[Bug 827951] Re: Openshot cannot find already installed codecs
In the current development trunk we have removed the use of melt to get
the codecs, we now directly use a MLT api. This may well fix your issue,
but it's difficult to tell.

Title:
Openshot cannot find already installed codecs
Status in OpenShot Video Editor:
New
Bug description:
Os name & version: 2 different machines:
Debian wheezy kernel 3.0.0-1-powerpc64.
Debian wheezy kernel 3.0.0-1-i386
Installation method: DEB packages
Openshot version: OpenShot 1.3.1
Bug info:
Everytime I launch openshot, a little window shows the message:
"No formats or codecs were found. Please check the OpenShot preferences and configure the 'melt' command name."
Everything related to melt and openshot preferences is already configured, all codecs are installed as well. As a matter of fact, openshot starts correctly and is also possible to edit videos, but exporting them is not possible.
IMHO is all related to a malfunction of melt program which segfaults every now and then. I attach the openshot.debug file, and also a gdb-debugged sesion of melt:
