| * ARMv6: vp8: fix stack allocation with Apple's assemblerMans Rullgard2012-08-041-1/+7
| | | | | | | | | | | | | | | | In the GNU assembler, a relational expression, bizarrely, has the value -1 if true, whereas in Apple's it is +1. This patch makes sure the correct expression is used in both cases. Signed-off-by: Mans Rullgard <mans@mansr.com>
| * ARM: vp56: allow inline asm to build with clangMans Rullgard2012-08-041-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The clang integrated assembler does not support pre-UAL syntax, while gcc requires pre-UAL syntax for ARM code. A patch[1] for clang to support the old syntax as well has been ignored since January. This patch chooses the syntax appropriate for each compiler, allowing both to build the code. Notably, this change allows building for iphone with the latest Apple Xcode update. [1] http://llvm.org/bugs/show_bug.cgi?id=11855 Signed-off-by: Mans Rullgard <mans@mansr.com>

| * x86: build: replace mmx2 by mmxextDiego Biurrun2012-08-0319-33/+32
| | | | | | | | | | | | | | Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.
| * Revert "wmapro: prevent division by zero when sample rate is unspecified"Ronald S. Bultje2012-08-031-5/+0
| | | | | | | | | | This reverts commit 36936080239ba9e162f9f5d0f722ce579cb606cf. It was already applied; no idea why it didn't error out while re-applying it.

| * lagarith: pad RGB buffer by 1 byte.Ronald S. Bultje2012-08-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | For left HFYU prediction, we predict from the buffer buf+1 using 8- or 16-byte reads. This means that aligning the buffer by 16 bytes is in itself not sufficient, because if the width itself is 16- or 8-byte aligned, the buffer will not be padded, and thus a read of size 16 at buf+1 will overflow boundaries at the right edge. Padding the buffer by 1 byte is sufficient to not overflow its boundaries. Fixes bug 342.
| * dsputil: make add_hfyu_left_prediction_sse4() support unaligned src.Ronald S. Bultje2012-08-031-7/+13
| | | | | | | | | | | | | | | | | | | | This makes add_hfyu_left_prediction_sse4() handle sources that are not 16-byte aligned in its own function rather than by proxying the call to add_hfyu_left_prediction_ssse3(). This fixes a crash on Win64, since the sse4 version clobberes xmm6, but the ssse3 version (which uses MMX regs) does not restore it, thus leading to XMM clobbering and RSP being off. Fixes bug 342.

* | | movtextenc: 3GPP TS 26.245 Timed Text Encoder.Philip Langdale2012-08-044-2/+165
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces a basic encoder for 3GPP Timed Text subtitles, also known as TX3G, Quicktime subtitles, or "movtext" in the existing code. This initial change doesn't attempt to write styling information, and just writes the plain text of the subtitles. I intend to add support for styles eventually, but it's challenging due to a lack of existing players that support them. Note that an additional change is required to the mov/mp4 muxer to write empty subtitle packets to indicate subtitle duration. Signed-off-by: Philip Langdale <philipl@overt.org>

| * vc1dec: Remove separate scaling function for interlaced field MVsMashiat Sarker Shakkhar2012-08-031-22/+8
| | | | | | | | | | | | | | The scaling process for obtaining direct MVs from co-located field MVs is the same for interlaced field and progressive pictures. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
| * vc1dec: Invoke edge_emulation regardless of MV precisionMashiat Sarker Shakkhar2012-08-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | In VC-1 interlaced field pictures, chroma motion vectors can extend beyond picture boundary even if luma vectors are bounded. The problem shows up only for hpel interpolated MVs, and may be due to the way motion vectors are scaled / cropped. Thanks to Konstantin Shishkov for suggesting the fix. This fixes long-known segfaults in MC-VC1.ts from videolan streams archive. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
| * x86: Use consistent 3dnowext function and macro name suffixesDiego Biurrun2012-08-036-43/+45
| | | | | | | | | | | | Currently there is a wild mix of 3dn2/3dnow2/3dnowext. Switching to "3dnowext", which is a more common name of the CPU flag, as reported e.g. by the Linux kernel, unifies this.

| | | | | | | | | | | | Fixed codebook mode in 5300 rate may write up to SUBFRAME_LEN + 4 and that is considered normal by the reference decoder. Without that additional padding it might overwrite first elements of LPC history.
