Video Transcoder

Mar 29, 2018

Changes in v0.6:
- Use foreground service for managing FFmpeg to allow encoding of files longer than 10 minutes.
- Cancel in-progress encodings if service is destroyed, preventing encoding from continuing without a way to cancel it, and an application crash when the encoding completes.
- Create destination directory if it does not exist.
- Change the output filename to be based on the input file name.
