How to get rid of ffmpeg showing `configuration:` message?
Solution 1:
You can use the global option -hide_banner:
ffmpeg -hide_banner -i video.ts -c copy video.mp4
Note that this is a cursed option: if you ask for help and include -hide_banner it will hide very useful info. You will then be asked to omit this option and resubmit your command and the complete console output which will delay you getting an answer.
