* avcodec/aptx: Use AVCodecContext.frame_size according to the APIAndreas Rheinhardt2022-09-191-9/+0
| | | | | | | | | | | | | | | | | | Currently the APTX (HD) codecs set frame_size if unset and check whether it is divisible by block_size (corresponding to block_align as used by other codecs). But this is based upon a misunderstanding of the API: frame_size is not in bytes, but in samples. Said value is also not intended to be set by the user at all, but set by encoders and (possibly) decoders if the number of channels in a frame is constant. The latter condition is not fulfilled here, so only set it for encoders. Given that the encoder can handle any number of samples as long as it is divisible by four and given that it worked to set a custom frame size before, the encoders accept any multiple of four; otherwise the value is set to the value that it already had for APTX: 1024 samples (per channel).

* avcodec/aptx: Move AudioFrameQueue to aptxenc.cAndreas Rheinhardt2022-08-271-1/+0

* avcodec/internal: Move FF_SIGNBIT and ff_log2_run to mathops.hAndreas Rheinhardt2022-03-211-1/+1
| | | | | | | It is a more fitting place for them. Also move the definition of ff_log2_run to mathtables.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.hAndreas Rheinhardt2022-03-211-0/+1
| | | | | | | | | | Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault. This reduces the amount of files that have to include internal.h (which comes with quite a lot of indirect inclusions), as e.g. most encoders don't need it. It is furthemore in preparation for moving the private part of AVCodec out of the public codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

The encoder was reverse engineered from binary library and from EP0398973B1 patent (long expired). The decoder was simply deduced from the encoder.
