Vittorio Giovara	70d246d5cc	flacenc: initialize sums matrix CC: libav-stable@libav.org Bug-Id: CID 703821	10 years ago
Reimar Döffinger	254da44bf9	flacenc: calculate lower sum levels in-place. Should improve cache usage and reduces stack usage. Also reduces number of copies in case many levels have the same number of bits. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
James Almer	3cec54b7d7	x86/flacdsp: add SSE2 and AVX decorrelate functions Two to four times faster depending on instruction set, block size and channel count.	10 years ago
James Darnley	54a51d3840	lavc/flacenc: partially unroll loop in flac_enc_lpc_16 It now does 12 samples per iteration, up from 4. From 1.8 to 3.2 times faster again. 3.6 to 5.7 times faster overall. Runtime is reduced by a further 2 to 18%. Overall runtime reduced by 4 to 50%. Same conditions as before apply. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
James Darnley	0081a14e7d	lavc/flacenc: add sse4 version of the 16-bit lpc encoder From 1.8 to 2.4 times faster. Runtime is reduced by 2 to 39%. The speed-up generally increases with compression_level. This lpc encoder is not used with levels < 3 so it provides no speed-up in these cases.

James Zern	bcaf64b605	normalize calls to ff_alloc_packet2 - check ret < 0 - remove excessive error log Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Paul B Mahol	92d874cb78	flacenc: include correct header Encoder needs put_bits.h, not get_bits.h Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Nicolas George	9e28e0035a	lavc/flacenc: improve error return. Use meaningful error codes and add log messages.	12 years ago
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.	12 years ago
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.	12 years ago
Justin Ruggles	5ff998a233	flacenc: use uint64_t for bit counts Needed to avoid integer overflows for 24-bit encoding.	12 years ago
Justin Ruggles	e783316322	flacenc: remove wasted trailing 0 bits	12 years ago
Justin Ruggles	2e76f34387	flacenc: use RICE2 entropy coding mode for 24-bit	12 years ago
Justin Ruggles	13e1ee6c84	flacenc: add 24-bit encoding	12 years ago
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.	12 years ago
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.	12 years ago
