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

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>
