Video stops in fullscreen

vvvv beta general
#1

hello boys and girls,

experiencing strange behaviour here - when switching to fullscreen my video (1024x768, 5 sec., h.264, ffdshow decoder) stops playing - sometimes immediately, sometimes after several loops. as soon as i alt-enter to windowed renderer video plays fine…? perfMeter shows me solid 60 fps in both renderer modes? any ideas?

probably my nvidia dev drivers for use with NVPerfHud?

system:
windows xp sp3
intel core 2 t7600, 2gb ram
nvidia 7950gtx, driver version: 6.14.11.7815
vvvv40beta20

thanks a lot

are you running your graphics adapter on two heads?

#3

no. i’m not. i know about multiscreen video difficulties, sorry for not stating - i’m on a laptop, no second display connected. have done this lots of times before on my laptop; the only things which changed knowingly is those drivers as well as vvvv version- probably should give it a try with the “normal” drivers again…

might be your problem

yes you’re right - i wonder why i didn’t find this on searching.

setting maximum foreground fps in mainloop to 60 worked out - btw, my video is running at 25 fps, video texture is waiting for every 2nd frame, should i therefore go for 50 fps max in mainloop or is this wurst?

thanks for the help.

“…or is this wurst?”

i’m not sure here, if this results in german sausage :), either set mainloop to the same or double framerate. if wait for frame works with 0 then dont touch the mainloop.

ok, thanks :)
