Inspired by https://linuxsuperuser.com/easily-rip-dvds-in-linux-with-ffmpeg/ cat VTS_01_[12345].VOB | ffmpeg -i - -vf yadif -vcodec libx265 -b:v 2600k -acodec mp3 dvd-rip.mp4

If you have home server and want to record streams from your IP camera you can use siple script like this: while true; do     ffmpeg -i "rtsp:// :554/user=admin&password=&channel=0&stream=0.sdp?Real_stream" -acodec copy -vcodec copy -fs 20000000 "/srv/ftp/cam1/vid `date`.mov" | true ; done Option -fs 20000000  limits file sizes to ~20MB CPU usage is very low. Even raspberry pi should be able to save your data from multiple cameras. NOTE: deleting old files is not implemented.
