---------------------------------------------------------

Nope.  The required bits for the Epiphan MCAs has been worked into the default 
workflow (which is using a special flavour, but that's invisible to the rest of 
the system).

Edit:  Also, the files are no longer deleted, which is really helpful in 
diagnosing things!

> As part of development for the new Epiphan capture devices we needed a new 
> media flavour:  presentation/multitrack.  This flavour marks files which can 
> contain multiple video and or audio tracks (two video and an audio in this 
> case) that will need to be split before further processing can occur.
> The current handling is to process as best we can using existing workflows.  
> This is somewhat problematic in that it does not generate a playable file (or 
> indeed any file at all) and deletes the source files at the end of the 
> process.
> To mitigate this we should implement an ensure_complete operation which will 
> not succeed until the mediapackage can be processed successully (ie, an 
> output file is generated).
