Render transitions as AVI?

[malteos]

Hi everyone,

is it possible to render a slideshow made with glsl-transitions as AVI or any other video format? I would like to render the slideshow server-side not with canvas.toDataUrl() in a browser.

Cheers
Malte

Hi @mschwarzer ,

It is not currently possible because not implemented.

I agree this would be great and technically this should work (WebGL GLSL can be compiled to OpenGL GLSL via ANGLE).
I've started this discussion one year ago on this thread: gre/transitions.glsl.io#56

Which currently leads to a beginning of implementation of a plugin for "MLT" started by @rectalogic but it is unfinished.

• Best would be to natively implement some plugins to MLT/ffmpeg or any other tool but it takes a lot of time to make it.
• Another approach might be to try to "emulate WebGL" but this is quite uncertain and probably slower.

This is open to contribution.

Thanks
