2013-07-25mpeg12: Ignore slice threading if hwaccel is activeRémi Denis-Courmont
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>
2013-07-25vdpau: Fix VC-1 interlaced modeRainer Hochecker
VDPAU expects the bitstream value (0, 2 or 3). libavcodec uses an enum (0, 1 or 2). Signed-off-by: Rémi Denis-Courmont <remi@remlab.net> Signed-off-by: Diego Biurrun <diego@biurrun.de>

2013-07-24arm: Comment out unused labels in simple_idct_armMartin Storsjö
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>

2013-07-22fmtconvert: Add a new method, int32_to_float_fmul_array8Ben Avison
This is similar to int32_to_float_fmul_scalar, but loads a new scalar multiplier every 8 input samples. This enables the use of much larger input arrays, which is important for pipelining on some CPUs (such as ARMv6). Signed-off-by: Martin Storsjö <martin@martin.st>

2013-07-21libx264: Define X264_API_IMPORTS on MSVC/ICLDerek Buitenhuis
libx264 has a few data exports which require X264_API_IMPORTS to be defined if we link to libx264 dynamically on Windows. In a similar fashion to how we handle our compat snprintf implementation, if we define it all the time, the compiler will first try and link to __imp_x264_symbol_name, and failing that, as in the case of a static libx264, will attempt to link to the non-prefixed symbol, which has already been pulled in by other x264 functions' object files.

2013-07-15ac3dec: Don't consume more data than the actual input packet sizeMartin Storsjö
This was handled properly in the normal return case at the end of the function, but not in this special case. Returning a value larger than the input packet size can cause problems for certain library users. Returning the actual input buffer size unconditionally, since it is not guaranteed that frame_size is set to a sensible value at this point.
