Doesn't it? With the post-plugin configuration windows, the individual options are there, the help text is there (though it's not necessarily all that helpful - that's down to the plugin), and if you want the actual string, it's in gui.post_plugins.deinterlace. > I call it an option, but there really is no option.

That should be possible. Something for 0.5.11, or maybe 0.6.0... -- | Darren Salt | linux or ds at | nr.

I found the windows you meant in the end, I didn't realise they were accessed in a completely different way from the other preferences. I set it to Greedy2Frame, but although it's saved the setting in ..gxine/config: gui.post_plugins.video:tvtime:method=Greedy2Frame [...] if I reload gxine it says LinearBlend again, even though the file still says Greedy2Frame. Perhaps I should paste the string from the above option into the box I found in the main preferences? And is gui.post_plugins.deinterlace a synonym for gui.post_plugins.video? The option was saved as gui.post_plugins.video but I used the deinterlacing plugin configuration window, not the general postprocessing one. -- The address in the Reply-To is genuine and should not be edited.

Hmm. Would duplicating them in File->Configure help...? > I set it to Greedy2Frame, but although it's saved the setting in > .gxine/config: > gui.post_plugins.video:tvtime:method=Greedy2Frame [...] > if I reload gxine it says LinearBlend again, even though the file still > says Greedy2Frame. Odd. Works for me. > Perhaps I should paste the string from the above option into the box I > found in the main preferences? No need - that is updated when you change settings via the deinterlacer configuration window, but updating that string manually isn't reflected in the deinterlacer window and any associated plugin windows (but clicking on Undo in the deinterlacer window will use the modified string). > And is gui.post_plugins.deinterlace a synonym for gui.post_plugins.video?

Would duplicating them in File->Configure help...? They have an effect there (the settings get entered into the deinterlacing/postprocessing string options) so it might help understanding if the windows to edit the options via the GUI were also accessible from there. >> I set it to Greedy2Frame, but although it's saved the setting in >> .gxine/config: > >> gui.post_plugins.video:tvtime:method=Greedy2Frame [...] > >> if I reload gxine it says LinearBlend again, even though the file still >> says Greedy2Frame. > > Odd.

Both of these are working for me now. I think the problem was that I ended up with the tvtime plugin enabled both in the deinterlacing and postprocessing settings, one I updated to Greedy2Frame, the other still on LinearBlend. This seemed to confuse gxine as much as gxine had confused me. >> And is gui.post_plugins.deinterlace a synonym for gui.post_plugins.video? > > No. I think there's a case for merging them. The only thing I can see that separates deinterlacers from other postprocessing filters (except that it's probably a good idea to always deinterlace before anything else) is the need for deinterlacing to be turned on and off. As such they just need a flag to identify them as a specialised form of pp filter. Trying to treat them as a separate type of plugin when they're all also available as general pp filters seems to do no more than add potential for trouble and confusion. -- The address in the Reply-To is genuine and should not be edited.
