[gst-devel] kenburns plugin update - now a general video transform plugin

[Lane Brooks]

I have an updated kenburns plugin with the following changes:

- I dropped the internal controller. Now you use a GstContoller to 
control the 'xpos', 'ypos', and 'zpos'.
- I added rotation transforms as well. You can now also control an 
'xrot', 'yrot', and 'zrot' parameter.

You can check out a video I put together that show cases these features 
at http://www.youtube.com/watch?v=JFm8Rra4xzQ. This video first shows 
the translation and rotation features with the 'xpos', 'ypos', 'zpos', 
'xrot', 'yrot',and 'zrot' parameters hooked up to LFO's with an stmpe 
video test source. It then shows some sample kenburns effects, which use 
the 'xpos', 'ypos', and 'zpos' parameters hooked up to linear 
interpolating GstControllers. It then shows some sample video 
transitions that also make use of the position and rotation parameters 
hooked up to linear interpolating GstControllers.

You can still clone the source code at:

Given that the feature set has grown beyond Ken Burns effects, I want to 
rename this element to something else. I was thinking 'videotransform' 
but am open to other suggestions. One reason against videotransform is 
that there is already a base class in gstreamer call GstVideoTransform. 
It is not exposed to the user, so it only a potential confusion for 
developers. But if there is a good name that is not a potential 
confusion, I would go with that instead.

After I decide on a new name and hear any additional feedback, I will 
post a patch to gst-plugins-bad.

Thanks,
Lane
