plex-ffmpeg

This image builds off the official Linux Server Plex repo whenever there is a new release version. It adds ffmpeg that can be used with a post processing script with the DVR.

Example Post Processing Script

If the script below is called PlexPostProc.sh, this script will need to be mounted to /config/Library/Application\ Support/Plex\ Media\ Server/Scripts/. The script is a modified version pulled from PlexPostProc.

#
#            Plex DVR Post Processing w/ffmpeg (H.265) Script
#
#****************************************************************************** 
#****************************************************************************** 
#  
#  Version: 1.0
#
#  Pre-requisites: 
#     ffmpeg
#
#
#  Usage: 
#     'PlexPostProc.sh %1'
#
#  Description:
#      My script is currently pretty simple.  Here's the general flow:
#
#      1. Creates a temporary directory in the home directory for 
#      the show it is about to transcode.
#
#      2. Uses ffmpeg (could be modified to use handbrake or other transcoder, 
#      but I chose this out of simplicity) to transcode the original, very 
#      large MPEG2 format file to a smaller, more manageable H.265 mkv file 
#      (which can be streamed to my Roku boxes).
#
#      3. Copies the file back to the original filename for final processing
