opengl problem on a video player with videoplanes

May 9, 2010 | 8:49 pm


I try to make a simple video player switching between video preloaded in videoplanes (objectvideoplane1, objectvideoplane2,objectvideoplane3 etc)
I drawto a and a window associated.
It works perfectly under max4.6 jitter 1.6 on macOS 10.5 but when I convert the same patch to Max 5 on a PC Window Vista with an intel graphic media video card when I switch from a video to another sometimes the opengl context disappear, i have my video in preview window but not in the main window

in max windows : = using software renderer
and = setpielformat failed -87

does someone has an idea, if it is an hardware problem or something else?

it’s possible the intel graphics card cannot handle some of the opengl things you are trying to do.
