If you want a custom clip then you have to subclass GESClip,
This class was pre historicall and only used for testing purposes, we
have GESTestClip for that.
https://bugzilla.gnome.org/show_bug.cgi?id=706855
The idea is that we should first play until the time we reach the first
position, at that point we PAUSE the pipeline, then, afterward do the
seeks as asked.
If we get the position before the ASYNC DONE, just accept it.
Add a new test that creates a given number of layers. Each layer has the same
assets / clips shifted by a different amount in the timeline. Alpha and volume
properties are different for each layer. This test is similar to the mixer
example in:
http://gist.github.com/MathieuDuponchelle/5736992#file-mixit-py
We should be able to add more clips to each layer, but this example test only
tests mixing 1 clip across 4 layers.

This second set of seeking tests performs the seeks in a PAUSED
pipeline. After all seeks are successful, the pipeline is resumed so that the
test does not timeout.

- Use g_list_remove_link so that ordering of seeks is not mandatory
- use g_slice allocator for SeekInfo structs
- Fix leak in freeing seek list
- Check for NULL seeks at end of test, otherwise fail and free failed seeks
A Seekinfo structure consists of 2 fields:
- position: the position to seek to
- seeking_position: the position to perform the seek from
Seeks can be appended to a global list e.g. from code:
seeks = g_list_append (seeks, new_seek_info (0.2 * GST_SECOND, 0.6 * GST_SECOND));
seeks = g_list_append (seeks, new_seek_info (1.0 * GST_SECOND, 1.2 * GST_SECOND));
seeks = g_list_append (seeks, new_seek_info (1.5 * GST_SECOND, 1.8 * GST_SECOND));
The get_position callback checks the current position and attempts to perform
the corresponding seek with gst_element_seek_simple
Those are test with real media files, they are run separetely from other
unit tests using the make check-integration command (can be done from
the toplevel directory)
Currently we can end up overflowing the start of others child of our
parent, avoid that making sure we can set our start to what was
requested by the user before actually doing it
+ Add a test
Check if an object rthat has already been freed has been destroyed is not safe.
Add a helper function that uses weak reference to check that objects that are expected
to be destroyed when unrefing an object are actually destroyed.
This exact same method will be needed in GESGroup, so we should have the method
in the common parent class.
