[fixed] WebM videos are not fully read

[spaii]

Started a project with Pastis (it's his login name, not a bottle in front of me ) concerning all possible figures in stunts mode.

I realised that WebM video are not completely read until end of video.

To test:
1. Go on "stuntips" manialink (W.I.P)
2. Then click on "Show Aerial on Canyon"
3. Wait for video loading (no progress bar for now)
4. video is playing, but not totally

You could compare with the online version, which is same as in manialink :

Thx

Edit: BTW, there is a strange jerk on maniaplanet that is not visible on internet browser (mine is Chrome)
Video is at 1920*1080 and 30fps

Fixed concerning "WebM video are not completely read until end of video".

Jerk still present
