KDEnlive displays wrong frames

Tue Jul 25, 2017 11:25 pm
I have a GIF animation with custom time delays set to each frame to control how long each of these frames displays.
KDEnlive doesn't seem to support animated GIFs directly, so I converted it with ffmpeg to a MKV video file.
The file plays fine in mplayer.
But when I import it as a clip to KDEnlive, it displays incorrect frames!
E.g. when frame 1 is supposed to display for 2000 ms, and then a sequence of frames from 2 to 10 is supposed to display for 100 ms each, KDEnlive skips immediately to the frame number 2 and displays it for 2000 ms instead :P
This happens no matter what video format I use for my output from ffmpeg.
And it still displays wrong after I render the final video.
All these formats play just fine in mplayer, no prematurely skipped frames, no timing issues, everyghing is OK.
The problem exists only in KDEnlive (version 0.9.8 under Gentoo Linux).
Am I doing something wrong? Is this some misconfiguration or a bug?

Edit: I just checked it with KDEnlive 15.08.1 on Ubuntu – same problem.
The problematic movie clip can be downloaded from here: http://sasq.comyr.com/Stuff/Mnozenie_anim.mkv (60 KB)
