No video output without serial link #4

What steps will reproduce the problem?
1. Turn on minimosd and video cam/rx, but no APM connection.
2.
3.

What is the expected output? What do you see instead?

When the OSD is powered on with a video signal, but without an active mavlink 
link, there is no video output.

Consider initializing OSD always, and at least pass-through video without 
overlay.

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

MinimOSD just released from diydrones 

Please provide any additional information below.

I expect this is just a case of moving some init code around so that the OSD is 
always enabled first. Thanks!

Turns out I might be a retard.
It dawned on me that telemetry cable is what's supplying digital vcc (which I 
guess is what powers the OSD and AVR), so it's no surprise that the screen goes 
dark when thats unplugged...

I also had a look at the code and it does appear to initialise the OSD straight 
away.
Sorry for wasting anyones time...
