* h264: use templates to avoid excessive inliningMans Rullgard2012-07-05
| | | | | | | | | | | | | Instead of inlining everything into ff_h264_hl_decode_mb(), use explicit templating to create versions of the called functions with constant parameters filled in. This greatly speeds up compilation of h264.c and reduces the code size without any measurable impact on performance. Compilation time for h264.c on an i7 goes from 30s to 5.5s. Code size is reduced by 430kB. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegvideo: Don't use ff_mspel_motion() for vc1Michael Niedermayer2012-07-05
| | | | | | | | | | Using ff_mspel_motion assumes that s (a MpegEncContext poiinter) really is a Wmv2Context. This fixes crashes in error resilience on vc1/wmv3 videos. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* amr: remove shift out of the AMR_BIT() macro.Ronald S. Bultje2012-07-04
| | | | | | MSVC doesn't like the offsetof(..) >> 1 construct, it interprets it as a non-literal, thus causing use of this in static tables to fail compilation.

* 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>

* 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: 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>
