Perian and 10.6

[SHRIKEE]

The resolution is pretty high, say 1280x720 or 1280x540. The lower res files are usually around 700x500 (or even lower)

The iMac has an ATI HD2600
MBP 13" nVidia 9400M
MBP 15" nVidia 8600GT
(all with their own 256MB ram, all machines have 4GB Ram installed)

With Leopard it works fine on all 3 machines, no hick-ups. Smooth playback. I play the files from a networked disk usually.
The 13" and iMac shipped with Leopard originally. It worked fine then, since the SL upgrade it has been crappy. Same for the iMac. I think with that we can conclude that either the QT bit you mentioned is acting up or something is wrong with the codecs. I hope the codecs... Since that's easier to fix. Right?

Which version of QT would crash you'd say? The older one i mean. Might be before my Mac days, but i've never noticed something like this before.

Going to bed now, feel free to PM/email me if you need more info.

I was curious if the hardware accelerating GPUs made any difference. It seems it did not.

I think it was around QT 7.1 or something like that. It was a while ago. I can tell you that the AppleTV has one that still crashes with high profile H.264. Issues like this is why Perian included a H.264 decoder in the first place, where overriding Apple's was a tricky process.

Now that QTX is out, the question is can we still override Apple's component, especially if it's crashing? I believe that Apple's component is using the QTX plugin architecture (which is not public), where as Perian and everyone else must use the old QT architecture. So the question is, can a QT plugin override a QTX one?

None what so ever, its a software problem for sure.

Any news/progress on a 64 version of Perian (or whatever is required to make it work with QTx).

Not pushing, just curious...

Thanks in advance!

Hello everyone! New member here, and new Mac user as well.
A month ago both a Mac Mini Intel Core 2 Duo 2Ghz, 2Gb Ram to use as a Media center for home. Specially tu run all the kids movies for my son. As well, I have other DVD rip movies that I had in disc that I convert and back to store them all in a External USB hard drive. Everything worked perfectly with Front Row (video, audio, quality) until I upgraded to Snow Leopard.

What I get now, viewing movies, are jumping images, less video quality and crappy sound. I don´t know what could be the problem, but reading your posts seens to be the compatibility of Perian with SL 10.6.1 (that's my guess, I am not a Mac expert what so ever).

My idea is to uninstall all video codes, audio codecs and inclusive Perian, and try to se what happend. If not I will install Perian again, and try.

Besides that, What else could I try to meke it run movies like before?

Thanks in advance to everyone.

Cheers

HI! Using the application I am now able to open .mkv files. However, when I opened it in Quicktime , the video quality was tremendously different from opening it in VLC. The picture in Quicktime seemed a light brighter, and because of that, some detail was washed out. Does anyone else have this problem?

PS: It might be hard to see in the attachment, but I assure you the quicktime one is brighter and a bit washed out. Pay attention to the browns and greens (It might help by standing back a little to see the difference.) !

Is there any chance of Perian enabling real QT X playback for h264 mkv files at some point down the road, without falling back to the QT 7 process for playback?

I have a bunch of 1080p files with a relatively high bit–rate that won’t play without dropped frames on my machine (17" Unibody) so I was hoping for the hardware decoder to be used.

I also cannot open .divx files on Perian with QuickTime 10 running on Snow Leopard

When will this be fixed?

Hi, I'm trying to verify whether my mac mini output's 5.1.

I found this trailer that has 6 channel AAC output:
http://movies.apple.com/movies/wb/incep ... 1_720p.mov

It only outputs in stereo when I use QuickTime Player 10. Not sure why. when I play a regular movie via DVD player, I get 5.1 output, so I know the wiring is correct. (stereo supports DTS and dolby digital)

I've installed perian using the following instructions:
http://www.cod3r.com/2008/02/the-correc ... quicktime/

Just a note, not sure if it's completely relevent, but I don't see the 5 channels on the midi output as shown on the screenshot.

I've read through several postings on various sites and have no luck debugging it. I've installed and re-installed perian several times, but still no progress.

First question, is it suppose to play in 5.1? I'm not too familiar with the various audio encoding.
Second question, is there another video / trailer that I can verify against?

Any help would be appreciated.

I found this trailer that has 6 channel AAC output:

That will not give you 5.1 over an optical link. Essentially only DVD standards are supported which means stereo, AC3, and DTS only.

but I don't see the 5 channels on the midi output as shown on the screenshot.

Neither the screenshot nor the text include anything about 5 channels, do they?

First question, is it suppose to play in 5.1? I'm not too familiar with the various audio encoding.

No, not with AAC content. Notice, the site you linked discusses AC3 and DTS only. This does not extend to AAC.

Second question, is there another video / trailer that I can verify against?

You need something with AC3 or DTS content. Apple uses neither with the exception of their HD content on the iTMS. Try using handbrake on one of your DVDs using the AppleTV preset if you want something to test.

ANy sight on a compatible perian yet? Anything that we as a community can do?

[Mr VacBob]

You could read the first post, or say what problem you have.

[SHRIKEE]

of you should read the thread...

[dm33]

Any news on when this might get fixed?

I ended up having to uninstall Perian 1.1.4. Basically its totally broken on Snow Leopard. There should be a warning on the main page of the Perian website.

Did you read the first post of the thread you just responded in?

[SHRIKEE]

Despite of what the first post says, Perian is NOT working properly in either QTP10 or 7. Most codecs do not work or make both players crash.

If you read through the posts you can find various posts of me and others pointing out several files that do not work which did work under leopard or even tiger.

[gbooker]

Shrikee, despite your issues, Perian does work with QTP10 and 7. You seem to stand alone as the only one with crashes, as I have not seen a single crash log (even from you I might add).

Also, if you read through the posts, you find that a majority are issues in the new QT Player refusing to open other file types or an audio codec not loading, both issues which are addressed in the first post as well as workarounds listed in this thread.

Given that this thread has devolved into demands and gripes rather than helpful information, I'm locking it.
