Preserving metadata from the first input file when concating #5

Closed TheMetalCenter closed 2 years ago

TheMetalCenter commented 2 years ago

Currently metadata from the original split files is lost when concating because ffmpeg doesn't know to grab from first file when using a list of files as input.

This is a convoluted method (using rxrepl as a search and replace engine) that seems to work to get around this, but going to test more before comit. The original ffmpeg string is just commented out so it can be easily restored if necessary.
