Error trying to play Youtube streaming (using gmmp-plugin-pack-youtube)

[RafaelLinux]

I have openSUSE Tumbleweed with QMMP and qmmp-plugin-pack , qmmp-plugin-pack-youtube, but when I try to play a Youtube stream (like https://www.youtube.com/watch?v=-cABBWfRqms), it doesn't work, giving an error ("error" is showed in bottom left playlist corner) and this is the console output:

How to fix this? Could it be I'm using a proxy? I can play icecast and shoutcast streams without issues ....

Thank you
