Install

Uninstall

For some reason, after I uninstall VLC, sudo apt update or apt list --upgradable still prompts to install some vlc-related packages like libvlc-bin. But I can remove it by sudo apt purge --auto-remove libvlc-bin

How to play DVDs

https://help.ubuntu.com/community/RestrictedFormats/PlayingDVDs

Rip DVD

  • My experience
    • Install Linux Mint + Multimedia codecs. Ubuntu Studio even cannot play the DVD using VLC.
    • GRUB2 generated from Linux Mint installation will 'automatically' include Windows OS installed on another disk.
    • Make sure "libdvdcss2" package has been installed.
    • Use sudo + dd to back up DVD to an iso file; something like, sudo dd if=/dev/cdrom of=DVD.iso bs=2048 status=progress. If we ignore sudo the iso file size is very small (~150MB) instead of 7-8 GB. We may need to run chown on the iso file to return the owner of the file to the user. It took about 10 minutes when I used bs=2048 option (12MB/s).
    • For some unknown reason, directly run the "sudo dd" command will result in 150MB iso file (no error came out). I need to let VLC to play a little bit of the DVD and the "sudo dd" command will work successfully.
    • The DVD.iso can be mounted by right clicking the iso file in the file manager (Linux Mint and Ubuntu GNOME have different names. In Linux Mint, it is called Archive Mounter. In Ubuntu GNOME, it is the 1st option Open with disk image mounter. VLC can play the "DVD" by selecting the mounted location instead of the regular DVD location ("/dev/sr0"). The subtitles can be selected in VLC as if we have the original DVD.
    • DVD seems to have a resolution of 480p only.

“VLC is Unable to Open the MRL” Error

Fixing “VLC is Unable to Open the MRL” Error [Quick Tip]

Stream Local Videos

Find TuneIn streaming URL

Follow this video, I can get the streaming url of WQER Chinese radio.

  1. Right click and select inspect
  2. On the right panel, select 'Network' tab
  3. Pay attention to the row with long 'Waterfall'
  4. Right click and select copy -> copy link address

This method also works to find out the cbsnews/live streaming URL (https://cbsnhls-i.akamaihd.net/hls/live/264710/cbsn_hlsprod_2/master_360.m3u8). I can watch the streaming in VLC.

The method does not work on Enlightened Piano Radio which uses html5 mp3 driver. The website has an advantage of showing currently playing songs.

Sniff out the link

Video Download Helper (Firefox Add-on, 2.7M users). It works to find

Video Downloader professional (Firefox Add-on, 292K users) also has a good number of users and reviews.

Playlist

The internet streaming I played will be automatically added to LIBRARY > Playlist. These stations will be gone once I quit VLC unless I save the playlist (eg <vlc_playlist.m3u>).

Docked playlist

On Linux, View -> Check 'Docked Playlist'.

On Mac, I don't find a similar option.

Addons

Use VLC to listen tunein radio

Download link http://addons.videolan.org/content/show.php?content=152788. Click the download button to download the file "TuneIn-Radio-VLC-master.zip". Unzip it. A new folder "TuneIn-Radio-VLC-master" will be created. 

curl -L https://github.com/diegofn/TuneIn-Radio-VLC/archive/master.zip > TuneinRadioVLC.zip
unzip TuneinRadioVLC.zip

Create two new subfolders and place the lua files

  • move the “tunein.lua” file to the VLC folder so it can be found and run by VLC.
    • In Linux, move the “tunein.lua” file to ~/.local/share/vlc/lua/sd/ 
      mkdir -p ~/.local/share/vlc/lua/sd/
mkdir -p ~/.local/share/vlc/lua/playlist
cp TuneIn-Radio-VLC-master/tunein.lua ~/.local/share/vlc/lua/sd/
    • In Windows, move the “tunein.lua” file to %AppData%/VLC/VideoLAN/lua/sd.
    • In Mac OS X, move the “tunein.lua” file to VLC.app/Contents/MacOS/share/lua/sd 
      sudo cp TuneIn-Radio-VLC-master/tunein.lua /Applications/VLC.app/Contents/MacOS/share/lua/sd/
sudo cp -R TuneIn-Radio-VLC-master/playlist/* /Applications/VLC.app/Contents/MacOS/share/lua/playlist/
  • move the “radiotimes.lua” and “streamtheworld.lua” files from the Playlist folder to “/lua/playlist” folder in the VLC directory. 
    cp TuneIn-Radio-VLC-master/playlist/* ~/.local/share/vlc/lua/playlist/

