* twinvq: Split VQF-specific part from common TwinVQ decoder coreKostya Shishkov2013-08-05

* twinvq: Prefix enums and defines shared with VoxWare MetaSoundDiego Biurrun2013-08-05

* twinvq: move all bitstream reading into single placeKostya Shishkov2013-08-05
| | | | | | | | This is required for the future addition of VoxWare MetaSound decoder, for its functions are mostly the same but bitstream reader is completely different and bitstream format is slightly different too. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* mpegts: Remove one 64-bit integer modulus operation per packetBen Avison2013-08-05
| | | | | | | | | | | | | The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms.

| | | | As for intra-refresh it is just a commodity.
* vdpau: deprecate bitstream buffers within the hardware contextRémi Denis-Courmont2013-08-05
| | | | | | | | The bitstream buffers are now private and freed by libavcodec. For backward compatibility, the hold bitstream buffer pointer is left NULL (applications were supposed to av_freep() it). Signed-off-by: Anton Khirnov <anton@khirnov.net>

* mpeg12: Ignore slice threading if hwaccel is activeRémi Denis-Courmont2013-07-25
| | | | | | | Slice threading does not work with hardware acceleration, as decoding is per-picture. This fixes Bugzilla #542. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* vdpau: Fix VC-1 interlaced modeRainer Hochecker2013-07-25

* arm: Comment out unused labels in simple_idct_armMartin Storsjö2013-07-24
| | | | | | | | | | | | | | | | | When building for iOS in thumb mode, gas-preprocessor.pl doesn't mark unused labels as thumb functions (as it does for other local labels, where it can figure out that they are functions due to being referenced in branch instructions). This leads to linker warnings for some of those local labels, such as: ld: warning: ARM function not 4-byte aligned: __a_evaluation from libavcodec/libavcodec.a(simple_idct_arm.o) Therefore, comment them out since they don't have any function. They do still have a value in documenting key points in the assembly source though. Signed-off-by: Martin Storsjö <martin@martin.st>
