Thibault Saunier 8dfac3c94f ges: Add debug output when get_element returns NULL 2015-04-20 17:42:44 +02:00
Mathieu Duponchelle 2e26a9e926 timeline, track: Emit commited at the correct moment.
Summary:
+ [API] GESTrack::commited signal.
+ [API] ges_track_commit_sync

We were emitting commited when timeline_commit was called, which
wasn't very helpful. This commit makes it so we emit commited once
all the compositions have actually been commited.

We also add a synchronous commit method to spare the user
the need to connect to the signal and wait, and update the
documentation.

Thibault Saunier f470222f3d Revert "ges: Move the notion of children properties to GESTimelineElement"
I got some trouble with

  arc land

and I wanted to push the 3 commit coming after this revert as 3
different commits but they ended up being all squash into one single
commit, which is clearly not cool for later bisecting and blaming.
Reverting that commit and re pushing those 3 commits as they were
supposed to be.

This reverts commit 9fe15ef435.

  should not be.

* Rename GESBaseXmlContainer->clips field to

Thibault Saunier f6038e3ad2 ges: Port to the new commit based API in GNL
The GNL API changed to go from a model where user could
enable/disable updates in the composition, which leaded to races
in many places, to a model where any positioning change in the
composition is not directly done but 'cached' and then the user
has to commit those changes so they become effective in the media
processing stack.

The new API in GES is pretty similare and is basically copy
pasting this new design.

We still need to see if in some context it would make sense to add
a mode where we would commit any changes ourself at the end of our
operation for basic use cases.

Removed APIs:
  ges_timeline_enable_update
  ges_timeline_is_updating

... Not the other way round.

  + Add and enhance debugging info on the way

The user should not be responsible for removing the GESTrackElements from
GESTracks, instead, removing it from a GESClip should imply removing
it from any GESTrack it is in.

This patch changes sensibly the behaviour when we remove a
GESTrackElement from a GESTrack, not remoing it from the GESClip it is
in. *But*, users should never remove a GESTrackElement from a GESTrack
anyway. The testsuite has been updated to that new behaviour.

We already had the infrastructure so the user can have the control over where to add
the elements (through the "select-track-for-object" signal). We now make use of that
signal everytime a GESClip is added to a GESTimelineLayer. This make user's life easier,
and object responsability clearer.
