#2 Quicktime and URLs
The problem: QT4J 6 on both Windows and Macs will
not play files from http URLs. This is a real problem for
our work.
---------------------------
I submitted the URL problem to Apple Bug Reporter in
August. I was told
told that it's "a known issue that is currently being
investigated by
engineering." I would have thought more people are
trying to access web
content, but judging by the amount of discussion this
issue has
received, it must be a fairly unusual way to use QT4J.
From what I can
tell, QT4J is attempting to download the entire file into
memory before
it begins playing. Interestingly enough, if the file is being
streamed
by a streaming server, QT4J handles the URL correctly.
Ed,
Here's what I got back from apple. I haven't followed up on it
lately. I
think you're right about earlier versions. QT5 didn't have the
problem.
It's good to know someone else thinks something goofy is
going on
here... Larry

Subject: Problems playing from URL
I've got a JWS application
(http://iris.lib.virginia.edu/tibet/tools/quilldriver/) that uses
either
Quicktime or JMF, and although I've got the Quicktime
version to work
with local media files, it will not open http URLs.
I get the same exception (see below) whether I run it on
Windows (JDK
1.4, QT 6) or Mac OS X (10.2, QT 6). I vaguely recall
some discussion of
this issue a while back: is there a bug with QT4J 6 such
that it won't
play URLs? If so, I sure hope it will be prioritized by the
QT
development team.
Ps. I wrote a couple of days about some other non-fatal
exceptions I was
having on the Mac, thanks to those who responded, that
turned out to be
a non-issue. This one seems pretty serious, though.
