[Kdenlive-devel] Setting the paths for MLT?

[Mads B. D. <ma...@dy...>]

Hi there

I have multiple installs of mlt and kdenlive on my system. When running 
kdenlive, it will read the configuration information about which MLT to use, 
both profiles, and the path to inigo.

Is there a way to override this? During install? As a command line parameter?

I ask, because I would like to embed this into my Kdenlive Builder Wizard, so 
people get to use the version of MLT that they have just compiled... :-)

If there is no way, I would not mind trying to provide a patch to read it from 
the command line or whatever would be best?

Regards

Mads

Currently there is no way to override it. If you delete the config file ( 
$HOME/.kde/share/config/kdenliverc ), Kdenlive will try to detect MLT using 
the MLT_PREFIX variable that is defined at install time (by the cmake module 
FindLIBMLT.cmake ).

So basically removing the config file (or deleting the necessary lines) should 
make Kdenlive use the MLT version used for its compilation.

I also just commited a change so that the renderer (kdenlive_render) is now 
taken from the same folder as the running kdenlive instance.

If you still want to work on a patch, it's ok for me.

regards

Hi jb.

Would you please consider this very small patch:
$ svn diff mainwindow.cpp
Index: mainwindow.cpp
===================================================================
--- mainwindow.cpp      (revision 2442)
+++ mainwindow.cpp      (working copy)
@@ -982,6 +982,13 @@

 void MainWindow::parseProfiles() {
     //kdDebug()<<" + + YOUR MLT INSTALL WAS FOUND IN: "<< MLT_PREFIX <<endl;
+    // If MLT_PREFIX is specified in the environment, it overrides the stored
+    // setting.
+    QString mltPrefix = getenv( "MLT_PREFIX" );
+    if ( mltPrefix != "" ) {
+      KdenliveSettings::setMltpath( mltPrefix + "/share/mlt/profiles/" );
+      KdenliveSettings::setRendererpath( mltPrefix + "/bin/inigo" );
+    }

     //KdenliveSettings::setDefaulttmpfolder();
     if (KdenliveSettings::mltpath().isEmpty()) {

AFAICT this works, and allows me to set MLT_PREFIX in the environment, and 
have kdenlive use it.

The drawback is that kdenlive stores this in its settings, but if it is only 
used from the wizard, not very many users should have problems with this.

Please let me know if you can accept it, as I need to update the wizard to use 
this. Most installs done by the wizard, using the append date options is 
broken, and I would really like to fix that :-)

Thanks

Mads
