Description

Currently when downloading HLS stream from .m3u8 file you get all console spammed with loads of

[https @ 0x557f165b4b40] Opening 'https://server/file.mp4/segmentXXXX_0_a.ts' for reading  

I want to silent them so that I can still see download progress. If I use -q then there's no progress information anymore.

So basically what I want is -q --progress so it's quiet but with progress information.

If I'm not mistaken that message actually comes from ffmpeg. You could pass -loglevel warning to ffmpeg via --external-downloader-args

What is the parameter for that? only --external-downloader-args?

There are examples of its usage in other issues here. GitHub's built-in search will find them.

Awesome, so turns out everything is done by ffmpeg.
Using just -loglevel warning didn't work because it also hide progress, but this works perfectly and is exactly what I needed:
youtube-dl --external-downloader-args "-loglevel warning -stats"

I guess it would be nice if youtube-dl had flag for this case (quiet but with progress) but it's not really issue as can achieve it anyway.
