Windows DVR PostProcess Batch Script for Jellyfin

dvr.bat

@echo off

:: This is the simplest batch script known to man.
:: Takes the unplayable ts_mpeg file from a recorded Live TV program in Windows-Jellyfin and outputs it to h264 mkv, then removes the Transport Stream (NOT Typescript XD) file.
:: This goes in my base Jellyfin folder, sitting alongside the "system" directory per the wiki recommendation for hosting jellyfin on windows.
:: To enable in Jellyfin, navigate to Admin Dashboard->DVR->Select this script file under Post-processing application, and leave the default CLI argument of "{path}" (WITH the quotes).
:: To increase output quality, lower the -crf value and/or change the -preset value to slow or veryslow. Raise the value and change preset to medium or fast for smaller files.
:: All thanks goes to thornbill and his linux script
