[FFmpeg-devel] [RFC] Alpha support

[Cédric Schieli]

Hello,

Attached are two versions of the patch :
> sws_use_alpha_bloated.patch ensures that no extra code is reached for the
> non alpha case, at the cost of more bloated code (swscale.o is 9kB bigger in
> my build)
> sws_use_alpha_slower.patch only eliminates extra code when the destination
> format is not alpha capable, and uses a runtime test for the remaining cases
>

Attached version of sws_use_alpha.patch combines those two cases. The
"bloated" case is the default, the "slower" one is selected with
--enable-small

The cloberring of %ebp in yuv2packed2 has also been addressed.


Regards,
C?dric Schieli
