Kdenlive is absolutely awesome - thank you!

I am running Kdenlive 16.12.2 on Kubuntu 16.04.

My graphics card is a NVIDIA Quadro K260 running the NVIDIA closed source driver 367.57. I have 2 monitors in a big desktop format.

I would like to use the graphic card's GPU to perform some of the effect processing, mostly Pan and Zoom and basic colour grading - Lift/gamma/gain (levels and curves would be great!).

Almost as soon as I apply any GPU effect I get a crash - usually Signal: Aborted(6). Mostly these look like exceptions being thrown in / by libmovit, possibly libmltopengl.

I can install the debug versions of these files if that is of help, or are these problems known about already?

Movit is still in an alpha state and therfor buggy, here are some known issues:

Triaging and submitting well documented bugs is always welcomed.

Thank you for the link to the bug tracker.

I have installed KDevelop and am able to build and run the GitHub version of the software in debug mode.

What I have noticed is that with a simple, single clip timeline and no non-GPU effects applied it seems quite stable. But if I open a more complex (existing) project just moving the cursor over the preview window causes a crash (which seems to be in a windowing dtor).

I don't think that I am at the stage of really doing any serious debugging because obviously kdenlive is a very complex multi-threaded piece of software. However, hopefully by trapping the exceptions in a debug environment I should be able to provide something a little meaningful.

I will post back as soon as I have some more.

Great, thanks!
