Using 5.0.6-beta3 and the Send to XBMC/Kodi Firefox addon, the Youtube addon seems to load the WebM version of the video, which has no playable video on the Raspberry Pi. The old Youtube addon mitigated this issue by allowing me to select which quality video (fmt code) to load before playing the video.

EDIT: Commenting out all WebM related definitions per constrainer's suggestion gives the error ' Exception: unknown format for itag "43" '

You can't just remove the mapping for formats I have to look into this after the weekend but this will be difficult, because webm is becoming more and more (especially for DASH) the default for YouTube...I can mostly extract only 2-3 MP4 container and at lower qualities you mostly get webm.
