Hi,
I'm working on a new object to play video and draw them directly into a frame buffer (I'm using libvmpv[1] to do so). This object will be publicly released on the end of august. In the meantime, I have optimisation trouble. The object inherit from gemframebuffer object and I would like to redraw on the fbo only when a new frame is available, for performance reason. But in my render() method,if I do not call gemframebuffer::render() then I get in the Pd's console :
GL[1284]: stack underflow error
I'm wondering how I can get rid of this ? i.e. returning render() method without calling gemframebuffer::render() ? If I call it without drawing the frame, then the fbo is black. If there is no new frame I just want to reuse last texture.
Best
Antoine

most likely (i haven't looked at the code...) you will also have to override the gemframebuffer::postrender() method.

this is what I missed, thanks
