2016-05-31avcodec/dca: require checked bitstream readerfoo86
Remove half-working attempt at supporting unchecked bitstream reader by always copying input data into intermediate buffer with large amount of padding at the end. Convert LBR decoder to checked bitstream reader. Convert dcadec_decode_frame() to parse input data directly if possible. Signed-off-by: James Almer <jamrial@gmail.com>
2016-05-21avcodec/dca: simplify 'residual ok' flag trackingfoo86
Move this from separate structure field to a packet flag. Behavior should be equivalent, except that residual flag is now properly cleared when packet has no core frame at all. Also print a message when forcing recovery mode due to invalid residual to make debugging easier. Signed-off-by: James Almer <jamrial@gmail.com>
2016-05-20avcodec/dca: don't set initial sample_fmtfoo86
Valid sample_fmt will be set by dcadec_decode_frame() based on stream type. Signed-off-by: James Almer <jamrial@gmail.com>

2015-12-24dca: remove unused decode_hf function and quant_d tablesAlexandra Hájková
They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.
2015-12-23dca: change the core to work with integer coefficients.Alexandra Hájková
The DCA core decoder converts integer coefficients read from the bitstream to floats just after reading them (along with dequantization). All the other steps of the audio reconstruction are done with floats which makes the output for the DTS lossless extension (XLL) actually lossy. This patch changes the DCA core to work with integer coefficients until QMF. At this point the integer coefficients are converted to floats. The coefficients for the LFE channel (lfe_data) are not touched. This is the first step for the really lossless XLL decoding.
2015-12-12lavc: add profiles to AVCodecDescriptorAnton Khirnov
The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.
