* avcodec/dca: return standard error codes in avpriv_dca_parse_core_frame_header()James Almer2017-11-01

| | | | | | | | | avpriv_dca_parse_core_frame_header() This prevents potential ABI issues with GetBitContext. Reviewed-by: foo86 <foobaz86@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec: add avpriv_dca_parse_core_frame_header()foo862017-07-18
| | | | | | | | There are 3 different places where DCA core frame header is parsed: decoder, parser and demuxer. Each one uses ad-hoc code. Add common core frame header parsing function that will be used in all places. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/dca: move bits per sample array to dca.cfoo862017-07-18
| | | | | | | It will be used by the parser. This change avoids unwanted parser dependency on dcadata. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/dca: support EXSS marker in avpriv_dca_convert_bitstream()foo862016-05-31
| | | | | | | This is now required by dcadec_decode_frame(). All remaining users of avpriv_dca_convert_bitstream() have been updated to expect EXSS marker. Signed-off-by: James Almer <jamrial@gmail.com>

* dca: fix misaligned access in avpriv_dca_convert_bitstreamAndreas Cadhalpun2016-01-14
| | | | | | | | | | | src and dst are only 8-bit-aligned, so accessing them as uint16_t causes SIGBUS crashes on architectures like sparc. This fixes ubsan runtime error: load of misaligned address for type 'const uint16_t', which requires 2 byte alignment Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>
