* x86/dsputil: put inline asm under HAVE_INLINE_ASM.Ronald S. Bultje2012-07-25
| | | | | | | This allows compiling with compilers that don't support gcc-style inline assembly. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* dsputil_mmx: fix incorrect assembly codeYang Wang2012-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | In ff_put_pixels_clamped_mmx(), there are two assembly code blocks. In the first block (in the unrolled loop), the instructions "movq 8%3, %%mm1 \n\t", and so forth, have problems. From above instruction, it is clear what the programmer wants: a load from p + 8. But this assembly code doesn’t guarantee that. It only works if the compiler puts p in a register to produce an instruction like this: "movq 8(%edi), %mm1". During compiler optimization, it is possible that the compiler will be able to constant propagate into p. Suppose p = &x[10000]. Then operand 3 can become 10000(%edi), where %edi holds &x. And the instruction becomes "movq 810000(%edx)". That is, it will stride by 810000 instead of 8. This will cause a segmentation fault. This error was fixed in the second block of the assembly code, but not in the unrolled loop. How to reproduce: This error is exposed when we build using Intel C++ Compiler, with IPO+PGO optimization enabled. Crashed when decoding an MJPEG video.

* aac: Mention abbreviation as well in long_nameDiego Biurrun2012-07-24
| | | | Most people know the codec as "AAC" and not "Advanced Audio Coding".
* v410dec: Implement explode mode supportDerek Buitenhuis2012-07-23
| | | | | | | Try and decode broken files, but still fail if explode mode is enabled. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* zerocodec: fix direct rendering.Reimar Döffinger2012-07-23
| | | | | | | | | | | | Set picture type before calling get_buffer. This allows the DR application to make better decisions. It also fixes a resource leak in case of missing reference frames since it would call get_buffer but never release_buffer. Also use FFSWAP to ensure that the AVFrame is properly initialized in the next get_buffer (in particular that data[0] is NULL).

* h264: refactor NAL decode loopRonald S. Bultje2012-07-23
| | | | | | | | | | Write out the NAL decoding loops in full so that they are easier to parse for a preprocessor without it having to be aware of macros or other such things in C code. This also makes the code more readable. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
