[MPlayer-dev-eng] [PATCH] New VO drivers.

[Ivo]

Second reply to my own e-mail ;)

Anyway, I have re-implemented both vo_pnm and vo_md5sum. Now, they don't 
maintain a local copy of the current frame when in YV12 mode, don't use 
draw_frame() or draw_slice(), but act on VOCTRL_DRAW_IMAGE and the 
mp_image_t * that's passed on to it. Huge improvement in speed and memory 
usage for yv12 modes (pnm:pgm, pnm:pgmyuv and when yv12 data is feeded to 
md5sum). Also, I added almost paranoid error checking. If something goes 
wrong, it is detected and handled.

Any comments, objections or suggestions to/on this code? If not, I will 
commit it in a few days.

I will leave vo_pgm and vo_md5 intact for the moment. What path do we have 
to follow to remove these (since they become obsolete)? To keep the user 
informed, the only way I see is to delete all content of the functions 
inside those vo drivers and have preinit() write a message to the console 
and exit the player.

Oh, and I will update the manual page after commiting the code :)

The new non-diff files attached to this e-mail should be placed in 
main/libvo/.
