View Full Version : [SOLVED] Arista Transcoder Fedora 15

15th July 2011, 01:56 PM
Hi Folks,

New to the forums, long time linux nerd but haven't touched Fedora in years. Recently back to Fedora from a "stint" with Ubuntu and I am having a bit of an issue.

Anyone get Arista Transcoder to work with Fed15? Seems like a Gnome issue to me, basically the UI loads but when I try to create a job I get nothing, click the button and nada.

Any help would be great, even if it's "Does not work in Gnome Shell" just need confirmation.

I've followed the instructions here and they work for me:

Generally I'll have all the gstreamer plugins installed plus ffmpeg and mplayer/encoder... I believe something like this will do all that:

yum install gstreamer-plugins-good gstreamer-plugins-bad gstreamer-plugins-bad-free gstreamer-plugins-ugly gstreamer-ffmpeg ffmpeg mplayer mencoder mplayer-gui gecko-mediaplayer

I use these when setting up a machine for the first time:

So yep, using the instructions from the first link above, Arista works. Just converted a flash video to webm...

Good luck! :D

Thanks for the response, but no-go.

It is quite bizarre, not a codec problem as I can run the cli version without issue. Simply this, open the GUI, click "Create Conversion" and nada... Nothing... Zip.

No dialog opens at that point so I am assuming this is a GTK/Python issue.

How strange... I've installed it on a 64-bit and 32-bit machine with no problems...

I tried /usr/bin/arista-gtk from the terminal, does not give a lot of output, just:

** Message: pygobject_register_sinkfunc is deprecated (GstObject)

Also tried running it through pydb (python debugger) but that was no help either.
Using lsof, determined that no additional files seem to be opened when the dialogue box for Create Conversion is opened...

I'll assume you downloaded the arista-0.9.7.tar.gz archive rather than from trunk (which is what I did - use the archive that is).

Perhaps there's a dependency missing?
I've run yum list py* and attached the output as text...

It's a long shot but you could compare against what you have installed and see if anything jumps out at you?

Thanks for working with me on this.

Yes, downloaded 0.9.7 as apposed to getting it from git.

When I launch arista-gtk from cli I get the same "pygobject" message, but when I click the create conversion I get this:

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files

A bit of googling and this does not seem to be correct, according to the release notes Arista should not be depending on the Hal?

Interesting... what packages do you have installed when you do yum list *hal*?

Please can you try this:

yum install hal-filesystem hal-info hal-libs hal-storage-addon

...and try again?

Please can you try this:

yum install hal-filesystem hal-info hal-libs hal-storage-addon

...and try again?

That did it!

Thanks a bunch. Going to take me a while to get used to Fedora again but I am committed to it.

I owe you a beer.

Funny how these things happen, I was trying to install Arista in Fedora 16 and had the same problem you had - of course, HAL has been removed in F16. So, I found the answer here:

"If you have python-gudev installed it will use udev rather than dbus/HAL for device discovery. HAL support is left in for older distros that don't have udev yet!"

So, to fix, we do the following as root:

yum install python-gudev

...then it works!

This also works for me on Fedora 16, thanks! Just installed python-gudev and now it works. Cheers!

I tried that with mine in terminal and it didn't work
