QuickTime Videos display no picture (audio works)

[SoItBegins]

I'm using SheepShaver, and I'm having problems with Quicktime Player as well as any game that plays video clips (example: the opening movie for Oregon Trail II.)

The clip's sound plays perfectly. The video does not appear, giving a black or white screen depending on the app.

The relevant specs:
QuickTime version: 2.5, 4.0.3, 4.1.2 (tried with all)
Mac OS version: 8.5/8.6 (tried with both)
Host OS: Mac OS X 10.6 (Snow Leopard)
SheepShaver Build: 2.4.20140201

I tried a clean install of Mac OS X and still nothing.
(When I try the same apps on Basilisk II with Quicktime 4.0.3, the video works perfectly.)

What might be causing this problem?

Hi,

Might this have to do with the number of colors you have set the display to?

Best,

funny you mention that, ive been fighting it too...

I think 8.0 and 8.1 play nicer... i want to try a m68k build to see how it builds

[kikyoulinux]

The latest version of QuickTime that is compatible with SheepShaver is version 4.1.2. And works with oldworld rom.

[SoItBegins]

Tried it in both Millions and 256 Colors. No difference. I might try installing Mac OS 8.1 next, Basilisk II is running that.

[SoItBegins]

After going to a lot of trouble to reinstall 8.1— nope. Still a blank.

EDIT: And playback is choppier. –_–

Ok first let's try System 7.5.3 ...




This is the 7.5.3 that is available on Apple's site for download, I just went ahead and stitched it together to make it into an ISO that boots on emulators, and may even work on the real thing as well.

The Player I fished out of a MacOS 8.1 VM image, so I'm not entirely sure.

Anyways, the bundled QuickTime 2.1 works great with the Introducing the Quadra, QuickTime video from here.

I used oldworld ROM's and the video plays flawlessly.

Code: Select all

$ md5 8500v1.rom 
MD5 (8500v1.rom) = dfebb8fdad4124e02608429d98bf349b
$ md5 8500v2.rom 
MD5 (8500v2.rom) = 2623a0c438045ea04d2cc67310c97743
$ ls -l *rom
-rw-r-----@ 1 jsteve  wheel  4194304 19 Jul 12:21 8500v1.rom
-rw-r-----@ 1 jsteve  wheel  4194304 19 Jul 13:04 8500v2.rom
-rw-r-----@ 1 jsteve  staff  1900274 19 Jul 12:46 NW.rom

The NewWorld ROM can't boot up 7.5.3.

Oh I forgot to add, it works in 1bit -> 24bit, and everything in between.

[neozeed]

So both QT 4.03 and 4.12 in OS 9.04 act strange. Using a NewWorld ROM you can get the video, but no audio. Using an OldWorld ROM, you get a white screen,(ie no video) but you get the audio...

[neozeed]

OK updated to MacOS 8.0, QuickTime 2.5 still worked just fine.

Upgraded to QuickTime 3.0


Works great in 256 colours. Changing to thousands crashes out Sheep. The key seems to be changing depth before launching a QT application.

Millions either Crashes Sheep or gives an error type 10:


So as long as I set the mode, and colours, shutdown, boot backup and play it's ok. Any changing of colours makes it mad. And millions of colours doesn't work.

The NewWorld ROM I have won't boot 8.0

[neozeed]

QuickTime 4.0.3 pretty much has the same limitations as 3. On 'Millions of colours' it gives a white box, and a video codec issue, but the audio plays. It works fine in lower depths.

If you switch on the fly it'll crash.

[neozeed]

QuickTime 4.1.2 is pretty much the same thing. Don't change colours, and it won't do Millions. Other than that oldworld rom, and 8.0 seem OK.

[neozeed]

System 8.6 with new world or old world.. It doesn't matter none of the surfaces render.



By default it had QuickTime 3, I tried 4.0.3 and 4.1.2 and it behaves the same way.



On the first play you get a white spash that you have to click in like crazy to get it to continue. Again it doesn't display the video content.

I notice on boot the graphics acceleration has an X through it, so it may be tied in there.

[adespoton]

Hmm... have you tried it with all non-QT extensions off? I thought that the graphics acceleration extension wasn't supposed to be used with emulators...?

I dumped all those in 8.6, and it made no difference.

I think the fundamental difference between 8.1 and 8.5 (and beyond) is the increased PowerPC code, while SheepShaver fundamentally is Basilisk II, which hooked into the 68000 code. And seeing how little of the Ethernet code Sheep actually hooks into vs Basilisk, the more they moved into PowerPC code the more it fell apart. Which I guess is the fundamental reason 9.2 won't work at all.

Between 9.0.4 and 9.1 memory management in MacOS was changed. From 9.1 onward a MMU is needed and SheepShaver does not emulate a MMU.

Yeah, I suspect as OS 9 got more and more PowerPC native, even with the MMU, Sheep wouldn't run it or run into more issues... I just remembered something from a hackintosh where it didn't support the proper 3d acceleration that QuickTime would just show a blank screen. Which is what I think is going on here. I guess if you really wanted 8.5/8.6/9.0 you could try to remove all the drivers, and paste bits in from 8.1 although I suspect that won't work so well.

Speaking of SheepShaver and hackintoshes, what is the 'best' Xcode to try to build it with?

[Ronald P. Regensburg]

From the current source code you can build SheepShaver on OSX 10.6 (latest 10.6.8) with Xcode 3.x (latest 3.2.6). See: http://www.emaculation.com/doku.php/com ... r_basilisk
