Fixed

Direct links without a file extension were considered audio. The player showed as a black screen. Now, direct links are considered video by default unless the extension matches the audio file extensions.
User grade was not updated when it decreased to 0. Now, if the grade is 0, it will be removed from the gradebook.
When "Autohide controls" was set, the control bar was also hidden in embed mode. Now, this setting is only applicable in default mode and distraction-free mode.
