Trying to play partially processed videos from "my videos" page stops the encoding.

What steps will reproduce the problem?
1. Upload a video
2. Click "view" from "my videos" page before it's finished processing

What is the expected output? What do you see instead?
It will play the video up to the point of how much it had encoded when you hit 
view, however this stops the encoding process and it will never play past that 
point, ever.

I assume it's likely a problem with ffmpeg not liking that a second process is 
accessing the output flv at the same time. This should be a dead simple fix by 
just disabling the link to view from "my videos" until processing has finished. 
This will prevent accidents.

What version of the product are you using? On what operating system?

Please provide any additional information below.
