#!/bin/bash
# This script will search provided folder and find all invalid mkv files in it that does not contain x264 video stream
# For example file with mkv container contains mpeg4 or XVID stream
# After it finds those invalid files will execute the transcoding on them

# expected video codec is h264, it can be changed
# if no expected codec found then the transcode will arise
