I know what you mean Alex. I have built many applications for public usage-
and for a lot of users at that. I found the best way was to use the QTJAVA
environment variable. It seems the variable has changed; its surrounding
QUOTES in QT7 have gone- HURAY! (so that's cool). Everything pre QT7 has
Quotation marks around the variable and that became a bit of a pain.
Another way is to use InstallAnywhere (costly mind). They worked with Apple
to get QTJava to work- it tried to find the QTJava on the system, if its not
there it will launch your QuickTime installer...
For browsernet stuff (say your user has to download the application) I cheat
and embed a QT Movie into a webpage in that movie I have an bit of xml that
asks for the QTJava component- if it cant find it that QT will download and
install that component. If the user has the component the movie links to the
download page ;) cheeky but always seemed to work... WebStart: humm will we
can just full cheat here- but then that brakes the license, so same as
browsernet.
Yes: its not all convenient, but then nothing is... you cant ship the
QTJava.zip within your own installer (see license of QuickTime)...
I'm sure Apple still love us, and will come and save the pain... not sure
what they can do at this point mind... all older QuickTime installs 6, 6.5
on users computers will stay the way they are (they do tell them users there
is a new version of QuickTime, they just don't want to update).
QTJava or JMF... Well I know what gets my vote :)... Come QTT give us a nice
Capture back- go on, go on :).. Buy you all a beer when I'm next in Cally...
What's really funny is that a Mobile Phone has less hassle with media
playback then Windows :) hehehe... true mind... even 3d is a snap, shame I
cant work out how to make a call on it...
Tops- keep smiling dudes...
