Hi all,
I'm having a couple of issues implementing the DVDPlayback framework
in a kiosk app. First of all I see a lot a garbled graphics. The
screen goes green and all I see is interlaced junk. Not always, but
quite often, and when I do I usually need to force a shutdown of the
computer. It seems this is more likely to happen after
loading/unloading the media a couple of times. The first time I play a
disc/dvd folder everything usually works as expected. The framework
doesn't report any error when this issue occurs.
My code is pretty much identical to the one in the CocoaDVDPlayer
sample project, except I create the the video window when loading
media and release it when the media is closed. I also have a Quartz
overlay over the video window to draw OSD. But even if I re-use the
same window during the whole session, and remove the overlay, I still
get these errors, so I don't think it is related. I can post the code
if you like, but something tells me this is more of a general issue
with the framework. Perhaps fullscreen playback isn't allowed at all?
Do I need to flush the video window somehow before loading new media?
The second issue I'm having is an error code -70017:
kDVDErrorMissingGraphicsDevice. I begin a DVD session when entering
fullscreen and terminate the session when exiting again. Now if I
re-enter fullscreen and try to play a disc I get this error. Always.
If someone would care to share his or her thoughts on this I would be
much obliged. I have been banging my head against the wall for several
days now. Thanks a lot in advance.
F.
