* flacdec: allocate sample buffers with av_mallocMans Rullgard2012-07-04
| | | | | | | | | The buffers are only allocated once, although it can happen from any of a few different places, so there is no need to use realloc. Using av_malloc() ensures they are aligned suitably for SIMD optimisations. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | This value does not need to be persistent across calls.

* wma: Lower the maximum number of channels to 2Martin Storsjö2012-07-01
| | | | | | | | | | | ff_wma_init is used only by wmadec and wmaenc, and neither of them can handle more than 2 channels. This fixes crashes with invalid files. Based on patch by Piotr Bandurski and Michael Niedermayer. Signed-off-by: Martin Storsjö <martin@martin.st>
* ARM: generate position independent code to access data symbolsMans Rullgard2012-07-01
| | | | | | | | | | | This creates proper position independent code when accessing data symbols if CONFIG_PIC is set. References to external symbols should now use the movrelx macro. Some additional code changes are required since this macro may need a register to hold the GOT pointer. Signed-off-by: Mans Rullgard <mans@mansr.com>

* x86: fmtconvert: add special asm for float_to_int16_interleave_misc_*Ronald S. Bultje2012-06-30
| | | | | | This gets rid of a variable-length array and a for loop in C code. Signed-off-by: Martin Storsjö <martin@martin.st>
* x86: vc1: fix and enable optimised loop filterMans Rullgard2012-06-30
| | | | | | | | | | | | | | | | | | | | | | The problem is that the ssse3 psign instruction does the wrong thing here. Commit ea60dfe incorrectly removed a macro emulating this instruction for pre-ssse3 code. However, the emulation is incorrect, and the code relies on the behaviour of the macro. Specifically, the psign sets destination elements to zero where the corresponding source element is zero, whereas the emulation only negates destination elements where the source is negative. Furthermore, the PSIGNW_MMX macro in x86util.asm is totally bogus, which is why the original VC-1 code had an additional right shift when using it. Since the psign instruction cannot be used here, skip all the macro hell and use the working instruction sequence directly. None of this was noticed due a stray return statement in ff_vc1dsp_init_mmx() which meant that only the mmx version of the loop filter was ever used (before being removed in ea60dfe).

* x86: fft: replace call to memcpy by a loopChristophe Gisquet2012-06-27
| | | | | | | | | The function call was a mess to handle, and memcpy cannot make the assumptions we do in the new code. Tested on an IMC sample: 430c -> 370c. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dxva2: include dxva.h if foundRonald S. Bultje2012-06-27
| | | | | | | | Apparently, some build environments require dxva.h even for dxva2, while others lack this header entirely. Including it conditionally allows building in both cases. Signed-off-by: Martin Storsjö <martin@martin.st>
* dxva2_h264: fix signaling of mbaff framesHendrik Leppkes2012-06-26
| | | | | | | The MBAFF flag may only be signaled if we're actually dealing with a full frame, and not singular fields, as it can happen in mixed content. Signed-off-by: Martin Storsjö <martin@martin.st>
