Try to determine the default video play using xdg-mime

[adamreichold]

Use xdg-mime to query default application for MIME type video/mp4 and then try to grep binary path from desktop file's Exec entry.

f19aeca still shows vlc for me, even if I rm -rf .local/share/QMediathekView/ before launching.

me@host:~$ vlc

Command 'vlc' not found, but can be installed with:

sudo apt install vlc-bin

f19aeca still shows vlc for me, even if I rm -rf .local/share/QMediathekView/ before launching.

Can you tell me what

sh -c "grep '^Exec=' /usr/share/applications/`xdg-mime query default video/mp4` | cut -d'=' -f2 | cut -d' ' -f1"

yields on your system?

Ah, do not that the configuration probably lives in ~/.config/QMediathekView. But you can just try the "Restore defaults" button in the settings dialog as well.

@probonopd I know this is not strictly related, but is there an easy way to trigger an update of the meta-data (screenshot, AppStream meta-data) on AppImageHub?

Define "easy"... editing https://github.com/AppImage/appimage.github.io/blob/master/data/QMediathekView will trigger a new run of the test. (I should probably code something so that application authors can press a button to trigger new runs.)

All of the actual data gets into the database in a fully automatic way, you can see the history here: https://github.com/AppImage/appimage.github.io/commits/master/apps/QMediathekView.md

I thought of that, but I am not sure what to edit there? Adding a newline just to trigger this?

Currently yes, I know it's not ideal yet.

[adamreichold]

So does it work using the "Restore defaults" button? What does that grep line yield?

[probonopd]

In f19aeca the button is too small to read the text, clicking it does not seem to do anything. Also no output in the terminal.

[adamreichold]

Also no output in the terminal.

That is expected, but what does running

sh -c "grep '^Exec=' /usr/share/applications/`xdg-mime query default video/mp4` | cut -d'=' -f2 | cut -d' ' -f1"

in a terminal yield for you?

[probonopd]

I have to admit that this is interesting, to say the least...

me@host:~$ sh -c "grep '^Exec=' /usr/share/applications/`xdg-mime query default video/mp4` | cut -d'=' -f2 | cut -d' ' -f1"
grep: /usr/share/applications/parole.desktop: No such file or directory

me@host:~$ find /usr/ | grep parole | grep desktop
/usr/share/parole/parole-plugins-0/mpris2.desktop
/usr/share/parole/parole-plugins-0/notify.desktop
/usr/share/parole/parole-plugins-0/system-tray.desktop

Maybe there is a better way to find out the default video player...

[adamreichold]

Maybe there is a better way to find out the default video player...

But how does that work, i.e. xdg-mime yields parole.desktop but that file does not exist on your machine even though Parole is installed? Does it use some other launcher file? In any case, I am happy for suggestions on to do this...

[probonopd]

Have to admit that I am puzzled here, too

Ok, so I guess you do have Parole installed? And when you apply xdg-open to an MP4 file, it will run Parole? If so the question is just how your DE infers the correct desktop file from the ID given by xdg-mime? Do you know which desktop file Parole is started from?

[probonopd]

There are more locations in which desktop files can reside, e.g., .local/share/applications/. Sorry if I mislead you with the xdg-mime command, I think that's a partial solution at best and we (I) don't know the "proper" solution yet.
