Andreas Rheinhardt	e625ae6092	avcodec: Constify all the AVCodecParsers Possible now that the next pointer no longer exists. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>	4 years ago
Thierry Foucu	3dc24b3379	libavcodec/mlp_parser.c: fix a use_of_uninitialized_value in target_dec_fuzzer. the target_dec_fuzzer is checking for the avpkt.data pointer but if the mlp parser cannot combine the frame, the poutbuf is not set.

James Almer	55ebf707d0	avcodec/mlp_parser: don't try to combine frames when full frames are provided Attempting full frame reconstruction is unnecessary for non raw containers, so just skip it altogether. Signed-off-by: James Almer <jamrial@gmail.com>	7 years ago
Vittorio Giovara	970c76f322	mlp_parser: Drop in-parser downmix functionality request_channel_layout is a decoder option and it makes no sense to have it in a parser. This feature was needed in the past when the decoder was allowed to reuse the avctx from the demuxer. Nowadays the decoder receives only the parameters from it, already containing the real channel layout (and the correct request_channel_layout option). After initialization the decoder overwrites the channel layout with the downmixed one that is actually output, so there is no need to preserve this functionality in the parser.

Michael Niedermayer	2d15554850	avcodec/mlp_parser: check ff_combine_frame() return code Fixes CID602338 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Tim Walker	c1e7de8f62	mlp_parser: fix request_channel_layout behavior. When request_channel_layout is 0, all substreams should be decoded. Thanks to Michael Niedermayer for spotting. Also fix a mismatch between the parser and decoder when request_channel_layout is a subset of Stereo.	11 years ago
Michael Niedermayer	bd35d58463	avcodec/mlp_parser: fix multichannel Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Tim Walker	c0c45188e5	mlp: improve request_channel_layout behavior. Don't decode further substreams if request_channel_layout is a subset of the current substream's channel_layout. Before, we would only discard further substreams if request_channel_layout matched the substream's channel_layout extactly, thus decoding additional channels which the caller would probably end up downmixing.	11 years ago
Tim Walker	4b7f1a7ced	mlp: Parse TrueHD decoder channel modifiers and set the AVMatrixEncoding for each substream.	11 years ago

Tim Walker	ed1b01131e	mlp: implement support for AVCodecContext.request_channel_layout. Also wrap usage of AVCodecContext.request_channels in FF_API_REQUEST_CHANNELS directives. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Tim Walker	b0c7e3ffd0	mlp_parser: account for AVCodecContext.request_channels when setting the channel layout. Allows users to configure the output based on what's actually decoded, rather than the full native layout. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Tim Walker	99ccd2ba10	mlp: store the channel layout for each substream. Also stop storing the channel arrangement in the header info, as it's unused outside of ff_mlp_read_major_sync. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com> CC:libav-stable@libav.org	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago

Hendrik Leppkes	b7bf93b923	mlp: Use correct speaker locations in TrueHD channel layout. (cherry picked from commit d7787835ad737d4f4d8b6f17e04d981632eeaa91) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Carl Eugen Hoyos	2a0bd2bfc9	Make a plausibility check when setting channel layout for TrueHD. TrueHD supports more channels than FFmpeg, so a valid sample could set the channel layout to a value that represents less channels than the sample actually consists of.	14 years ago
