There is a lot of confusion about the fact that the HTML editor offers two video plugins: the standard plugin which writs HTML 5 video tags and the OpenOLAT video plugin which can deal with all kind of formats, streaming etc.
The goal is to have only one video plugin, the OpenOLAT video player. The standard video plugin offered by TinyMCE should be removed. Videos created using the standard plugin should be editable with the OpenOLAT plugin if possible.
The OpenOLAT plugin can also deal with Vimeo videos, however this info is missing in the UI. An additional help button which opens the video section in the manual would also be great.
