Error spam while downloading Periscope

[gaussey]

My console is getting Invalid DTS and invalid timestamp errors while downloading from Periscope (live) to the point where I can't see the name of the stream downloading. I suspect those errors are coming from ffmpeg. The captured files are fine, I just want to quieten the output, I've tried sending youtube-dl -i and -q with no effect.

Please post the full verbose log with -v.

and it repeats until interrupted.

[yan12125]

Sorry but such errors are caused by problematic files served by Periscope, while it's a good idea to supress errors from ffmpeg with -q. Is it OK for you?

[gaussey]

I've tried adding -q to the youtube-dl parameters and it has no effect, is there a way of setting ffmpeg to always use -q? I can't find any documentation on a config file.

[yan12125]

This is not implemented yet.

[Vrihub]

is there a way of setting ffmpeg to always use -q

Yes, you can add this option to your youtube-dl command line:
--external-downloader-args '-loglevel 16'
so youtube-dl will pass -loglevel 16 to ffmpeg: this will suppress ffmpeg warnings often caused by periscope streams.

You can find more information on -loglevel in the ffmpeg man page.

[gaussey]

Thanks, that works perfectly, quotes need to be full (on Windows at least).
