Fix Movit NVIDIA issues
Open, Needs TriagePublic

Description

Movit is not working correctly on NVIDIA cards.
We want to collect infos about this issue for fixing it.

I have a GeForce GTX 660 Ti, let me know what to do to test it.

As I read you make some works on the code for beginning to fix Movit issues I made 2 tests.
The first time Kdenlive crashes just because I loaded a gui layout. The second time because I imported a clip into the project window..

Hi, Afarid. :)
Just launch Kdenlive via terminal and copy what the prompt says.
I think that these informations could be useful for Jean-Baptiste.

PS: of course before to launch the application for testing it, remember to enable the gpu effects (Movit) in the Kdenlive settings. :)

I get this when running 16.04.1:

I will install latest git and eventually help test it.

I have three machines: one running two 980ti's, one running two 660's, and one laptop running two 970ti's (none of them SLI'd).

Let me know what I can do to help test this. Getting movit to run with Kdenlive for GPU processing would be absolutely incredible.

Hi Jessed.
Wat we can do for helping Jean-Baptiste is to run Kdenlive by the terminal and copy what the prompt says.
The informations about the crash in 3 differen configurations could be very useful.
Thanks in advance.

After the latest fixes this is my prompt:

Thanks, massimostella. Should I submit separate bugs, or simply copy the code (or backtrace data?) on this forum?

Actually, in my configuration, if the GPU effects are turned on you can't use Kdenlive because it immediately crashes.
For this reason, I copied everything happened in my terminal. It was a short sequence and I guess it contains all the infos (Graphic card version, Kdenlive errors, etc) which can help Jean Baptiste.
If your situation is different (for eg Kdenlive crashes only when you use a GPU effect but, for the rest, it's stable and you can use it) you can just turn it on, import a clip, put it on the timeline and add a GPU effect so we'll know what are the differences in your system behaviour; I guess that this could be very useful.
Thanks for the collaboration. :)

Though I can't still use the GPU effects on the Nvidia card I found some progress:
Now I can launch the program, load clips and put them on the timeline. Even if Kdenlive is not very stable when you use it with GPU effects turned on it mostly crashes only when you apply a gpu effects to a clip.

After I compiled the latest version the situation I found that the situation has improved a lot.
Now I can launch the application, I can load clips in the project, I can insert some of them in the timeline and I can apply GPU effects but I can't preview the timeline for setting the filter and if I try to do it or if I try to play the timeline Kdenlive crashes.
I tried all this by using the blur filter.

After I installed the MLT stable version (instead of the git one) I tried again to test Movit. Now, Kdenlive crashes when you want to palyback the timeline also if you didn't put any effect on any clip.

I encountered a Movit crash while using it in a test. Here's a link to the backtrace log (https://www.dropbox.com/s/otibuu6newtpebn/backtrace.log?dl=0). Should I submit these here or on the KDE Bugtracker?

Steps to reproduce:
(1) Open Kdenlive
(2) Open a recent project
(3) Select the Project Monitor widget.

Running on:
Kdenlive 16.11.70 git master build
Kubuntu 16.10 beta 2 x64
KDE Plasma 5.7.2
KDE Frameworks 5.26.0
Qt 5.6.1

Forgot to add using Nvidia 367.44 proprietary driver. Running two Nvidia GTX 970ti's in my laptop, though Kubuntu is only actually using one of them (unless programs like Blender specifically use both GPU's).

Here's another backtrace log from a similar encounter (https://www.dropbox.com/s/50c5eeb91p5w8ex/movit_backtrace_log2.txt?dl=0), except this was on a new project, I added a clip, marked my in and out zones, pressed V to insert the clip in the Timeline, THEN clicked the Project Monitor tab to open the Project Monitor widget. Kdenlive crashed, then.

@afarid , thanks buddy. Should I keep sending crashes I find to this task on the workboard, or should I post an individual bug on the KDE Bugtracker for each crash with a backtrace log? Whichever is JBM's preferred communications channel for these issues, I'm good with.

Here is a crash caused from attaching/detaching project/clip monitors.
