Anton Khirnov f073b1500e lavc: remove disabled FF_API_OLD_ENCODE_AUDIO cruft 2013-03-09 08:36:40 +01:00
Janne Grunau 480be07a96 flac: change minimum and default of lpc_passes option to 1
Avoid use of uninitialized and uncomputed linear least square models
during ff_lpc_calc_coefs() for FF_LPC_TYPE_CHOLESKY. Fixes running
make fate-flac-16-lpc-cholesk with valgrind --undef-value-errors=yes.

Justin Ruggles 3a2731cbd3 flacenc: ensure the order is within the min/max range in LPC order search
This fixes use of uninitialized values when the FLAC encoder uses the
2-level, 4-level, and 8-level search methods. Fixes failure of the
fate-flac-24-comp-8 test when run using valgrind.

Justin Ruggles 2e76f34387 flacenc: use RICE2 entropy coding mode for 24-bit 2012-11-05 15:32:30 -05:00
Justin Ruggles 13e1ee6c84 flacenc: add 24-bit encoding 2012-11-05 15:32:30 -05:00
Justin Ruggles 799e232490 flacdsp: move lpc encoding from FLAC encoder to FLACDSPContext
Also, templatize the functions for 16-bit and 32-bit sample range. This will
be used for 24-bit FLAC encoding.

Justin Ruggles 5ff998a233 flacenc: use uint64_t for bit counts
Needed to avoid integer overflows for 24-bit encoding.

Justin Ruggles 6a744d2619 flacenc: use a separate buffer for byte-swapping for MD5 checksum on big-endian
This is much faster than calculating the MD5 one sample at a time.
