2013-03-27dca: Move ff_dca_convert_bitstream() to the DCA common codeDiego Biurrun
This makes the DCA parser and decoder independent.
2012-08-01dca: Switch dca_sample_rates to avpriv_ prefix; it is used across libsDiego Biurrun
2012-08-01dca: Move tables used outside of dcadec.c to a separate file.Diego Biurrun
2012-08-01dca: Rename dca.c ---> dcadec.cDiego Biurrun
This will allow adding dca.c with tables used from other files.
2012-06-19float_dsp: Move vector_fmac_scalar() from libavcodec to libavutilJustin Ruggles
2012-03-08dca: include libavutil/mathematics.h for possibly missing M_SQRT1_2Kostya Shishkov
2012-03-07dca: don't use av_clip_uintp2().Ronald S. Bultje
The argument is not a literal, thus causing the ARM v6 or later builds to break.
2012-03-07dca: prevent accessing static arrays with invalid indexes.Ronald S. Bultje

2011-12-03Add avcodec_decode_audio4().Justin Ruggles
Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
2011-11-28dca: Replace oversized unused get_bits() with skip_bits_long().Alex Converse
2011-11-25Make channel layout masks unsignedMans Rullgard
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>
2011-11-25dca: ARMv6 optimised decode_blockcode()Mans Rullgard
This is a hand-tuned version of the code with impossible parts of the FASTDIV function ommitted. 2-5% faster overall on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-10-30dca: handle errors from dca_decode_block()Justin Ruggles
Return error if core block decoding fails. Do not enable XCh if XCh extension block decoding fails.
2011-10-30dca: return error if the frame header is invalidJustin Ruggles
2011-10-30dca: return proper error codes instead of -1Justin Ruggles

2011-09-29dca: clear inactive subbands only once in qmf_32_subbands()Mans Rullgard
Writing zeros to the high entries in the array need only be done once as the cutoff position is constant throughout the loop. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-09-28dca: use vector_fmac_scalar from dsputilMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-07-04dca: set AVCodecContext frame_size for DTS audioJohn Stebbins
Set the frame size when decoding DTS audio. This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly inaccurate frame duration estimate.

2011-07-01cosmetics: fix some then/than typosDiego Biurrun
2011-06-21Replace usages of av_get_bits_per_sample_fmt() with av_get_bytes_per_sample().Justin Ruggles
av_get_bits_per_sample_fmt() is deprecated.
2011-06-02Remove unused variablesMans Rullgard
2011-05-19Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbisJustin Ruggles
decoders. Based on patches by clsid2 in ffdshow-tryout.

2011-02-25dca: use EXT_AUDIO_ID field to determine core extensionsAnssi Hannula
This avoids the core substream extensions scan when the EXT_AUDIO_ID field indicates no extensions or only unsupported extensions. The scan is done only if the value of EXT_AUDIO_ID is unknown or indicates a present XCh extension which we can decode. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-15Merge libavcore into libavutilReinhard Tartler
It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

2011-02-02Separate format conversion DSP functions from DSPContext.Justin Ruggles
This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>

2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò

2011-01-22dca: consider a stream with XXCh/X96 in ExSS as DTS-HD HRAAnssi Hannula
DTS-HD HRA streams do not always have an XBR extension in the extension substream. Instead they can have only XXCh and X96 extensions in there and still be considered DTS-HD HRA. This is also confirmed with Onkyo TX-SR607 receiver which recognizes such a stream as HiRes Audio. Signed-off-by: Mans Rullgard <mans@mansr.com>

2010-10-03Add the CODEC_CAP_CHANNEL_CONF capability code and addBenjamin Larsson
that flag to the dca codec. This capability when set will make sure the codec will initialize the channel configuration instead of trusting the container. This fixes issue 2137 and issue 850. Originally committed as revision 25320 to svn://svn.ffmpeg.org/ffmpeg/trunk
