Hi BJ,
I get the same result : src seems to contain only the part
{{VideoPathDictionary##$(origin)$}}. It looks like $(filename)$ is
discarded !
I made another experiment.
I put a "path" field in the video tiddler ; path=../../Videos/DVDSubject1/
I modified the template :
\define videocall()
<video width=480 height=384 controls="controls">
<source src= "$(path)$$(filename)$"/> <---- with quotes !
</video>
\end
<$set name="path" value={{!!path}}>
<$set name="filename" value={{!!filename}}>
<<videocall>>
</$set>
</$set>
This time it works as expected !
But it's not what I intended to do, as I wanted to centralize the paths in
a dictionary tiddler and not put them in each tiddler.
Anyway thanks for your proposal
FrD
