2013-08-30Reinstate proper FFmpeg license for all files.Thilo Borgmann
2013-01-23Drop DCTELEM typedefDiego Biurrun
It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2012-06-08ARM: Move asm.S from libavcodec to libavutilJustin Ruggles
This will allow for easier implementation of ARM-optimized functions in libraries other than libavcodec.
2012-01-16rv34: add NEON rv34_idct_addJanne Grunau
Overall almost 4% faster, idct_add down from 350 to 85 cycles, idct_dc_add down from 83 to 30 cycles. squash: rv34 idct rearrange partial register loads
2012-01-16rv34: 1-pass inter MB reconstructionChristophe GISQUET
Implement 1-pass inverse transform and reconstruction for inter blocks.

2012-01-12rv34: NEON optimised dc only inverse transformJanne Grunau
30-50% faster than the C implementation, 0.5% overall speedup on bourne.rmvb.
2012-01-04rv34: joint coefficient decoding and dequantizationChristophe GISQUET
Perform dequantization while decoding coefficients instead of performing it on the entire coefficients buffer. Since quantized coefficients are very sparse, this usually causes a small speedup. Speedup of around 1% on Panda board compared to the removed here neon code. Global speedup is probably around 3%. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
