Bug Description

This is a problem in the current development version (1.0.5) *not* 1.0

System: Fedora 12 x86_64

When trying to export video I get no codecs at all in the drop down lists

This is because openshot is trying to run a command such as

    melt noise -consumer avformat vcodec=list

to get the list

However I have the rpmfusion version of mlt 4.10 which installs the command-line utility as mlt-melt consequently the above command fails.

As an aside I get no indication that there was any error listing the codecs

Good catch. Sounds like the name of the melt command should be configurable, and probably a bit of error handling needs to be added. Or... maybe if 'melt' is not found, it just defaults to all codecs. Just an idea.

Changed in openshot:
milestone: none → 1.1.0
importance: Undecided → High

I'd be inclined to add it as a preference along with some indication that things had failed.

An alternative would be to check for melt vs mlt-melt as Fedora users are likely to have the latter but then you get into the thorny issue of searching $PATH, and someone somewhere will still complain that they have some other setup that gives the executable a different name.

Is there a way to get this from the mlt library rather than running the command? - I nearly labelled this as a security bug on the grounds that *anything* which runs a sub-process via a shell is a security bug :-)

The "melt" command is not configured to use the ./openshot/config.xml file. A warning message is now shown if no formats/codecs are detected. The OpenShot preferences now contains a "melt command" textbox, which allows the user to update the command.
