Add thumbnails for the list of videos

[schedutron]

Currently, the videos are listed with just their names. It would be awesome to have their thumbnails beside them.

@Kalwing Wanna do something here?

Sure. Is there a way somehow to generate thumbnail image file with python ? Because otherwise I could probably put the video and just remove the control. so it would appear to be just an image. The problem is that it would force the brother to load more data. So it's not ideal !

Edit : It appear that I can't prevent the browser from loading the video. still not perfect as it is not semantically correct to use a video as an image (and it can be problematic for accessibility) but it would works
