Hello,
I have a task to program. Some PAL (or NTSC) resolution square-pixeled
8-bit planar RGB data will arrive by an awaitable DMA handler. I need to
visualize this data at the primary screen, non-interlaced 768x576 ,
preferably at 100 Hz. and at the same time at TV OUT in recordable
(bcast) quality.
I have a Matrox G450 32MB DH. I made mplayer work perfectly showing PAL
DV data on a TV monitor using 0.9.23 on Debian Sarge. But this costs me
the primary screen I guess because of redirecting the Back End Scaler. I
don't need BES! I don't need any kind of conversion whatsoever. I simply
need to use the same databuffer for both heads. Data is ready or just
needs planar packed conversion.
Is this possible to do it with DirectFB?
If not, I am willing to add this functionality myself. I wish to be
directed to a nice starting point by the developers. As far as I
understand out of various methods around the web it MUST be possible for
upto the largest scannable PAL 1023x625.
Instead of planar->packed conversion would it be more viable to use 3
different alphas each for RGB planes for colorizing and blending them?
Or does DRI or GL accept planar RGB via AGP as texture ? Can such a
blend or texture be rediectable to TV OUT?
I already bought a G400 DH too. If that's driver is more capable than
G450 it is fine as well.
Please tell me if developers list is more proper to ask this.
Thanks for developing and using DirectFB!
Cagdas
