    Can't open multimedia apps

    Hello,

    I have upgraded to Mantic and have noticed that for a while, am unable to open multimedia apps - VLC, videos, rhythmbox, Deepin movie, QM2 play, Audacity... the app doesn't open.

    Or, if I try to open the file via Files, and try to select the app to open the audio or video from, I get the same result, the furthest I get is the app opening, but then immediately closing, without playing the file.

    I tried removing
    ffmepg
    and
    ubuntu-restricted-extras
    and then reinstalling them both, but I get no joy. I have both now as the most recent version.

    Incidentally, I can't open
    Code:
    Telegram-desktop
    either.

    I remember having issues with video files in the past, but never with audio files.

    I would certainly post outputs but don't know where to begin with. Any ideas anyone?

    First step should be opening the program from the command line. If you do that, the program has a place to send any warnings and errors (the terminal window). If you start programs from some kind of graphical starter these messages either get discarded or end up in a log file (probably ~/.xsession-errors if using X11 or something else for Wayland ...).

    I assume that you have tried rebooting the machine? Occasionally, I'll see something on the 'net and afterwards some programs are inop. Won't happen for weeks or months, but then a couple times in just a few days. Rebooting makes everything work again.

    Re: Can't open multimedia apps

    I think I wanted to switch to flatpack instead of snap for some other app.
    When I tried vlc help from terminal, I get:

    j-jdesktop:~$ vlc ~/Downloads/IMG_0037.mp4
    Command 'vlc' not found, but can be installed with:
    sudo snap install vlc # version 3.0.19, or
    sudo apt install vlc-bin # version 3.0.18-4
    See 'snap info vlc' for additional versions.
    And I'm playing an audio podcast at this very moment on VLC. But it still doesn't play videos.

    Re: Can't open multimedia apps

    If it is a flatpak, run this then:
    Code:
    flatpak run org.videolan.VLC
    That might help give us some clues.

You would be surprised at some dumb things that I have "fixed" for others by either having them reboot the machine or remove the laptop battery for a few minutes. Sorry that my reply seemed stupid to you.

    Re: Can't open multimedia apps

    I ran the command and got this:
    Code:
    flatpak run org.videolan.VLC
    === Begin org.videolan.VLC.Plugin.pause_click Usage Instructions ===
    You have installed org.videolan.VLC.Plugin.pause_click.
    This plugin must be enabled in order for it to work.
    
    (Recommended) You can enable it by using the following steps after the VLC launches:
      1. Tick "Pause/Play video on mouse click" checkbox in Tools -> Preferences -> Show settings -> All -> Interface -> Control Interfaces. Screenshot: https://i.imgur.com/m9yF5Px.png
      2. Tick "Pause/Play video on mouse click" checkbox in Tools -> Preferences -> Show settings -> All -> Video -> Filters. Screenshot: https://i.imgur.com/OZLqmI6.png
      3. Restart VLC
    Note that both checkboxes need to be ticked for the plugin to function!
    
    (Alternative) You can pass:
      --control=pause_click --video-filter=pause_click
    arguments when running VLC to enable the plugin.
    This method enables the plugin only for this specific VLC run, i.e. it's not persistent.
    
    Plugin settings are available under Tools -> Preferences -> Show settings -> All -> Video -> Filters -> Pause click. Screenshot: https://i.imgur.com/Kdrekks.png . The settings changes apply right away, there is no need to restart VLC.

    I installed canberra-gtk via Synaptic (I still had canberra3 installed) and then ran the command to open VLC. I still get the message that canberra has not loaded up.

    Re: Can't open multimedia apps

    That message is totally harmless " canberra-gtk".
    We are running it through the terminal so "Warnings or Errors" is not uncommon.
    Now will you do the same again, but open a Video file or URL and post that back here please.

    If I try to open a video file from GUI, I can hear some audio for about 1 sec, and then VLC shuts. But this output is from terminal.
