GSoC2013: Progress

The video test producer's caps could not be parsed because of the formatting. I fixed that with correct placement of commas -> [7c12ca0]

Other changes -> [5a1ac72]

File "/home/max/Desktop/flumotion-porting/flumotion/flumotion/common/gstreamer.py", line 51, in verbose_deep_notify_cb
value = orig.get_property(pspec.name)
AttributeError: 'NoneType' object has no attribute 'name'

Printing the arguments in verbose_deep_notify_cb in gstreamer.py gives the following:

'print object' prints <Pipeline object at 0x9cb0c34 (GstPipeline at 0x9ce6c38)>

'print orig' prints <__main__.GstMultiFdSink object at 0x9868c0c (GstMultiFdSink at 0x98656d0)>

'print pspec' prints None

'print component' prints all components in the pipeline

Printing pspec in the pre-ported Flumotion shows that it's only a log of the pipeline properties/specifications.

Tried a lot of things, but at the end i did this to get pass the problem:

This change needs to be applied here: https://github.com/bananadine/flumotion/commit/5a1ac72140408aeb84be09cc99de792c01390fcd#L1L1019

Instead of calling the method on Gst.Element (which makes no sense) I need to call it on something which is a GstElement.

I'll post the current worker output tomorrow/later in an edit to show what needs to be fixed.
