Hi
I have made a modification on protectionController to avoid too many calls to eme protection system (this can lead to a crash of CDM). Can you try the code available in PR #2165 please ?

Hi @NyuuuuOrz, did you have the time to test whether @jeremco changes fixed this issue?

I am sorry to have kept you waiting. I have tried the code modified by @jeremco but it seems have no effect. The Widevine Content Decryption Module still crashed. I also notice that after a long time widevine live stream playback, the Firefox browser will use lots of resources of computer(about 75% memory and 65% CPU of a Core i3 CPU/4G RAM computer), which will lead the playback more and more lag.

No problem @NyuuuuOrz and thanks for your feedback. I think the code modified by @jeremco is usefull but not enough.... :-(
In Firefox browser, debug console is it opened when you measure performances?

[NyuuuuOrz]

No. During my test I have closed the Dash.js debug console and the browser console
