hi,all:

The newest driver of intelfb add VSYNC interrupt support in kernel 2.6.19. i think this ioctl is useful to the people who useing fbdev as video output.

Can we use mplayer -vo fbdev2 -vsync to improve tearing issues?

I don't think it will work in the current design. You'd need to make vo_fbdev2 page-flipped, which would in turn preclude using it in some typical hackish situations that users like, iirc. There should probably be a second page-flipped fbdev vo. Perhaps fbdev2 should be this one and the original fbdev should just be left as-is..?

Also, wait-for-vsync hurts performance a lot. It would be better if the 'page flip at vsync' ioctl works.

Rich Felker, Thanks a lot. What do u mean "make vo_fbdev2 page-flipped"? Would you please make some detail for me? "-vsync" seems not working when i use -vesa:dga -vesa:nodga -fbdev2 as video out. 　　　　　　　　kofboy 　　　　　　　　kofboy@163.com 　　　　　　　　　　2006-11-14
