* 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>

* lavc: remove stats_in from AVCodecContext options table.Anton Khirnov2012-06-21
| | | | | | | | | | | | Its documentation states that it is allocated/freed by the caller, but it is declared as an AV_OPT_TYPE_STRING AVOption. Since 367732832faaf1bac4ece37cf7fef8c911e16312 the AVOptions system frees strings automatically. This can be considered an API break, since it won't work when the caller doesn't use av_malloc() to allocate the memory or wants to use the string after closing the codec. Since there is not much value in this field being an AVOption, the best solution is to remove it from the options table.

* iac: generate codec tables as they are supposed to beKostya Shishkov2012-06-09
| | | | | | | | | Unlike its predecessor, Indeo Audio codec generates tables depending on sampling rate. Previously decoder used pre-generated tables for 22050 Hz which obviously doesn't work with other frequencies. Many thanks to Maxim Poliakovsky for providing all needed information for this.
