So I needed to record a phone call over my Google Voice today and decided to use OBS despite me not being an expert in the program it is the one I have most recent experience with.
Elsewhere it was suggested to use Audacity for audio only streams, but I couldn't figure out before my call how to capture both input from my mic and output from the headphones.
Anyway, I did a quick test capturing both configured audio sources before my call and it seemed to work fine. I had disabled any video capture by checking off the "eyes" on all video sources.
Call lasted about 100 minutes and it took about 45 minutes after the call was done for the recording to stop. To be clear I clicked on stop immediately, but it was stuck in the "Stopping Recording" state.
During this time it appeared that the output file was still being written to (growing in size), and when I checked Task Manager OBS was only using < 10% CPU but appeared to be using about 85%+ GPU (as a side note as I sit here with OBS idling, i.e. not recording, it still shows ~10% GPU usage).
After 45 minutes it appears to have finished, but I'd like to understand what is going on here and if there is a way to prevent it.
I realize that even though I am not capturing any video streams that it must still be trying to encode my empty video into the resultant MP4 output file.
But, for audio only this seems unnecessarily time consuming. Is there a way to prevent this if I need to do this in the future?
thanks
