Segmentation Fault

Let's start with the basics. What OS (name and version) are you using? Is it a 32 or 64 CPU? And lastly, were you able to run any of the MLT demos? Try this and let me know what happens:

$ cd ~/mlt/demo
$ sudo bash mlt_watermark

Does a new window open up? Does it have a giant "Ok" icon in the window? Do you get an error?

If the demo doesn't work then that would indicate MLT is not installed correctly. I would re-run the OpenShot build wizard, and pay close attention to any build errors. They are not very obvious sometimes.

Thanks,

Wow you're quick to answer.

Sorry, I have Ubunut 9.04.
I didn't noticed any error during the wizard but I'll pass trough the history to see again.

Ok mlt runs and display the big "ok" icons however it tells me that it fail to load a certain clip, i give the messages on the console:

Failed to load "clip2.dv"

OK this might help:

I reruned the install.py and I noticed this message:

"avformat: No build environment found."

Thank you.

Please try this command, and post the output:

$ melt -query producers

Also, just out of curiosity, can you post the output of these 2 commands:

Command 1:
$ ls /usr/lib/libmlt*

Command 2:
$ cd ~/mlt/
$ find . -name "libmlt*" -print

Hello,

Hare are the output of the three commands:

$melt -query producers

One last thing, it seems that the packages libavformat-dev in my repository is broken and so shouldn't be installed. I'll look into this. Do you think this might be it?

Thank you,
B.
