* avcodec/opus: always use ambisonic layout for mapping family 2James Almer2022-03-20
| | | | | | | | | | | No need to use a Custom layout when the non diegetic channels can be described as a standard mask. This fixes: 45684/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_LIBOPUS_fuzzer-5039410989629440 Signed-off-by: James Almer <jamrial@gmail.com>

* libopus: decode ambisonics with non-diegetic sourcesFelicia2017-02-17
| | | | | | | | | | | Channel mapping 2 additionally supports a non-diegetic stereo track appended to the end of a full-order ambisonics signal, such that the total channel count is either (n + 1) ^ 2, or (n + 1) ^ 2 + 2 where n is the ambisonics order Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* libavcodec/opus: Add channel mapping 2 to extradata parserMichael Graczyk2016-09-01
| | | | | | | | This allows libavcodec/opus to demux ambisonics in an ogg/opus container. Channel mapping family 2 is being added in this standards track IETF draft: tools.ietf.org/html/draft-ietf-codec-ambisonics-00 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* | all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.hGanesh Ajjanagadde2016-03-22
| | | | | | | | | | | | | | | | | | | | | | The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things. Note that this is not exported; use lavu/mathematics for such purposes. Reviewed-by: Ronald S.
