Hide video playback controls earlier

reported via mail:

Video playback is very difficult. This was also an issue in previous versions of Nextcloud Talk. When you click to watch a video, it opens dimly and with navigation buttons in the middle, which greatly hinders the viewing of short clips. After 5-6 seconds, this disappears.

The bot sends short video clips from the cameras to the chat. And there’s always a darkened area with navigation buttons in the middle.

i will decrease the time to hide the controls.
However this escalated in some more improvements. PR will follow
