hi i use

ydl_opts = {
            'outtmpl': '/%(title)s.%(ext)s',

@ ubuntu server 14.04. it said file name too long, but this code is fine at MacOS. i want to know how i can output filename with only a specify long (ex: 20 byte).thank you

Hello @orangercat, first sorry for the late response. This problem is already discussed in #5921 and there's no simple and generic solution yet. For Python applications, you can inherit the YoutubeDL class, override prepare_filename() and implement your own filename truncation logic.

I think this is a good advice
