* 4xm: fix calculation of the next output line position in decode_i2_frame().Aneesh Dogra2012-01-04
| | | | | | The current code doesn't work unless width is an exact multiple of 16. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* ulti: convert to new bytestream API.Ronald S. Bultje2012-01-04

* Place some START_TIMER invocations in separate blocks.Diego Biurrun2012-01-04
| | | | | | This fixes compilation failures related to START_TIMER/STOP_TIMER macros and -Werror=declaration-after-statement. START_TIMER declares variables and thus may not be placed after statements outside of a new block.
* 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%.

* h264: return index in buffer on end-of-sequence.Ronald S. Bultje2012-01-03
| | | | | Fixes hangs if the last packet contains an end-of-sequence NAL unit, bug 158.
* Merge some declarations and initializations.Diego Biurrun2012-01-04
| | | | | | This fixes compilation failures related to START_TIMER/STOP_TIMER macros and -Werror=declaration-after-statement. START_TIMER declares variables and thus may not be placed after statements outside of a new block.

* alacdec: implement the 2-pass prediction type.Justin Ruggles2012-01-03
| | | | | The reference encoder does not generate any streams using this, but the reference decoder can handle it, so we should as well.
* alacenc: implement the 2-pass prediction type.Justin Ruggles2012-01-03
| | | | This isn't used by the reference encoder, but it is supported by the decoder.

* alacdec: fill in missing or guessed info about the extradata format.Justin Ruggles2012-01-03
| | | | | Now that there is official documentation from Apple about this, we don't have to guess anymore.

* threads: limit the number of automatic threads to MAX_AUTO_THREADSJanne Grunau2012-01-01
