gstreamer error

1
Sorry to be a bother, but I cannot find a solution to my problem online yet so I thought I would post.

I cannot play videos (including SimpleMovieDemo) with psychtoolbox because I get this gstreamer error pasted below. I have a macbook pro, am running mountain lion, and matlab 7.9.0 r2009b. I just updated psychtoolbox, downloaded xcode (and installed the command line tools), and downloaded all of gstreamer today so everything should be up to date.

Have you considered at some point reading the installation instructions, as pointed out by ptb to you? Citing from what you posted:

At some point we'll switch to the version 1 series, but given that v1.x is less than a year old, whereas the 0.10 series had a decade to mature, my feeling is to take things slowly, given the complexity of the software.

That's depressing. Apple calls this loss of default functionality in 10.8 progress? I hope there are some places one can download Subversion for OSX with some lower overhead than a full XCode download?

You can just download Command Line Tools for Mountain Lion from Developer Downloads (~120 MB).

I did read the instructions and understand that 1.0 series isnt yet supported. The PTB gstreamer help gives a link for download and this leads you to the 1.0 series not the .10 series. This is probably because gstreamer stopped supporting the .10 series and changed their website after PTB put that link the help.

I posted here because I cannot find the correct version of gstreamer for download anywhere so I am looking for a workaround. Any advice would be appreciated.

So my whole lab seems to be stumped here. I downloaded/installed the runtime files from gstreamer.com as advised which initially appeared to work as Library/Frameworks/Gstreamer.Frameworks/ is now populated. Despite this, it seems like the install was not entirely successful because gst-launch-0.1 is an unrecognized command. There seems to be very little opportunity for user error in this install process - any thoughts on what could have gone wrong?

Also when I run SimpleMovieDemo still gives me an error. This time it appears to be looking for a plugin I dont have (error below). Any advice about where I can find this (and why this toolbox was missing in the first place)? Thanks so much.
