You have to run them at paint time, and you're blocked waiting for painting then. 61466 2 chuck 2011-12-12 23:23:39 +0000 The "MediaStream Processing API" proposal offers an example of Workers for audio processing. The document does not tackle video processing though it does offer the idea of <canvas> processing in the examples section. It's noted that video data should be added in a subsequent draft to the ProcessMediaEvent. https://dvcs.w3.org/hg/audio/raw-file/tip/streams/StreamProcessing.html#worker-processing Shaders may be used for audio processing, this is an area where the CSS Shaders proposal and the MediaStream Processing API have some possible overlap. GLSL can be used for Audio effects, and JS can be used for image effects. 81322 3 dschulze 2013-01-14 07:27:37 +0000 (In reply to comment #2) > The "MediaStream Processing API" proposal offers an example of Workers for > audio processing.

I agree with Simon that it does not make any sense to combine WebWorkers with CSS Shaders. I close this bug for now.
