+Server script by @uo0Evx99@mastodon.cloud used on a Raspberry Pi 3 B+ to convert recordigns to mp4 files:
+```
+#!/bin/bash
+
+#
+#Explanation of the code: It first takes all the .ts files (because sadly the server
+#doesnt save the video in 1 big file instead) and creates one big .ts file in the same
+#folder called "all".
+#
+#Then it uses ffmpeg to re-encode the .ts file to .mp4 while just copying the audio
+#and video codec to reduce the encoding time. It also uses the -movflags faststart so
+#the video can be played back instantly when viewing online (e.g. with Plex)
+#That re-encoded file is being stored in the folder /home/pi/hdd/plex/"MODEL NAME"/ 
+#with the name "CURRENT TIME"-"MODEL NAME".mp4
+#
+#Then it deletes the folder in which all the .ts files were, because we dont need
+#those anymore as we have our .mp4 file re-encoded already and ready to use/stream.
+#
+#This script has been used on a Raspberry Pi 3 B+

+# $1 directory (absolute path)
+# $2 file (absolute path)
+# $3 model name
+# $4 site name
+# $5 unixtime

+# format unixtime to human readable
+TIME=$(date --date="@$5" +%H:%M_%d.%m.%Y)
+
+cat $2/*.ts > "$2/all.ts" && ffmpeg -i "$2/all.ts" -acodec copy -vcodec copy -movflags faststart "/home/pi/hdd/plex/$3/$TIME-$3.mp4" && rm -r "$2"
