2016-01-24avcodec/flacenc: fix calculation of bits required in case of custom sample ratePaul B Mahol
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>
2016-01-21lavc: Move {min,max}_prediction_order to codec private optionsVittorio Giovara
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>

This mimics what the code does internally for default order values. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
2015-10-12intmath: remove av_ctz.Ronald S. Bultje
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.
2015-09-12lavc: Enable side data only packets by defaultVittorio Giovara
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>

2015-07-27avcodec: Add a min size parameter to ff_alloc_packet2()Michael Niedermayer

2015-06-16avcodec/flacenc: Fix Invalid Rice orderGeorge Boyle
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.

Two to four times faster depending on instruction set, block size and channel count.
2014-08-13lavc/flacenc: partially unroll loop in flac_enc_lpc_16James Darnley
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>
2014-08-13lavc/flacenc: add sse4 version of the 16-bit lpc encoderJames Darnley
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. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
