mapping tools GsVideo ControlP5 Flickering Texture

in Contributed Library Questions • 1 year ago

Hey,

im having a problem with the mapping tools library and the controlP5 library.

Im not quite sure if its them, or if the problem is anywhere else.

the setup is that i want to use a beamer and my monitor.

ive a "GLTextureWindow" in which i load a texture which is filled with a video of the GsVideo Lib

this texture is rendered in a freeWarp Object

i draw them twice

once in the monitor and once in the beamer – that kinda looks like that

void draw() {
if (mov.available()) {
background(0);
mov.read();
if (tex.putPixelsIntoTexture()) {
if ((mov.duration() - mov.time()) < 3) {
println("END OF VIDEO");
goToNextActive();
mov.delete();
mov = new GSMovie(this, path+"/"+filenames[globalVideoCounter]);
// delay(800);
// if (mov.available()) {
mov.read();
// }
mov.setPixelDest(tex);
mov.play();
}
if (mode == 0) {
if (calibration) {
qw.showControls(true);
qw.render(logo);
}
else {
qw.showControls(false);
qw.render(tex);
}
canvas.beginDraw();
canvas.clear(0);
background(0);
if (calibration) {
qw.showControls(true);
qw.render(logo);
}
else {
qw.showControls(false);
qw.render(tex);
}
canvas.endDraw();
}

everything so fine this far –

no Problems

BUT –

for some reason if i draw my ControlP5 on the monitor – the texture starts flickering

if i hide the controlP5 – everything is fine …

as far as i know the same thing happens if i try to write text on the monitor …

does anyone have an idea what this could be about … and if its fixable or somewhere deep in the libraries?

Thanks

My guess is that you're running the sketch on a different framerate than the actual video, and if mov.available() aint true it will not render anything.

Remove the if-statement "if (mov.available()) {" and see if it works better.

Edit:

Same could be said about " if (tex.putPixelsIntoTexture()) {", since it can also be false. Only run "tex.putPixelsIntoTexture();" without the if-statement, since it does the same thing.
