* lavu: Add a pixel format for new VDA hwaccelAnton Khirnov2014-05-11
| | | | | The current hwaccel is broken and cannot be fixed in a compatible way. It will be deprecated and replaced with a new one.

* replaygain: correctly parse peak valuesAlessandro Ghedini2014-04-04
| | | | | | | | | | | | | | | According to the ReplayGain spec, the peak amplitude may overflow and may result in peak amplitude values greater than 1.0 with psychoacoustically coded audio, such as MP3. Fully compliant decoders must allow peak overflows. Additionally, having peak values in the 0<->UINT32_MAX scale makes it more difficult for applications to actually use the peak values (e.g. when implementing clipping prevention) since values have to be rescaled down. This patch corrects the peak parsing by removing the rescaling of the decoded values between 0 and UINT32_MAX and the 1.0 upper limit. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* float_dsp: Replace arch optimization ifdefs by if cascadeDiego Biurrun2014-03-22
| | | | Arch-specific optimizations are handled this way everywhere else.
* float-dsp-test: do not use C99's predefined __func__Janne Grunau2014-03-20
| | | | | It is not supported by all compilers on FATE. Fixes "some test were skipped" errors.
* float_dsp: Use LOCAL_ALIGNED for instead of DECLARE_ALIGNED within functionsMartin Storsjö2014-03-19
| | | | | | This fixes fate-float_dsp-test on RVCT 4.0. Signed-off-by: Martin Storsjö <martin@martin.st>
* aarch64: float_dsp NEON assemblerJanne Grunau2014-03-18
| | | | | | | Ported from arm NEON and added vector_dmul_scalar. Functions between 1.5 and 5 times faster than the C implementations using Apple's clang-503.0.19 on A7.

* timer: use mach_absolute_time as high resolution clock on darwinJanne Grunau2014-03-09
| | | | | | | | | | Not guaranteed to be in nanosecond resolution. On iOS 7 the duration of one tick is 125/3 ns which is still more than an order of magnitude better then microseconds. Replace decicycles with the neutral UNITS. Decicycles is strange but tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time is just silly.

* x86: float dsp: unroll SSE versionsChristophe Gisquet2014-02-20
| | | | | | | | | | vector_fmul and vector_fmac_scalar are guaranteed that they can process in batch of 16 elements, but their SSE versions only does 8 at a time. Therefore, unroll them a bit. 299 to 261c for 256 elements in vector_fmac_scalar on Arrandale/Win64. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

* AVOptions: deprecate unused AV_OPT_FLAG_METADATAAnton Khirnov2014-02-19
| | | | | It was never used since it was added and the things it was intended for are now exported differently.
* threads: Check w32threads dependencies at the configure stageDiego Biurrun2014-02-19
| | | | | Also add warning comment about threading implementations without matching atomics implementation to the atomics fallback implementation.
* arm: Mark the stack as non-executableMartin Storsjö2014-02-19

* log: Have function parameter names match between .c and .h fileDiego Biurrun2014-02-12
| | | | This fixes two related Doxygen warnings.
* arm: Add EXTERN_ASM to the .func and .type declarations for exported symbolsMartin Storsjö2014-02-07
| | | | | | | | | | | | | | | This makes the generated assembly more internally consistent, avoiding declaring two labels for the same function (for cases where EXTERN_ASM is empty) and not declaring a separate unprefixed label in other cases. This also makes sure the .func and .type delcarations have the same prefix. They have previously not been used on the platforms that have prefixed symbols on arm (iOS), but gas-preprocessor has recently started using the .func declarations for adding .thumb_func declarations for such functions.
