Revert "Switch to streamio_ffmpeg for easier handling of ffmpeg arguments" This is being done becuase the gem does not support input parameters that are needed for video to jpeg and input format specification when the stream name does not contain the file extension.

This reverts commit 6f1afb5c61245fd6af511ce098d67bfb117f3817.
Merge pull request #17 from psu-stewardship/revert
