Integrating GES in Pitivi : Weekly report 02 : Lots of troubles with track objects :/

[Mathieu Duponchelle <mduponchelle1 gmail com>]

Hi !

I've spent my week refactoring my formatter, and after successfully 
integrating the effects handling, I've banged my head against the track 
objects wall.

My first version worked fine, but I had worked around the following 
problem in a way that was not the ideal one :

When you create a timeline object, the track objects are not immediately 
created, and when timeline objects are ungrouped in Pitivi, you want to 
access the track objects of the timeline file sources to move them 
accordingly. I worked that around by creating two file sources when 
needed, and setting one mute and the other blind.

My new version added a "track-object-added" signal to GESTimelineObject, 
which I caught to move the track objects accordingly. This worked fine, 
but there is now another trouble : transitions added after track objects 
were created are not taken into account, even if GST_DEBUG tells me they 
were really added. I have a good test case that shows that, and I pushed 
that yesterday for bilboed and thiblahute to have a look.

I just started to have a look at the unhandled argtypes in the bindings, 
and I will work this week-end to get back in my schedule.

I'll be able to use the old version of the formatter to start 
integrating it anyway, for the API will not change when the refactoring 
is done.

By the next report, I plan to have finished the bindings, to have them 
merged soon, cause other GSoCers will need them. I will then start the 
integration, to reach the goal of my mid-term evaluation : having pitivi 
load projects, and see them in the viewer.

Have a good week-end :)
