Re: [Freevo-devel] Re: Mplayer bmovl helper

[Per Wigren]

rgba32_data = pygame.image.tostring(surface, "RGBA")

I can imagine doing that conversion in python is painful, but there
sould be a way. I'll look for it in pygame docs, maybe someone could
ask for it there?
or, as you said, do some extern C code to do that, maybe with mmx and
stuff.
however, if you can get myscreen->surface and myscreen is RGBA, it's
done.

How/Why is it slow?

is the bmovl slow? Is our interface with it? Maybe we can come

a
       

better solution somewhere...
         

We have to transform the SDL surface into a RGBA32 stream. This is
very slow in Python, maybe a C helper with python bindings can do
this
faster (very sure, because the biggest problems seems to be the
memory
management). 
       

PyGame doesn't do that in C? Getting a RGBA from SDL is just a
     

matter
   

of  (int32_t *)mysurface->surface
     

There is no function to convert a surface into RGBA (at least I found
none). So a made one myself in python and this is really slow.
