@hackage ffmpeg-light0.3.0.1

Stream frames from an encoded video, or stream frames to a video output file. To read the first frame from an h264-encoded file into a JuicyPixels Maybe DynamicImage,

import Codec.FFmpeg
import Codec.Picture
import Control.Applicative
import Control.Monad.Trans.Maybe

go :: IO (Maybe DynamicImage)
go = do (getFrame, cleanup) <- frameReaderT "myVideo.mov"
        (runMaybeT $ getFrame >>= toJuicyT) <* cleanup

Tested on OS X 10.9.2 with FFmpeg 2.2.1 installed via homebrew.
