Fix: video player

[PaulLerner]

Hi,

I already opened issue #60 which is related but I think it's better to have a clean issue here (I'll close #60).
I noticed several bugs :

• Clicking on the waveform is ineffective
• It gets all white like this :
  
• Sometime the regions doesn't display at all, although this happens only on one of my two machines (both have ubuntu 16.04 and run gecko in firefox) :
  • doesn't happen on my laptop witch has :
    • npm 6.12.0
    • node v12.13.0
  • happens on my work computer which has:
    • npm 6.11.3
    • node v12.11.1
• Can't jump regions in video mode, I fixed it here : https://github.com/PaulLerner/gecko/tree/fix/video (Should I PR ?).
• Can't playregion in video mode, I wasn't able to solve it with the same trick as my fix/video. The player gets stuck in the same frame and audio and video get out of sync

Have a good week-end,

Hi Paul, thanks

Working on it

The bugs were fixed.
In the future we will change the video display to a more comfortable component
