xconv ffmpeg wrapper based on AdvancedAV
-----------------------------------------------------------
AdvancedAV helps with constructing FFmpeg commandline arguments.
It can automatically parse input files with the help of FFmpeg's ffprobe tool (WiP)
and allows programatically mapping streams to output files and setting metadata on them.
