When downloading a track off soundcloud with an umlaut in its title (e.g. äöü) and the flag --embed-thumbnail ffmpeg fails to add the thumbnail to the track and exits with the error 'No such file or directory' even though the thumbnail has been downloaded successfully by youtube-dl.

Tested on win8 with cygwin

Does it work for songs without umlauts?

[yan12125]

By the way, this looks like a duplicate of #7238. Please consider updating ffmpeg.

It does, that's why I specifically mentioned that the problem only occurs when downloading tracks with umlauts in their title.

Please consider updating ffmpeg.

I have version N-76684-g1fe82ab installed at the moment, will look for an update now.

Update: Fixed by updating ffmpeg (thanks @yan12125) to the latest build 11777eb (2016-09-19), sorry for not thinking about that beforehand.

[yan12125]

No problem. Glad to see that fixed!
