Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs 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.

Anton Khirnov	e15371061d	lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bump They are not properly namespaced and not intended for public use.	4 years ago
Hendrik Leppkes	494f868e93	avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channels 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 `81503ac58a`, which requires a valid channel count for decoders which do not set this capability. Signed-off-by: Hendrik Leppkes <h.leppkes@gmail.com>	4 years ago
Andreas Rheinhardt	35f61eb350	avcodec/nellymoserdec: Make decoder init-threadsafe Easy now that initializing the ff_sine_* tables is thread-safe. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	55c7bb0665	avcodec/nellymoserdec: Don't use invalid AVPacketSideDataType Commits `957a593cd9` and `11828b8885` made the flv demuxer export a certain flag as side data to be used by the nellymoser decoder for mid-stream sample rate changes. It used a custom side data type 'F' that was never officially documented. Yet since `2215c39e94` (merged in commit `52c522c720`) this information is exported via the properly documented AV_PKT_DATA_PARAM_CHANGE side data. The merge commit therefore stopped exporting the 'F' sidedata; yet the changes in the Nellymoser decoder (which are now dead code (and would become dangerous if lots of new side data types were added)) have not been removed. This commit does this. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	5 years ago

Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
