Thanks to Richard Gaskin and Jacqueline Gay for their thoughts on the current
problem in creating standalones with referenced QT movies using LiveCode 6-7 on
Mac. Richard and Jacqueline have through the years been helpful and generous in
providing their expertise.
Here is a summary of what I find with trying to create standalones with
referenced QT movies:
CREATING REFERENCED MOVIES USING LC ON MACINTOSH:
1. LiveCode 5 will show referenced Quicktime movies, including the ability to
maintain relative paths in the LC movie player, so that the standalone can be
distributed to other computers, whether Mac or Windows.
2. LC versions 6 and above, however, will not allow relative paths, when
creating with Mac. E.g. consider this hierarchy in a Mac stack that you want to
convert to a standalone for distribution:
FOLDER
MyMainstack.rev
MEDIA
MyMovie.mov
If you want to refer to the movie in the LC Quicktime player, with the idea of
creating a standalone for distribution to other platforms, you would want to
change the movie player’s absolute path to a relative path:
Media/MyMovie.mov
However LC versions on Mac above LC 5 will not allow this. There, if you open
the LC movie player and change the absolute path in the LC movie player to the
relative path in the filename field, then close the Property Inspector and
immediately open it up again, you will find that LC has reverted to the
absolute path! Thus, you can’t create a standalone with a referenced QT movie
for distribution in the LC 6-7 series, since the movie path always resets the
relative path to an absolute path.
This problem is not resolved by unchecking “Always use absolute file paths for
images” in the LC Preferences, or by putting the relative path into the
“non-stack files” section of the Copy files sections of the Standalone
Application Settings, or by setting the DontUseQT global property to false. I
also don’t see how setting the defaultFolder to the Documents folder would help
in this situation either, where a person to whom the standalone is distributed
would be unlikely to use the Documents folder.
THE BOTTOM LINE: To created standalones with referenced movies on the Mac for
distribution, you would do best, until the LiveCode team resolves the problem,
to use a LC version not greater than 5.
CREATING REFERENCED MOVIES USING LC ON WINDOWS:
On Windows, LiveCode version 7.0 WILL maintain the relative path in its stacks
and standalones, so you could create the standalone on Windows with LC > 5 and
transfer the standalone to a Mac, where the movie will play.
