Hi All,
Colorspace:
It would be nice to have a 32 bit rgb colorspace that is packed argb.
I made this in my copy of xvid and its quite simple to do this (and I
think it doesn't hurt somebody if there are 5 lines more code), but
it's QuickTime's native format on mac, so I get a good performance
gain.
The other thing is:
I would like to begin optimizing. I sampled my encoder and saw much
time is spent in 'sad'.
There are already some files for ppc and altivec, but they are not
included since the configuration script doesn't regognize the ppc
architecture the right way.
The other thing is that the assembly files of linux and os x are not
compatible (but the altivec c files are).
What should be done?
I will have a look at the altivec c files if they are still valid and
tell you.
If I made some changes, how can I commit these?
Christoph
