# conv2mp4 - https://github.com/BrianDMG/conv2mp4-ps v1.1
#
# This Powershell script will recursively search through a defined file path and
# convert all MKV, AVI, FLV, and MPEG files to MP4 using ffmpeg + audio to AAC.
# It then refreshes a Plex library, and upon conversion success deletes the source
# (original) file. The purpose of this script is to reduce transcodes from Plex.
