Jan Ekström	79b057f1b7	avcodec/mpeg4audio: add newer channel_coding mappings Additionally, add comments regarding their definitions. Based on ARIB STD-B32, which bases on 14496-3:2009 and 14496-3:2009/AMD4.	4 years ago

Jun Zhao	333109f469	lavc/mpeg4audio: add chan_config check to avoid indeterminate channels add chan_config check to avoid indeterminate channels. Signed-off-by: Jun Zhao <barryjzhao@tencent.com> Signed-off-by: James Almer <jamrial@gmail.com>	5 years ago
James Almer	f96a8b015f	avcodec/mpeg4audio: add avpriv_mpeg4audio_get_config2() Identical to avpriv_mpeg4audio_get_config() except taking a size argument in bytes, and featuring a new logging context paremeter. Schedule avpriv_mpeg4audio_get_config() for removal as soon as major is bumped as well. Signed-off-by: James Almer <jamrial@gmail.com>	5 years ago
Anton Khirnov	831018b0bb	mpeg4audio: Make avpriv_copy_pce_data() inline The function currently accepts a PutBitContext and a GetBitContext, which hardcodes their sizes into the lavc ABI. Since the function is quite small and only called in a few places, the simplest solution is making it inline, thus avoiding a runtime dependency completely.

Andreas Cadhalpun	0747754622	mpeg4audio: validate sample_rate A negative sample rate doesn't make sense and triggers assertions in av_rescale_rnd. Also check for errors from avpriv_mpeg4audio_get_config in ff_mp4_read_dec_config_descr. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	8 years ago

Janne Grunau	fd095539d1	latmdec: fix audio specific config parsing Pass the correct size in bits to mpeg4audio_get_config and add a flag to disable parsing of the sync extension when the size is not known. Latm with AudioMuxVersion 0 does not specify the size of the audio specific config. Data after the audio specific config can be misinterpreted as sync extension resulting in random and wrong configs.	13 years ago
