Description gudvinr+kde 2025-06-28 16:42:30 UTC

SUMMARY

When I run recording, it produces files with no extensions.
Turns out, default recording format is nothing (i.e. combobox with empty string).

Recording isn't failing and screencap is webm.
Thus, combobox default should just match default format.

STEPS TO REPRODUCE
1. Start spectacle
2. Start recording

OBSERVED RESULT
Recordings do not have any extension

EXPECTED RESULT
Recordings have extension of default format

Do you see this if you click the "Defaults" button in the config window? What about if you remove ~/.config/spectaclerc and restart spectacle?

Comment 3 John Veness 2025-08-18 20:11:32 UTC

For me, doing either of those things (pressing Defaults in the config window, or removing spectaclerc) fixes the problem. My spectaclerc before doing that (i.e. from older versions of Plasma), which demonstrates the no extension problem was:

[Annotations]
ellipseStrokeColor=255,0,0

[General]
launchAction=DoNotTakeScreenshot

[GuiConfig]
captureMode=0
includeShadow=false

[ImageSave]
lastImageSaveAsLocation=file:///home/john/Pictures/Screenshots/Discover accessibility icon.png
lastImageSaveLocation=file:///home/john/Pictures/Screenshots/Discover accessibility icon.png
translatedScreenshotsFolder=Screenshots

[VideoSave]
preferredVideoFormat=0
translatedScreencastsFolder=Screencasts

In my config file, I have "videoContainerFormat=mp4" under the "[GuiConfig]" group.

For testing purposes, if you add that to your config file and re-open Spectacle, does that fix the issue?

Comment 5 John Veness 2025-08-20 20:25:05 UTC

Nope, that makes no difference.

I noticed that if I delete the preferredVideoFormat=0 line it works OK (puts a .webm extension on the filename).

Nope and nope. 

> preferredVideoFormat=0

Same for me. I am pretty sure what happens is someone at some point added check like "if (param == "") || (param == nullptr) { format = defaultFormat; }" and then there's something like "switch format { case webm:; case mp4:; case default:; }" and 0 isn't handled by anything.

BUT someone at some point also added writing "default" option to config file on save and default option for format was zero value of integer (which is 0) instead of "nothing".
