[Bug]: Memory leak, All RAM is eventually consumed over 24-48hrs

[streets97f]

What happened?

RAM memory is filling up slowly over 1-2 days. I've tried using different snapshot presets, different advanced video setting, period refresh rates, etc., but eventually my RAM is completely maxed out over time. This is using a Eufy dual wired doorbell and I've narrowed it down to the Eufysecurity plugin. I do have an IPad that is on most of the day with homekit open and the camera snap shots cycling every 10-30s. If I close the homekit app on the ipad, the memory leak still happens even...just a bit slower.

Hi @streets97f

this seems to be an issue of a new dependency that comes with the latest eufy-security-client: media info.js

They already have an issue about this, but it seems they are also redirecting the responsibility to node: https://github.com/buzz/mediainfo.js/issues/89

I'll get in touch with bropat and see if this dependency is really needed.

Here's the full stack-trace:
