Can ffmpeg.wasm support gltransition or custom GLSL transitions in the future?

[khalifmv]

Is it possible now (or planned in the future) for ffmpeg.wasm to support custom GLSL transitions?

Would it be feasible to:

• Support transition shaders via WebGL in the browser?
• Integrate or simulate gltransition using canvas/WebGL and pipe the result to ffmpeg.wasm?

Just wondering if this is something within scope or worth exploring. Thanks!
