i have libsdl and libsdl_image from macports:

   libsdl @1.2.13_2 (active)

  libsdl_image @1.2.6_3 (active)

i use

  libsdl @1.2.13_5

and this worked from the begin with mlt and kdenlive, but i think 1.2.13_2 should work also ?

 but you have an ppc ? (i have it installed on intel-mac)

 Yes i have an ppc mac! I think this is the biggest problem in my case! 

FYI, MLT changed a lot recently. So, when you try again, please save yourself some time and use this Portfile already well under way and adapted to these changes:

http://trac.macports.org/ticket/18286

Alas, I do not know exactly the problem, but I do believe there will be a problem with embedded the SDL-based video window inside the Qt one on OS X.

Congratulations.
These are great news.

I don't have access to a Mac any longer.
Would someone here be interested in becoming MacPorts maintainer for these two packages?
Could you get in touch with MacPorts and commit these MLT and Kdenlive port files?

By the way, mkisofs is part of cdrtools.
qdvdauthor is part of MacPorts.

Maybe you could add them to dependencies to ease installation.

You can use:

depends_run cdrtool \
qdvdauthor

Bye and congrats!

Here is the MacPorts status :
* MLT was posted by Dan here: http://trac.macports.org/ticket/18286
* Kdenlive: https://trac.macports.org/ticket/19897

I hope that the build dependencies are enough. I had no building environment to verify. I removed the ffmpeg dependency in Kdenlive as it is included in MLT.

I contacted the MacPorts developers on the ML. Do not hesitate to test these two packages and propose enhancements on MacPorts trac.

Great news: MLT and Kdenlive is now part of MacPorts.

Looking at the screenshot, it seems that the monitor is broken. Is this for lack of proper GLX support in Mac OS X? Dan, what do your think of that? Do you have the same problem under MacOsX?

I finally have video embedded using a new MLT SDL audio-only consumer and a custom QGLWidget for video. It is still rather rough, but getting close!

More good news...
Nearly all of the known rough spots have been resolved - at least enough to let others start using it. Now, I just need to do a little cleanup, port the changes to the latest version of the code, and commit it. We should be able to have an officially working version for the next releases of MLT and Kdenlive!

I have committed the changes to MLT and Kdenlive to make the first real usable version for OS X! It does require OpenGL, and at this time I only expect it to work on Intel architecture machines.

I installed kdenlive from macports few weeks ago from a clean install of macports without problems.

Using the macports feature for building a pkg installer (port mpkg kdenlive) I built a package which one can install without macports. (Using macports is fine but you need more than 2 days, at least on my PowerBook G4 for compilation of the dependencies). I think it would attract much more users if there is a simpler way of installation.

Using this package one can install kdenlive within some minutes. Is anyone interested in such packages or is the way it works with macports fine?

I would not describe the way to build kdenlive with all dependencies bottom-up from source to be fine considering all of the pitfalls. Something changed on my OS X, and it is all screwed up now with architecture during linkage affecting my ability to build newer versions of MLT or kdenlive. I am going to have to completely uninstall and reinstall my ports, which is going to suck. So, if you feel comfortable distributing binaries, feel free to. Just be very clear it is for PPC. I did not know about mpkg - interesting way to let me share this with friends once I get it working again.

I am also new to using this feature of macports (mpkg). And my experience is that it is not always working as expected. However if one does not change the global variants in ${prefix}/etc/macports/variants.conf it seems to work.

As I have no access to different macs I could only test the package on my machine, and I also don't know if the package would work on different OSX versions.

If there are PPC packages of kdenlive, I could test them with my powermac g5...
