expression encoder sdk - mp4 format problem
- I'm trying to encode mp4 files using the sdk but an InvalidMediaFormatException is thrown (Message: Apple QuickTime is not installed), apple quicktime is installed and when using the application i manage to encode the files successfully - Uninstalled quicktime and reinstalled it but the problem persists - any ideas? thank you
Toutes les réponses
Are you running your application as the current user or as System running as a service perhaps?
Regards
Dean.- well i tried both, i started working on a windows service and then switched to plain old console app. I forgot to mention that i'm working on a 64bit vista machine and installed expression blend 3.0 beta a few days ago. i'll uninstall and reinstall everything (expression apps and quicktime that is :) and try again. when running as a console app i assume that it is using the same identity the expression app is using (interactive user) but is a very interesting point for when it will be running as a service if it works.
i'll try uninstalling and reinstalling everything and post the results here, thank you. - ok, uninstalling and reinstalling the apps didn't help. BUT it is definitely a problem with my machine (the configuration perhaps - vista64bit and quicktime !?) because i just tested the console test app on a different machine (32bit windows 2008 server) and WORKED just fine.

giannis So for some reason QuickTime is not being detected on your 64-bit machine. This definitely should work as a whole bunch of us here work with 64-bit machines. Can you run the 32-bit version of Regedit on your 64-bit box to check something. You can do this by running
c:\Windows\SysWOW64\regedit.exe
Then navigate to HKEY_LOCAL_MACHINE\Apple Computer, Inc.\QuickTime and see if that is there with appropriate values?

Dean.- i did find the entries in the registry but i'm not sure what the appropriate values are, could you please elaborate.
btw i ported the app back to windows service and works really good - i really really like the expression encoder api.
best regards,
giannis - Thanks for the comments. I'm not sure what else to suggest as it looks like you've tried uninstalling and reinstalling QuickTime. I assume you're installing the latest version? We've certainly used QuickTime and Encoder on 64-bit machines, so it should work.
Regards
Dean.
