* avcodec/dcadec: Treat the input packet's data as constAndreas Rheinhardt2022-07-04
| | | | | | | | A decoder's input packet need not be writable, so we must not modify the data. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* 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/dca: clear X96 channels if nothing was decodedfoo862016-03-06
| | | | | | | | The first X96 channel set can have more channels than core, causing X96 decoding to be skipped. Clear the number of decoded X96 channels to zero in this rudimentary case. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
