[sdljava-users] YUV Overlay

[Pedro R. <bi...@ya...>]

Hello.
I'm trying to play a xvid video with SDLjava.
So I've made:

Runtime.getRuntime().exec("/sdljava-0.9.1/mencoder -of
rawvideo -ovc raw -vf format=rgb32 test.avi -o pipe");

Then I open screen ByteBuffer:
p=screen.getPixelData();

Read the pipe...

and screen.flip();		

Works but It's slow, so I think that using YUV overlay
it'll work faster.
So I'm interesting to know how can I use the sdl yuv
functions like SDL_DisplayYUVOverlay.

Nevertheless, if anybody knows another way ...

Thanks

Greetings,

Right now there is no working support for the YUV overlay stuff.  Its=20
almost there though.  I recently added the code to support it.  Except=20
there is one part that is not working so it won't be much good until=20
that is resolved.

The problem in queston is line 207 of SDLVideo.i -- In the call to=20
NewDirectByteBuffer I am not sure how to implement the size=20
calculation.  Right now its saying a size of 1.  If this line could be=20
corrected then I think the YUV stuff should be working.  You could=20
access the YUV functions via SDLVideo and SDLOverlay classes.
