* avcodec/dca: Unavpriv dca_sample_ratesAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | Said table is 64 bytes long and exported so that it can be used both in libavcodec and libavformat. This commit stops doing so and instead duplicates it for shared builds, because the overhead of exporting the symbol is bigger than 64 bytes. It consists of the length of the name of the symbol (2x24 bytes), two entries in .dynsym (2x24 bytes), two entries for symbol version (2x2 bytes), one hash value in the exporting library (4 bytes) in addition to one entry in the importing library's .got and .rela.dyn (8 + 24 bytes). (The above numbers are for a Linux/GNU/Elf system; the numbers for other platforms may be different.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.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>

* 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>
