | No buffer will be fetched from the pool after it's uninitialized, so there's no benefit from waiting until every single buffer has been returned to it before freeing them all. This should free some memory in certain scenarios, which can be beneficial in low memory systems. Based on a patch by Jonas Karlman.

* avcodec/bitstream: Rewrite code to avoid triggering compiler warningAndreas Rheinhardt2021-02-24
| | | | | | | | | | | | | Clang infers from the existence of a default case that said case can be taken. In case of libavcodec/bitstream.c said default case consisted of an av_assert1 that evaluates to nothing in case of the ordinary assert level. In this case (that doesn't happen) a variable wouldn't be initialized, so Clang emitted Wsometimes-uninitialized warnings. Solve this by making sure that the default path also initializes the aforementioned variable.

| | | | | | | | | | | | | | Commit 0d1229f1d2b8f26dd50c6be7917bb8ed8cb95364 factored the main part of the voc demuxer's read_packet function out; yet when this Libav commit was merged in f99195d56f4aab266926724ca1cfae822df4df16, the dependency of the other users of this function on vocdec.o was unnecessarily kept. This commit fixes this. While just at it, also disable the data only used by the voc demuxer and muxer in voc.c if both of them are disabled.
