Problem with HTML5 video is you can use more than just a link to video file https://developer.mozilla.org/en-US/docs/Web/API/MediaSource There are "certain" websites serving videos using BLOB object mediasource created dynamically from encrypted https sources. So far I had no luck trying to capture resulting video datastream, mediasource is a write and forget type of interface, and on top of that MediaRecorder/captureStream() is bugged and crashes so you cant even record lossy reencoded capture.
It's running a script in the background to exfiltrate the info from the browser to the system, and that script has an error. I believe it's a script like /home/dheera/code/clone/TabFS/fs/tabfs* – if you look around in the browser some more you should find the stderr output of the script, which probably explains the error
Unfortunately it doesn't work for me though -- I get "Unchecked runtime.lastError: Native host has exited."
