Kdenlive, mlt, ffmpeg, libx264 & libvpx are build from sources on latest 32-bit Kubuntu and Xubuntu.
Clips are played on timeline ignoring in and out point. Playback starts from the point where it stops before.
Also when I start command melt aaa.xml with content
I see the whole clip directly from beginning to the end.
FFmpeg correctly cuts video with flags -ss and -t. Tryed video clips in format mkv, avi, mpg and codecs mpeg1video, mpeg2video. No change.
Tryed clean system and install packages with Synaptic. No change.
