* x86: h264_intrapred: Don't add the 'd' suffix to the SPLATB_REG macroMartin Storsjö2012-07-06
| | | | | | | | | | | | | The SPLATB_REG macro already adds the 'd' suffix internally. This fixes building on Win64, which has been broken since 878e66902. This worked for unix, where r2 happened to be rdx in this case, which with the first suffix rdxd was mapped to eax, and eaxd is defined back to eax. On win64 however, r2 happened to be R8 in this case, and R8d mapps to R8D just fine, but there's no mapping for R8Dd to anything. Signed-off-by: Martin Storsjö <martin@martin.st>

* 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>

| | | | | | 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.

| | | | | | | | | 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>

| | | | | | | | | | | 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).
