I have a small old CPU and a GPU that doesn’t support video encoding, so don’t even consider the fact that I have a GPU. (Just because, it’s an NVIDIA GeForce GT 730.) My CPU is an Intel Core 2 Duo E8400 (2) @ 3.000GHz.
I have one hundred and nine 5184*3888px JPEG pictures that I want to scale down in FFmpeg. Running ffmpeg -i *.JPG -vf scale=1296:972 *.JPG results in my computer bugging completely. I can’t move my mouse, escape the program, nothing. This happens after I’ve confirmed that I want to overwrite files with the same names. Since I could see no files had been changed after I rebooted my computer, I’m assuming FFmpeg did not output anything before stalling. I’ve attempted the procedure several times, and I get a frozen computer every time.
How do I tell FFmpeg to “take it slow” rather than filling up my CPU, and could you estimate a good setting that I should use for optimal performance?
I’m running Debian GNU/Linux 11 (bullseye) x86_64 on an HP Compaq 8000 Elite CMT PC.
