Allow MP4 to Play in Ubuntu 20.04

Refer: https://linuxconfig.org/unable-to-play-the-file-missing-decoder-on-ubuntu-20-04-lts-focal-fossa

Error Message when trying to play MP4:
Video mp4 dvd subpicture decoder is required to play the file but is not installed

sudo apt install -y vlc
sudo apt install ubuntu-restricted-extras
sudo apt install libdvdnav4 libdvd-pkg gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly
sudo reboot

Older notes: Don't think these fixed anything; however, you do need to install VLC standard

Refer: https://itsfoss.com/play-dvd-ubuntu-1310/

These commands don't really do the trick:

sudo add-apt-repository multiverse
sudo apt install -y libdvd-pkg
sudo dpkg-reconfigure libdvd-pkg

Important: You need to install VLC from command line and NOT Snap version

sudo apt install -y vlc

Convert MP4 to MP3 on Ubuntu 14.04 Trusty and Tag Meta Data Software

There is a program available on Ubuntu youtube-dl, that can download videos from youtube.com or other video platforms. But it stores the file in mp4, since it contains video. But sometimes you do not want the video and only the audio. To extract only the audio part, you can use the pacpl comamnd line tool.

Use "Sound Converter" Application for simple conversion

Usage:

$ youtube-dl -f mp4 --output "yourfilename.%(ext)s" https://youtu.be/your-link-here
$ youtube-dl --extract-audio --audio-format mp3 --audio-quality 256 --output "yourfilename.%(ext)s" https://youtu.be/your-link-here

Older Method:

pacpl --to mp3 -v -r -bitrate 256 targetfile.mp4
