Paul B Mahol	3e7d684912	avcodec/flacenc: fix calculation of bits required in case of custom sample rate Sample rate of 11025 takes 16 bits but previous code would pick only 8. Fixes assertion failure. Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com> Signed-off-by: Paul B Mahol <onemda@gmail.com>	9 years ago
Vittorio Giovara	243df1351d	lavc: Move {min,max}_prediction_order to codec private options These options are only used by alac and flac. They are very codec-specific options, so deprecate the global variants. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Paul B Mahol	367ffa0c15	avcodec/flacenc: use designated initializers for AVClass Signed-off-by: Paul B Mahol <onemda@gmail.com>	9 years ago
Clément Bœsch	fb99ef0bd3	avcodec: use AV_OPT_TYPE_BOOL in a bunch of places	9 years ago
Vittorio Giovara	79d89cf2f4	flacenc: Clamp user-supplied min/max prediction orders This mimics what the code does internally for default order values. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Ronald S. Bultje	93866c2aa2	intmath: remove av_ctz. It's a non-installed header and only used in one place (flacenc). Since ff_ctz is static inline, it's fine to use that instead.	9 years ago
Vittorio Giovara	6064f697a3	lavc: Enable side data only packets by default Deprecate the now unused option, but temporarily retain the capability to disable the now default behaviour. Mention this change in the AVPacket documentation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Vittorio Giovara	def97856de	lavc: AV-prefix all codec capabilities Express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
George Boyle	2469ed32c8	avcodec/flacenc: Fix Invalid Rice order Fixes ticket #4628. The problem arose, in the sample file at least, in the last block where the minimum and maximum Rice partition orders were both 0. In that case, and any other where pmax == pmin, the original UINT32_MAX placeholder value for bits[opt_porder] was getting overwritten before the comparison to check if the current partition order is a new optimal, so the correct partition order and RiceContext params were not being set.

Michael Niedermayer	fccde16afa	avcodec/flacenc: Simplify sizeof() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	215410860f	avcodec/flacenc: Mark pointers/array arguments const which are not changed Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	5dfcb4f74d	avcodec/flacenc: Simplify md5 calculation code by using AV_WL24() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	7786a91b47	avcodec/flacenc: Move udata and sums to FlacSubframe This significantly reduces the amount of stack space needed and also permits to simply copy the rice context again without speed penalty Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	80f9d6e0ab	avcodec/flacenc: Support calculating rice parameters exactly Some files benefit by about 0.3% from this, and speedwise its ok other files do not benefit and encode to the same size Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	d3dcd28812	avcodec/flacenc: Do not copy unused udata array -> 5x faster calc_rice_params() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Carl Eugen Hoyos	e609cfd697	lavc/flac: Fix encoding and decoding with high lpc. Based on an analysis by trac user lvqcl. Fixes ticket #4421, reported by Chase Walker.	10 years ago
Vittorio Giovara	f5ba67ee13	flacenc: Move a scratch buffer to struct used by the function This avoids allocating/freeing memory at every function call, checking its return value, and carrying the error around.	10 years ago
Michael Niedermayer	09b0f227ce	avcodec/flacenc: also count wasted bits in subframe_count_exact() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
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.

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
