Playback continues after pressing pause

[Clausen]

When playing back a project, and pressing the pause button, it takes several seconds before the button changes to the play symbol. After that it takes several seconds before the playback actually stops.

I tried to have a look at the thread priorities.

As far as I could see, correct me if I am wrong, the priorities are as follows (lowest priority first):

- Video caching: 2
- User interaction: 3 (default)
- Audio rendering: 4
- Video rendering: 8

I think user interaction should have the highest priority. Also, audio rendering is, in my opinion more important, than video rendering, assuming that playback simply keeps the current frame if the nest frame is not ready in due time.

My proposal for thread priorities are:

- Video caching: 2
- Video rendering: 3
- Audio rendering: 4
- User interaction: 8

I notice that QThread priorities go from 0 to 6. Priority 7 means inherit the creators priority. Priority 8 is undefined.

My proposal for thread priorities is:

 - Video caching: 3
 - Video rendering: 4
 - Audio rendering: 5
 - User interaction: 6
