I've run into a discrepancy I hope we can clear up. I've taken some
of the code from Chris Adamson's excellent book and created a program
which takes two existing Quicktime movie files and places them one
after the other in a new Movie object via track manipulation. the
Movie object in question is created like so:
QTFile movFile = new QTFile (new java.io.File("built.mov"));
Movie builtMovie = Movie.createMovieFile(
movFile,
StdQTConstants.kMoviePlayer,
StdQTConstants.createMovieFileDeleteCurFile |
StdQTConstants.createMovieFileDontCreateResFile
);
once I add the tracks in to the builtMovie object, I insert an
HREFTrack that placed at the beginning and has a duration of the
first movie. I then want to flatten the builtMovie object into a self-
contained Quicktime file with no dependencies, which would look
something like:
T0 T1 T2
+--------------------+----------------------------------+
| Quicktime movie #1 | Quicktime movie #2 |
| HREFTrack | |
+--------------------+----------------------------------+
to give you an even clearer picture, here's a screenshot of the
Movie Properties as reported by Quicktime Player:
the problem is that I've found a discrepancy between the movie file
that's created by calling builtMovie.flatten() and by calling
builtMovie.convertToFile() with StdQTConstants.showUserSettingsDialog
as a flag, and selecing "Movie, Self-contained". the difference is
the HREFTrack - it works as expected when I call convertToFile() - I
can open it in a browser, click on the movie while it's playing, and
have the URL open.
if I play the movie file that's produced by flatten() in a browser,
it plays, but is not clickable. nothing happens.
I've also tried using MovieExporter to save the movie that way,
which actually blows away the HREFTrack, so that doesn't work for me,
either.
in the light of further investigation, I examined the sizes of the
files - one produced by convertToFile() with the user settings
dialog, and one with flatten(), and they are indeed different:
-rw-r--r-- 1 jklett jklett 20364941 Aug 23 17:48 convertToFile.mov
-rw-r--r-- 1 jklett jklett 20379333 Aug 23 17:46 built-flatten.mov
so what I'm really looking for is how to precisely mimic what's
being set by the user settings dialog when one picks "Movie, Self-
contained".
I can provide more code if necessary. thanks to all that read this far!
