Description

Small convenience improvement: FFmpeg is currently callled without -hide_banner, which is very verbose and can fill up an entire screen. This is wasteful, as many terminal emulators have limited scrollback. The solution would be to include the -hide_banner argument for FFmpeg.

Why is this a desirable feature when you can already pass args to the downloader?

Something like youtube-dl --external-downloader /your/path/not/mine/ffmpeg --external-downloader-args '-hide_banner' or add it to your youtube-dl config file if you want to use it all the time, see https://github.com/ytdl-org/youtube-dl/blob/master/README.md#configuration

I was just thinking that this would be desirable for any user(who doesn't like messing with arguments). I will close this issue if you think it doesn't serve any purpose.
