* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | 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.

* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01
| | | | They are not properly namespaced and not intended for public use.
* avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channelsHendrik Leppkes2020-12-10
| | | | | | | | | | | | 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 81503ac58a763a36b1f57264013b1e76acb62b68, which requires a valid channel count for decoders which do not set this capability.

* avcodec/mpegaudiodsp: Make initializing synth windows thread-safeAndreas Rheinhardt2020-11-24
| | | | | | | | | | These arrays are used by the Musepack decoders, the MPEG audio decoders as well as qdm2 and up until now, these arrays might be initialized more than once, leading to potential data races as well as unnecessary initializations. Therefore this commit ensures that each array will only be initialized once. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

Increases binary size for hardcoded tables by about 12 kB, which is about 15 kB from qdm2_table minus data and code saved that was only used for creating it.
