Unable to pan zoomed images

[m41t]

I am trying mvi on a QubesOS qube, running debian 11. mvi can open images, but once I zoom in, I cannot pan (move) the image. Ctrl + (arrow keys) are doing nothing. Alt + (arrow keys) are doing nothing. Mpv does NOT report "No key binding found for key 'Ctrl+right'" but still I cannot pan over the zoomed in image.

Here are the terminal outputs when I open a folder full of image files:

[user@dotfiles]:~/QubesIncoming/mmedia % mvi chiaroscuro
[file] This is a directory - adding to playlist.

Here's my mvi config directory:

[user@dotfiles]:~/.config/mvi % (U! master) tree
.
├── input.conf
├── mpv.conf
├── script-opts
│   ├── detect_image.conf
│   ├── image_positioning.conf

3 directories, 14 files

And here's the mvi alias:

[user@dotfiles]:~/.config/mvi % (U! master) alias mvi
mvi='mpv --config-dir=$HOME/.config/mvi'

Why am I unable to pan the zoomed images? Is this due to some limitation of QubesOS virtualization?

[occivink]

I doubt it's related to the virtualization. You can check whether mpv properly receives the shortcuts in the first place by doing mpv --no-config --input-test --idle --force-window, and then check if it reports Ctrl+left/right/up/down. If it does, then it's probably the case that your input.conf does not contain the proper bindings.

Here's what I get:

[input] Key MOUSE_MOVE is bound to:
[input] 1.  'script-binding osc/__keybinding1' in section {showhide} in <api>:1
[input] 2.  'script-binding osc/__keybinding3' in section {showhide_wc} in <api>:1
[input] Key Alt+RIGHT is bound to:
[input] 1.  'add video-pan-x -0.1' in <builtin>:1 (default)
[input] Key Alt+LEFT is bound to:
[input] 1.  'add video-pan-x  0.1' in <builtin>:1 (default)
[input] Key Alt+DOWN is bound to:
[input] 1.  'add video-pan-y -0.1' in <builtin>:1 (default)
[input] Key Alt+UP is bound to:
[input] 1.  'add video-pan-y  0.1' in <builtin>:1 (default)
[input] Key Ctrl+LEFT is bound to:
[input] 1.  'no-osd sub-seek -1' in <builtin>:1 (default)
[input] Key Ctrl+RIGHT is bound to:
[input] 1.  'no-osd sub-seek  1' in <builtin>:1 (default)
[input] Key Ctrl+UP is bound to:
[input] (nothing)
[input] Key Ctrl+DOWN is bound to:
[input] (nothing)

Ctrl/Alt + arrow-keys doesn't seem to be reporting to the mvi scripts, am I wrong?

If it does, then it's probably the case that your input.conf does not contain the proper bindings.

Am I supposed to edit the input.conf file and add the bindings? I assumed it would contain default bindings.

Am I supposed to edit the input.conf file and add the bindings? I assumed it would contain default bindings.

That's correct, it's mentioned here

[m41t]

The following lines came with the input.conf file:

ctrl+down  repeatable script-message pan-image y -0.1 yes yes
ctrl+up    repeatable script-message pan-image y +0.1 yes yes
ctrl+right repeatable script-message pan-image x -0.1 yes yes
ctrl+left  repeatable script-message pan-image x +0.1 yes yes

# now with more precision
alt+down   repeatable script-message pan-image y -0.01 yes yes
alt+up     repeatable script-message pan-image y +0.01 yes yes
alt+right  repeatable script-message pan-image x -0.01 yes yes
alt+left   repeatable script-message pan-image x +0.01 yes yes

Aren't they setting the alt/ctrl + cursor keys for panning the image already? If not, how should I change those? This is my first time setting up keybinds for mpv on input.conf, so I would appreciate an example.

[occivink]

and does the input.conf file in your config directory contain these lines? this is what matters. Please upload the .config/mvi/input.conf file

Here's my ~/.config/mvi/input.conf file:

# ADVANCED: you can define bindings that belong to a "section" (named "image-viewer" here) like so:
#alt+SPACE {image-viewer} repeatable playlist-prev
#SPACE     {image-viewer} repeatable playlist-next
# to load them conditionally with a command. See scripts-opts/image_viewer.conf for how you can do this
