nu774	6ec688e1bc	mp3: enable packed main_data decoding in MP4 14496-3 suggests packing main_data of MP3 that is usually scattered into multiple frames due to bit reservoir. However, after packing main_data into a access unit, bitrate index in the MPEG audio frame header doesn't match with actual frame size. In order to accept this, this patch removes unnecessary frame size checking on mp3 decoder. Also, mov demuxer was changed to use MP3 parser only on special cases (QT MOV with specific sample description) to avoid re-packetizing. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago

Martin Storsjö	35686a289f	mp3adu: Set the channel layout properly This fixes decoding, broken since `7e35037`. This is similar to what was done for the normal mp3 decoder in `f4a86bc9`. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Kostya Shishkov	b37d945dd4	mp3: fix start band index for block type 2 in 8kHz audio In hybrid frames long window part ends at 36 samples for most of the cases but at 72 for 8kHz case. For some reason decoder assumed it's 48 or even 36 samples, which caused wrong bitstream decoding for such blocks. l3_25207.mpg from conformance suite demonstrates it the best.	13 years ago
Diego Biurrun	aa3f2cb584	mpegaudiodec: Do not discard mp_decode_frame() return value. This fixes the warning: libavcodec/mpegaudiodec.c:1704:14: warning: variable ‘out_size’ set but not used	13 years ago
Kostya Shishkov	a05c41acd1	mp3dec: perform I/S and M/S only when frame mode is joint stereo. Looks like some LAME versions produce dual stereo mode MP3s with flags for intensity and middle stereo set. In this mode those flags should be ignored like the reference decoder and derived ones do.	13 years ago

Anton Khirnov	02beb9826b	lavc: deprecate AVCodecContext.sub_id. In most places where it's used, it's as a pointless write-only field. Only rv10 decoder actually reads from it, but it stores some internal version info in it. There is no reason for it to be in a public field.	13 years ago

Dale Curtis	b716542691	mpegaudiodec: Prevent premature clipping of mp3 input buffer. Instead of clipping extrasize based on EXTRABYTES, clip based on the amount of buffer actually left. Without this fix, there are warbles and other distortions in the test case below. http://kevincennis.com/mix/assets/sounds/1901_voxfx.mp3	13 years ago
Ronald S. Bultje	3e13005cac	mp3on4: require a minimum framesize. If bufsize < headersize, init_get_bits() will be called with a negative number, causing it to fail and any subsequent call to get_bits() will crash because it reads from a NULL pointer.

Justin Ruggles	03fafdec82	mpegaudiodec: skip all channels when skipping granules Also fix calculation of new position when switching buffers. This fixes "overread" error messages when seeking.	13 years ago
Ronald S. Bultje	464f26889c	mpegaudiodec: fix seeking. The safe bitstream reader does not allow using skip_bits_long() to seek to a point before the start of the buffer, which was needed by the mp3 decoder. This change instead calculates the start point of the first valid granule and skips to that position. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago

Mans Rullgard	ac08f798bb	mp3dec: hack: fix decoding with safe bitstream reader The buffer splicing relies on the bitstream reader over-reading the end of the buffer as declared in init_get_bits(), although more data is actually present. Manually moving the bitstream boundary after init_get_bits() allows this to work as expected. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 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
