Web interface stream manager mosaic dialog is non-functional
As far as I can tell, the dialog does nothing when you click on "Create", and never did anything; and it also fails on a nonexistent get_dir()
call when trying to browse inputs, whose I couldn't find any trace. Apparently it was committed in that state when the current web front end was introduced in https://git.videolan.org/?p=vlc.git;a=commitdiff;h=3c2992fceed8e4780735c757bd5c43b9e3546193 9 years ago and was never changed. The previous version had an apparently functional mosaic feature, but it was removed after the non-functional was added: https://git.videolan.org/?p=vlc.git;a=commitdiff;h=e28b130295c4047c2b2a1ac0d1c33b02c2a6042d
This dialog is linked from a button in the stream manager, right next to the one to create normal streams. Obviously we shouldn't have a pretend non-functional dialog advertised from the interface. I guess we should either remove it or actually implement the feature.
