| | | | | | | | | | | | | | | | | | Author: Mans Rullgard <mans@mansr.com> Date: Sun Dec 11 21:41:59 2011 +0000 x86: cabac: replace explicit memory references with "m" operands This replaces the explicit offset(reg) memory references with "m" operands for the same locations. As a result, one fewer register operand is needed for these inline asm statements. This change appears to have broken compilation on darwin, and subsequent fixes by martin (which did not fix compilation) removed the register advantage, thus this change seems not a good idea to keep.

* Check for overread in vqa video decoder.Reimar Döffinger2012-01-05
| | | | | | | | This issue was discovered while decoding the FATE sample vqa/ws_snd.vqa. For some unknown reason only audio decoding is tested by FATE for that file, but not video. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* sipr: fall back to setting mode based on bit_rate.Reimar Döffinger2012-01-05
| | | | | | | | | | | Not all applications (e.g. MPlayer) set block_align, and when using a different demuxer it might not even be easily available. So fall back to selecting mode based on bit rate as before if block_align has not useful value. It can't be worse than failing to decode completely.

| * vc1dec: fix invalid memory access for small video dimensionsJohn Brooks2012-01-04
| | | | | | | | | | | | | | | | | | | | | | For small video dimensions, these calculations of the upper bound for pixel access may have a negative result. Using an unsigned comparison to bound a potentially negative value only works if the greater operand is non-negative. Fixed by doing edge emulation when the upper bound is probably negative, everywhere that this pattern appears. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
| * rv34: fix invalid memory access for small video dimensionsJohn Brooks2012-01-04
| | | | | | | | | | | | | | | | | | For small video dimensions calculations of the upper bound for pixel access may result in negative value. Using an unsigned comparison works only if the greater operand is non-negative. This is fixed by doing edge emulation explicitly for such conditions.

| * rv34: joint coefficient decoding and dequantizationChristophe GISQUET2012-01-04
| | | | | | | | | | | | | | | | | | | | | | 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%.
