While I was writing a shell script (doing this the past several days) just a few minutes ago my PC fans spinned up without any seemingly reason. I thought it might be the baloo process, but looking at the running processes I see it’s names block-rate-estim . It takes 6.2% CPU time and is running since minutes, on my modern 8 core CPU. And uses up 252 KiB. The command is shown as block-rate-estim --help, which when I run on the commandline myself will just run the program without output and blocking until I end the process. Sounds alarming to me first. Is something mining going on?

I looked up where the command is coming from:

$ ls -l /usr/bin/block-rate-estim
.rwxr-xr-x 14k root 20 Dez  2023 /usr/bin/block-rate-estim

$ yay -F block-rate-estim
extra/libde265 1.0.12-1 [installed: 1.0.15-1]

It’s still going on the background, I have no idea what this is. The thing is, I didn’t start any process that is related to video codec. Other than FreeTube being in the background with video in Pause mode since 2 hours or so. I use FreeTube since months and this never happened before, I see this block-rate-estim process the first time.

What should I do? I’m on an up-to-date EndeavourOS installation.
