[Request] Allow additional video formats to appear in the timelapse tab

[FormerLurker]

Is it possible to add support for the following formats within the timelapse file browser:
GIF
AVI
FLV
VOB
MPEG (might already work actually, need to test)

As you may have guessed, this is for Octolapse so that I can synchronize additional formats that are supported by the plugin. Currently I can copy the files into the timelapse folder, but they will not display and I cannot download them with a direct link.

Thanks!

Did the same happen when running OctoPrint in safe mode?

I added some formats a while ago, have a look at #2409 to see the work involved.

FWIW, 'vob' is currently the default format, but using the 'mpg' suffix.

I just added a new hook octoprint.timelapse.extensions that can be used to add additional supported extensions.

Available on maintenance, soon devel, to be released with 1.3.10.

@foosel, the hook worked as expected, excellent! 👍 This is a pretty big upgrade for Octolapse since the other video formats were too much of a bother to use before.

I did have to remove the _sendingLock from the _handle_ok method to test it out, but I was expecting that. Now to remove all of the warnings about which formats will sync from my settings and help files.

1.3.10 has been released.
