kdenlive: DV module, QImage, Title module disabled

[hemant_verma2000@…]

Hi,

I recently installed kdenlive on OS X Yesomite 10.10.2. It installed successfully. However, DV module, QImage and Title modules are disabled in the config wizard and I believe, because of that I'm facing the following issues on the "Add title" window:

1. 'Ok' button is always disabled. Only 'Cancel' is enabled. So I can't add a title clip.
2. When I click on colour section, the colour palette doesn't appear.

melt: 0.9.2

Qt: 4.8.6

KDE Development Platform: 4.14.3

kde4-config: 1.0

Anyone else has faced similar issues?

Thanks

Do you mean with "Add title" window actually the "Title Clip" window (which can be reached through "Add title clip")?

In there at least I do see an enabled 'OK' button!

Well, but there is no colour selection, so I conclude that I am not checking at the correct place.

Please give more information how to reproduce what you've found.

(I have only very basic knowledge of kdenlive's workflows!)

I can confirm the original poster's experience:

In yosemite 10.10.2, I just installed, via MacPorts, Kdenlive version 0.9.10 using KDE Development Platform 4.14.3. (A year ago or so, I had installed and then uninstalled Kdenlive. I don't know if that might have any effect.) I followed the procedure described at ​https://kdenlive.org/download-mac.

When I launched Kdenlive, the config wizard appeared. Under Installed modules, it reports missing or disabled DV module (libdv), Image module, and Title module.

Project > Add Title Clip opens the Title Clip window, but the OK button is disabled, and I've not found any way to enable it.

OK, herewith I can verify that after a rebuild of the application on 10.9.5 I DO see the same symptoms. :(

I have no idea how to fix this and I suggest to contact upstream for further advice.

confirmed on a clean install of macports and kdenlive. The kdenlive board reports the issue being a broken (misconfigured) MLT build, missing QImage and kdenlivetitle modules. (see ​https://kdenlive.org/forum/adding-title-clip-ok-button-greyed-out-cant-add )

port install libdv and port install mlt both report all is well.

Replying to billy@…:

... missing QImage and kdenlivetitle modules. (see ​https://kdenlive.org/forum/adding-title-clip-ok-button-greyed-out-cant-add )

yes, indeed, those are missing!

Dan, do you have a clue what regarding MLT? Are you still maintaining this port?

[ddennedy (Dan Dennedy)]

Yes, I am still maintaining MLT port, but not kdenlive. The DV module is not required for Kdenlive even though it has a check for it; I don't know why. DV module is very rarely needed. While MLT does not have a hard dependency on Qt, it is pretty needed by Kdenlive. MLT portfile change r72609, removed the qt4-mac dependency and added the qt4 PortGroup. I think that adds the dependency in a different way. If that does not work anymore, then I do not know why. Is the problem that the dependency is not existing and qt4 not installing before mlt? It will take me a while to update macports on my system to test this against something current.

[ddennedy (Dan Dennedy)]

I see the problem. qt_libs_dir needs to be changed to qt_frameworks_dir, but I am having trouble getting port to read my local Portfile changes (after running portindex) in order to fully test this. I don't know why, and frankly I am getting tired of trying to figure out why.

[mkae (Marko Käning)]

Replying to dan@…:

qt_libs_dir needs to be changed to qt_frameworks_dir

OK, I will check that out and report back.

Thanks for caring, Dan! :-D

[ddennedy (Dan Dennedy)]

After giving up on my local ports Portfile, I edited the Portfile in the synced tree, but changing qt_libs_dir to qt_frameworks_dir did not work. Neither did removing --qimage-libdir and --qimage-includedir to rely upon pkg-config. Meanwhile, both approaches are working for me at the command line outside of MacPorts (cd ~/src/mlt; ./configure... against macports-installed dependencies). Still trying to figure this out.

[ddennedy (Dan Dennedy)]

Fix qt4-mac dependency

[ddennedy (Dan Dennedy)]

I solved this and attached a patch for the mlt Portfile. Not only is qt_frameworks_dir needed, but the name of the MLT module changed from qimage to qt in this version of MLT, which required changing the name of the configure args.

[ddennedy (Dan Dennedy)]

Also, the DV module in MLT is deprecated and no longer available as part of the normal MLT build process. Like I said, it is not needed if you have the avformat (ffmpeg) module.

[ddennedy (Dan Dennedy)]

Upgrade MLT to v0.9.6, fix qt module, drop libdv dependency, add libexif dependency.

[mkae (Marko Käning)]

Thanks, Dan, I've committed your mlt patch in #47513.
