Basically, if I view a webm file (produced by my webcam with cheese) in kdenlive and skip to the middle, the last few minutes will fast forward until the video catches up, rather than just skipping to the point in question.
This would be fine if it only happened in the preview window but it happens when rendering too. I fixed this once before as I have a kdenlive project where it skips to the correct part, but that was months ago and I forgot how I did it (Or just did it with luck somehow)
By looking at the .kdenlive xml files I can see the one that's working is set to "55 fps" in various places while the one that's not is set to "1000 fps" though don't ask me why.
Here are the lines from the file I think might be related to the problem.
