Diego Biurrun 804d7a1aa6 doxygen: Fix function parameter names to match the code 2012-08-09 20:05:55 +02:00
Mans Rullgard c318626ce2 x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h 
This puts x86-specific things in the x86/ subdirectory where they
belong.

Diego Biurrun 239fdf1b4a x86: build: replace mmx2 by mmxext 
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.

Diego Biurrun d1505db067 x86: yadif: Mark mmxext optimizations as such 
The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext
instructions, causing sigills on CPUs that do not support mmxext.

Justin Ruggles be51e589cd af_asyncts: avoid overflow in out_size with large delta values 2012-07-29 14:31:54 -04:00
Justin Ruggles 70d71b5801 af_asyncts: add first_pts option 
This allows for padding/trimming at the start of stream. By default, no
assumption is made about the first frame's expected pts, so no padding or
trimming is done.

Justin Ruggles 743f07062a lavfi: better channel layout negotiation 
Allow substitution of channel pairs in the input for nearby channel pairs in
the output in order to get a closer match. Also weigh LFE channel mismatch
differently to favor matching the same layout without LFE over one less
channel with LFE.

Directly forwarding the input buffer to the next filter means that
drawtext no longer owns any references to it and thus shouldn't refer to
it in any way.
