DECLARE_ALIGNED macro for TMS470 compiler
...
This compiler supports gcc-style alignment attributes for struct,
but not for global variables. For the latter, alignment can be
specified with a pragma, which does not work for struct members or
local variables. By using both pragma and attribute, one or the
other will always take effect.
Unfortunately, no means exists for aligning stack variables.

Make DECLARE_ALIGNED macros work with external array specifiers
...
The macro implementation might need the name of the variable being
declared for compiler-specific syntax. Moving array specifiers outside
the macro invocation allows this to work.

H264 DXVA2 implementation
...
It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.
To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h )
The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.
