Hi,
I've already used it before, but now Kdenlive crashes whenever I try to import a clip into the project.
This is the error log: http://pastebin.ubuntu.com/559923/

~$ kdenlive -v
Qt: 4.5.2
KDE: 4.3.2 (KDE 4.3.2)
Kdenlive: 0.7.8


Is there something I can do to solve the problem?

TIA

Best regards,
MarcoA

I found that the crash occurs when I try to import an mp4 (H.264/AVC) video made using a Samsung camcorder (SMX-F30BP).
I also used the how-to in http://ubuntuforums.org/showpost.php?p=9114176&postcount=967 to update ffmpeg and x264 on Ubuntu 9.10, and kdenlive (and dependencies) from https://launchpad.net/~sunab/+archive/kdenlive-svn (0.7.8+svn20110129.r5358-0ubuntu0~sunab~karmic1), but the issue is still present.
I suspect the culprit to be melt, as i get the following error:

$ melt file.mp4
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x18152e0]ISO: File Type Major Brand: avc1
Segmentation fault

Is it true?
Is there something I can be to solve this without converting all files to something edible by kdenlive?

Thanks!

Best regards,

Does ffplay at the command line play these files? If so, then please file a bug in kdenlive (or mlt) and provide a small sample for debugging. If ffplay can not play them, then you should report it to ffmpeg project with a small sample.
Thanks
