Using WebMWriter inside a WebWorker

[dayaftereh]

I would like to use the WebMWriter inside a WebWorker, but I get the exception

'window' is not defined

Some digging in the code I found that window is used at:

webm-writer-js/src/WebMWriter.js

Line 43 in 62cc832

return window.atob(url.substring("data:image\/webp;base64,".length));

Changing the line to:

return self.atob(url.substring("data:image\/webp;base64,".length)); 

solved the issue.

@dayaftereh Do you get better performances?

[dayaftereh]

@nuthinking I haven't measured the performance yet. I'm transfering a video frame by frame to the WebWorker. A the WebWorker I run some green screen removing and 2d particle simulation by redraw everything with an offscreen canvas. I do all the stuff at the WebWorker to keep the Main-Loop responsive.

I don't need the main loop to be responsive, but I really need to find ways to speed up the recording. See #40 . Any tips on how to move it to a WebWorker so that I can test it? If passing the same frame to multiple workers doesn't take many milliseconds. I might be able to cut the time needed by half. Thanks!
