[lucascharrierpulpix]

Trying :
youtube-dl -f worst http://www.dailymotion.com/video/x28gvoz_dr-mietzsche-la-verite_school --verbose

I get the following output:

[gaming-hacker]

i wonder if it is because you have

'Accept-Language: en-us,en;q=0.5

and the file name is french with special characters.

la vérité-x28gvoz.mp4

try adding the flag to get rid of characters

--restrict-filenames

[denisvlr]

I'm getting a similar error: the command youtube-dl -f worst http://www.dailymotion.com/video/x28gvoz_dr-mietzsche-la-verite_school --verbose returns the following error:

https://www.dailymotion.com/cdn/manifest/video/x28gvoz.m3u8?auth=1446385706-2562-ok82k369-2570de0c022779c9c6e74c31a4f0700e: Protocol not found ERROR: ffmpeg exited with code 1
(and then the same stack trace)

Adding --restrict-filenames didn't fix the issue, I also tried videos in english with regular characters.

The option -f best works correctly however.
