I have a quick question about metadata for derived tracks.
The addDerived method doesn't add any properties to the MediaPackage
describing the derived track. How exactly do I add this information to
the new tracks? Or am I supposed to not worry about it?
Thanks,
Robert

Excellent. I had already found workspace.put(), but I wasn't sure
about the Tracks.
Thanks very much!

The idea is that you put the file in the workspace via:
Workspace.put(String mediaPackageID, String mediaPackageElementID,
String fileName, InputStream in)
which returns a URI to the file. You then add a track to the
mediapackage with that URI. Using addDerived helps others
understand that the new track was derived from the original:
Track splitTrack = (Track)
MediaPackageElementBuilder.elementFromURI(uri, Type.Track,
MediaPackageElements.PRESENTER_SOURCE);
mediaPackage.addDerived(originalSourceTrack, splitTrack);
Then return the mediapackage as part of the WorkflowOperationResult.

Hello All,
I'm working on an operation handler to take the video streams
from NCAST cards and split them into two files. The idea was
to write this as an operation handler and perform the
splitting during processing. Currently, I have a reference to
the workspace injected so I can run a gstreamer pipeline to
split the file locally, but what is the best way to insert the
resultant pair of videos back into the workspace? Do I add a
new Track to the MediaPackage, or do I use the addDerived
method to add a modified Track? (I'm sorry but I'm a little lost).
