Hendrik Leppkes	dc2d0e06af	mlpdec: support TrueHD streams with an Atmos substream The fourth substream is being discarded, since its not raw audio data, but an encoded Atmos stream which needs a specialized decoder.

Ben Avison	b9eb03416d	truehd: break out part of output_data into platform-specific callback. Verified with profiling that this doesn't have a measurable effect upon overall performance. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Ben Avison	fcf5fc4445	truehd: tune VLC decoding for ARM. Profiling on a Raspberry Pi revealed the best performance to correspond with VLC_BITS = 5. Results for overall audio decode and the get_vlc2 function in particular are as follows: Before After Mean StdDev Mean StdDev Confidence Change 6:2 total 348.8 20.1 339.6 15.1 88.8% +2.7% (insignificant) 6:2 function 38.1 8.1 26.4 4.1 100.0% +44.5% 8:2 total 339.1 15.4 324.5 15.5 99.4% +4.5% 8:2 function 33.8 7.0 27.3 5.6 99.7% +23.6% 6:6 total 604.6 20.8 572.8 20.6 100.0% +5.6% 6:6 function 95.8 8.4 68.9 8.2 100.0% +39.1% 8:8 total 766.4 17.6 741.5 21.2 100.0% +3.4% 8:8 function 106.0 11.4 86.1 9.9 100.0% +23.1% Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Ben Avison	4e5aa080bb	truehd: break out part of rematrix_channels into platform-specific callback. Verified with profiling that this doesn't have a measurable effect upon overall performance. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Michael Niedermayer	f90a4bfc43	mlpdec: fix request_channel_layout behavior. When request_channel_layout is 0, all substreams should be decoded. Signed-off-by: Tim Walker <tdskywalker@gmail.com>	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	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

Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Nick Brereton	857c30ecba	mlpdec: Comment channel_params field in struct SubStream. Patch by Nick Brereton <nick at nbrereton dot net> Originally committed as revision 23085 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Nick Brereton	22fb814c2f	mlpdec: Allocate channel decoding parameters for each substream. Some file was encountered with a channel range that overlapped the previous substreams, and the code assumed no such overlap was possible. Patch by Nick Brereton <nick at nbrereton dot net> Originally committed as revision 23084 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	d780511b94	Reduce log level of "Extracting .. channel downmix" to AV_LOG_DEBUG, the message is pointless to ordinary users and is printed once per frame. Originally committed as revision 21486 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	0b882b4009	Fix crash in MLP decoder due to integer overflow. Probably only DoS, init_get_bits sets buffer to NULL, thus causing a NULL-dereference directly after. Originally committed as revision 21426 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	547fc46ca7	Remove pointless CONFIG_MLP_DECODER preprocessor check. The file is only ever compiled if the MLP decoder is enabled. Originally committed as revision 20968 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
