I'd recommend at least trying fbtv as it _might_ be faster as all it should be doing is just taking the data from the camera and blitting it to the framebuffer. mplayer2 probably has more steps in the way (even though it's probably much more optimised) and as I don't know how the sunxi VDPAU driver works I can't comment on whether or not it'd be faster. Source is available at: http://git.linuxtv.org/xawtv3.git and if you're using an actual distro, it should be packaged for it. (Debian / Ubuntu have it packaged in the main archive, not sure about Fedora) Thanks, -- Julian Calaby Email: [email protected] Profile: http://www.google.com/profiles/julian.calaby/ .Plan: http://sites.google.com/site/juliancalaby/ -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
