Can not be installed on Heroku
When i tried to push my application to Heroku it cant install the av_capture gem.
How to install/use?
I tried installing the 2 gem needed in the Rakefile and ran rake.
But seems like I need to compile something? What steps am I missing?
gem install hoe rake-compiler
rake
Defaulting gemspec to MIT license.
Call license in hoe spec to change.

Add Development dependency for minitest?
I know it's just a pet project but it may be worthwhile to toss minitest into development.
Know that my rake failed because of minitest missing. Granted everyone who can read would be able to figure out they need to gem install minitest
Only taking blank black pictures :(
ruby: 2.3.0
av_capture: 1.0.0
Is 2.0.0 *really* required?
Hey TL-dawg, I'm using this gem in my frame-capture-over-time gem gorthaur and we're trying to make the thing as accessible as possible.
One hiccup (as you might imagine) is the Ruby version. Right now av_capture is the gem that sets the lowest bar (2.0.0) and we're wondering if that's as low as it can go. Is there anything I should know before I dive in and try to make it compatible with lower versions of Ruby? Is this even desirable for this project?
Does not work on Yosemite
When calling simple script which save an image it crash during capturing in this code
image_binary = AVCapture::Session.new.run_with(d) do |connection|
connection.capture
end
with this call stack
"devices [#<AVCapture::Device:0x007fc56a8f8900>]"
"device FaceTime HD Camera (Built-in)"

But it is probably issue of Yosemite because other utils does not work too. On Mavericks it worked OK.