Close and open VLC. Go to “View -> Playlist”. At the sidebar, under the Internet section, you should now see “TuneIn Radio” in the list. Click on it and you will be able to access your Favorites.

Note that

  1. the TuneIn Radio will be LOST once I upgrade VLC (tested on Mac).
  2. on Linux, right click menu has an item called 'Information'. The 'Codec' tab will show the Location (IP address) information. Mac VLC does not have 'Information'.

  • HowTo/Set the recording folder. Tools -> Preferences -> Input&codecs and Record directory or filename.

GUI

On VLC 3.0.8 I am using in Ubuntu 18.04, the 'stream' option is gone in Open Network Stream... dialog. This option is not gone but it is hidden under the "play" button. The "play" button has a drop-down menu with 'Enqueue', 'Play', 'Stream', and 'Convert' options. We can choose the Convert option from there. I use this method to convert a m3u8 URL and save it as a mp4 file (the 'mp4' format can be confirmed by the Video DownloadHelper add-on). For a 19:41 minutes videos, it takes 216MB disk space for the 1280x720 29.97fps video.

The URL is obtained through the Video DownloadHelper v7.3.9 (3M users) add-on/extension on Firefox.

Command line

http://www.ubuntugeek.com/how-to-record-internet-radio-using-vlc.html 

sudo apt-get install vlc browser-plugin-vlc

sudo apt-get install ubuntu-restricted-extras

sudo apt-get install lame  libmp3lame0
sudo apt-get install ffmpeg
sudo apt-get install libavcodec-extra-53 libavdevice-extra-53 libavfilter-extra-2 libavformat-extra-53 \
                     libavutil-extra-51 libpostproc-extra-52 libswscale-extra-2

A successful run will have an output like 

VLC media player 2.0.3 Twoflower (revision 2.0.2-93-g77aa89e)
[0x2329ca8] dummy interface: using the dummy interface module...
[0x7fac2c007428] mux_dummy mux: Open

[0x7fac2c005fe8] idummy demux: command `quit'

Timer for recording

Automate VLC schedule recording. The following will run for about 30s & VLC will be closed after that. VLC media player 3.0.20 Vetinari (revision 3.0.20-0-g6f0d0ab126b) on Debian 11. This will open VLC without steaming on display. But the recording is fine. Change 'vlc' to 'cvlc' will lose audio in the recorded file. 

$ vlc http://localhost:9981/stream/channel/XXXX \
  --sout "#transcode{}:duplicate{dst=std{access=file,mux=ts,dst={vlc-record}}}" \
  --run-time=30 --stop-time=31 --play-and-exit

The file specifies that the output should be written to a file. The ps specify the file format in which the stream should be saved. In this case, it's set to PS (Program Stream), which is a container format commonly used for MPEG video streams. 

$ cvlc http://localhost:9981/stream/channel/XXXX \
  --sout=file/ps:output.mp4 \
  --run-time=30 --stop-time=31 --play-and-exit

Use the at command or creating a cron jobs for scheduled recording. Schedule a job to run at 21:05 Oct 21 2024. The date can be omitted. 

echo "cvlc http://localhost:9981/stream/channel/XXXX --sout=file/ps:output.mp4 --run-time=30 --stop-time=31 --play-and-exit" | at 21:05 102124

Audio device

I can specify to use a bluetooth device to output the audio in VLC while the browser still uses the regular 3.5mm as the output.
