hts mkv records,, render to 1/4 size

A script with ffmpeg,, to make records smaler....

#!/bin/bash

# by Christoph , St.Gallen Mai 2024

# Debian 12.x  Debian Bookworm

# hts_render for tvheadend or /home/user/Videos
# Tipp: install first the script and start it plain, to get the help for tvheadend, 
# /usr/local/bin/hts_render \"%f\" mv  wrong, but in help output it will be  /usr/local/bin/hts_render "%f" mv  (this you need then)

# Installation: copy: cp hts_render Script to /usr/local/bin/ , then chmod 755 /usr/local/bin/hts_render, and fix the 
#	the Variables like input path output path etc...
#	ffmpeg must be installed, is recommend/needed.

# The Suffix: i use mkv records, some people like ts more (together with timeshift), i don't know, i never tested.
# 	Maybee with only small PC's you need the ts....?

# Some privat Notice, i keep it
#ffprobe input.mkv 2>&1 | egrep 'Stream #' | wc -l
#fprobe input.mkv 2>&1 | egrep 'SUMMARY'
#`cpulimit -l 650 -- ffmpeg -i input.mkv -map 0:0 -map 0:1 -map 0:2 -map 0:3 -vcodec libx264 -c:a copy -c:s copy output.mkv`

 No Input File..........
 
 $scp_name commands:
 ======================

 Single Files:  $scp_name [inputfile] [cp/mv/rm]      
 Fuel Folder (all Video Files): $scp_name ff [cp/mv/rm]

 Optional [cp/mv/rm]: 
 cp: copy the movie back to Input Path, overwrite, let the -small video in the Output path stay.
	OutputPath/Video-small  (using inputfile name) -->  InputPath/Video
 mv: copy the movie back to Input Path, overwrite, no -small video in Output path.
	OutputPath/Video-small  (using inputfile name) -->  InputPath/Video
 rm: remove the Input Video File, only the -small Video left in the Output path.

 Installation: copy $scp_name Script to /usr/local/bin/ , then chmod 755 /usr/local/bin/$scp_name, and fix the 
	the Variables like input path output path etc...
	ffmpeg must be installed, is recommend/needed.

 tvheadend: Configuration -> Record -> Post Proccesor Command:   /usr/local/bin/hts_render \"%f\" mv   (SAVE!)
	In my Example: (very importend the directory rights !!)
	The Input Path is given by tvheadend:
	drwxrwxr-x  2 hts   video  4096  4. Mai 03:28 hts_recs
	The Output Path i create as root or sudo:  mkdir /home/hts_small;chown -R hts:video /home/hts_small
	drwxrwxr-x  2 hts   video  4096  4. Mai 03:28 hts_small
	Done, now it shut work.
	I use mv, so i overwrite the original video with smaler size, i don't keep the original size.

 Rename this script with a copy of:
	You can copy this script cp /usr/local/bin/hts_render /usr/local/bin/video_render 
	Maybee set the rights, normal they are also copyied, otherwise chmod 755 /usr/local/bin/video_render
	Set the Input/Output Path to:  /home/user/Videos/a_big  and /home/user/Videos/a_small  (as idee)
	So you can use it as normal Video Renderer in your home.

You should embed the script here, otherwise if the server is down or file is deleted at some point in the future, it will be forever lost.

peacok

He leave my Name in topp, it is Flo 😉

peacok

I check out the two scripts,, my one on the topp, and that one from Florian

both work...

In Time, my Script is 3% faster, depends on fixed map Orders....

Florian ones is working same good, he can more hold languaes or subtibles, because i make fix scripts in my file

so i think,, best is ,, you use the last in this posts the script from Florian..

then you stay on the save site 😉

i Love you

Enjoy !!!

peacok

If you want send the Movie over Koaxial or so to a DTV, to a normal LCDTV, is better you use my first script in the post.

So you are shure, no not need infos in the stream.. my LCD TV not like some "HOLES" ... and reboot.

with my first script here in, you don't have the Problem.

This is only important if you reject to an Koaxial DVB-C .. okay

thx
