But even if you'd don't use AWS use something else. Any video encoder service will be cheaper and more reliable than using k8 + your own hacked together docker instance. It's literally not worth it. Do you really want to spend your time messing around with ffmpeg and setting the correct GOP values? Or trying to create your own b-frame track? At some point you actually need to do what all these settings are for. Until that time you should use other services.
