// Author: JarBinks

//
// This is my attempt to create an all in one routine that will maintain my library in optimal format !!!!FOR MY REQUIREMENTS!!!!
// Chances are very good you will need to make some changes to this routine and it's partner in order to make it work for you
// Chances are also very good you will need to run linux commands and learn about ffmpeg, vaapi, Tdarr and this script
//
// With that out of the way...Tdarr is awesome because it allowed me to create data driven code that makes my library the best it could be.
// Thanks to everyone involved. Especially HaveAGitGat and Migz whos existing code and assistance were invaluable
//
// My belief is that given enough information about the video file an optimal configuration can be determined specific to that file
// This is based on what my goals are and uses external programs to gather as much useful information as possible to make decisions
// There is a lot that goes into the gather and analysis part because:
// It is the basis of the decisions and "garbage in, garbage out"
// The video files are far from perfect when we get them and we need to make sure we learn as much as possible
//
// The script adds metatags to the media files to control processing, or better yet not doing extra processing on the same file
// This is especially useful when resetting Tdarr because each file gets touched again, so this expedites a full library scan
// Tdarr does not seem to handle when a plugin code takes a while to run so all effort has been made minimize time within the plugin code
// This is especially noticeable on a library reset and these scripts because of the extra time spent analyzing the media files
//
// (TODO: If the file name has non standard characters in it some calls to external programs will fail, I have seen it in about 0.2% of files)
//
// Video: (Only one video stream is used!!)
// The script computes a desired bitrate based on the following equation
// (videoheight * videowidth * videoFPS) * targetcodeccompression
// The first 3 give a raw number of bits that the stream requires, however with encoding there is a certain amount of acceptable loss, this is targetcodeccompression
// This number is pretty low for hevc. I have found 0.055 to be about the norm.
// This means that for hevc only 5.5% of the raw bitrate is necessary to produce some decent results and actually I have used, and seen, as low as 3.5%
//
// If the source video is less than this rate the script will either:
// Copy the existing stream, if the codec is hevc
// Transcode the stream to hevc using 80% of the original streams bitrate
// It could probably be less but if the source is of low bitrate we don’t want to compromise too much on the transcode
//
// If the source media bitrate is close, within 10%, of the target bitrate and the codec is hevc, it will copy instead of transcode to preserve quality
//
// The script will do an on chip transcode, meaning the decode and encode is all done on chip, except for mpeg4 which must be decoded on the CPU
//
// (TODO: Videos with a framerate higher than a threshold, lets say 30, should be changed)
//
// Audio: (Only one audio stream is used!!)
// The script will choose one audio stream in the file that has:
// The desired language
// The highest channel count
// If the language is not set on the audio track it assumes it is in the desired language
//
// The audio bit rate is set to a threshold, currently 64K, * number channels in AAC. This seems to give decent results
//
// If the source audio is less than this rate the script will either:
// Copy the existing stream, if the codec is aac
// Transcode the stream to aac using 100% of the original streams bitrate
// It could probably be less but if the source is of low bitrate but, we don’t want to compromise too much on the transcode
//
// Subtitles:
// All are copied (They usually take up little space so I keep them)
// Any that are in mov_text will be converted to srt
//
// Chapters:
// If chapters are found the script keeps them unless...
// Any chapter start time is a negative number (Yes I have seen it)
// Any duplicate start times are found
//
// (TODO: incomplete chapter info gets added to or removed...I have seen 2 chapters in the beginning and then nothing)
//
// The second routine will add chapters at set intervals to any file that has no chapters
//
// Metadata:
// Global metadata is cleared, I.E. title
// Stream specific metadata is copied
//
// Some requirements: (You should really really really really read this!!!)
//!!!!! Docker on linux !!!!!
// Intel QSV compatible processor, I run it on an i5-9400 and I know earlier models have no HEVC capability or produce lessor results
//
// First off the Matching pair:
// Tdarr_Plugin_JB69_JBHEVCQSV_MinimalFile (JB - QSV(vaapi), H265, AAC, MKV, bitrate optimized)
// Tdarr_Plugin_JB69_JBHEVCQSZ_PostFix (JB - MKV Stats, Chapters, Audio Language)
//
// The order I run them in:
// Tdarr_Plugin_lmg1_Reorder_Streams //I am not sure this is necessary but I have not tested it but it seems like a good idea
// Tdarr_Plugin_JB69_JBHEVCQSV_MinimalFile (JB - H265, AAC, MKV, bitrate optimized)
// Tdarr_Plugin_JB69_JBHEVCQSZ_PostFix (JB - MKV Stats, Chapters, Audio Language)
//
// I am running the docker image provided for Tdarr, however there are some additions that must be added in order for the script to run
// This is to add mediainfo and mkvtoolnix because these are used to get more media info and update the file without running a transcode
//
// Here is my docker config (I am running compose so yours might be a little different)
// Tdarr:
// image: haveagitgat/tdarr_aio:qsv
// container_name: tdarr
// restart: unless-stopped
// network_mode: host
// ports:
// - "8265:8265"
// environment:
// - PUID=${PUID} # default user id, defined in .env
// - PGID=${PGID} # default group id, defined in .env
// - TZ=${TZ} # timezone, defined in .env
// devices:
// - /dev/dri:/dev/dri
// volumes:
// - "${ROOT}/complete:/home/Tdarr/Media:rw"
// - /transtemp:/transtemp
// - "${ROOT}/config/Tdarr:/home/Tdarr/Documents/Tdarr:rw"
// - "/etc/localtime:/etc/localtime:ro"
//
// I then connect to the docker container by using the following command
// sudo docker exec -it tdarr /bin/bash
//
// Here is the script that I run after the docker container is up and running (This requires a couple of (y)es'es to complete)
// sudo apt-get install wget
// sudo wget https://mediaarea.net/repo/deb/repo-mediaarea_1.0-12_all.deb && sudo dpkg -i repo-mediaarea_1.0-12_all.deb && sudo apt-get update
// sudo apt-get install mediainfo
//
// sudo wget -q -O - https://mkvtoolnix.download/gpg-pub-moritzbunkus.txt | sudo apt-key add -
// sudo sh -c 'echo "deb https://mkvtoolnix.download/ubuntu/ bionic main" >> /etc/apt/sources.list.d/bunkus.org.list'
// sudo sh -c 'echo "deb-src https://mkvtoolnix.download/ubuntu/ bionic main" >> /etc/apt/sources.list.d/bunkus.org.list'
