I think this should work
\define videocall1()
<$set name="mySource" value={{VideoPathDictionary##$(origin)$}}>
<<videocall>>
</$set>
\end
\define videocall()
<video width=480 height=384 controls="controls">
<source src= "$(mySource)$$(filename)$"/>
</video>
\end
<$set name="origin" value={{!!origin}}>
<$set name="filename" value={{!!filename}}>
<<videocall1>>
</$set>
</$set>
cheers BJ
