Unable to open MKV after 1.2.3 update

[Harfish]

I upgraded to Lion over the weekend and didn't have any issues with Perian until today when I installed the 1.2.3 update. I only use Perian for one specific task: converting 720p MKV files into Xbox 260 compatible MP4 files. My process, which has worked for years, is to open the MKV file in Quicktime 7 Pro, then export the file to MP4 using the passthrough setting.

However, after upgrading to 1.2.3 Quicktime 7 now tells me that my MKV files are "not a movie file". I've already hit the uninstall button and downloaded and reinstalled Perian 1.2.3 but no joy.

Any suggestions?

i just tried opening an .MKV in MPEG Streamclip that might might be able to do the job for you

We need a sample to investigate this. See the end of http://trac.perian.org/.

Yeah, I have similar problem MKVs were playing just fine yesterday but not that I installed the Perian update the playback is laggy and paused. I'm on 10.4.11

We are not putting any further updates out for 10.4.11.

Oh noes. Can you link me to v.1.2.2 then? it works a lot better. Thanks.

The download should still be up, just change the version number to 1.2.2

I'm experiencing the same problem with all my MKVs that worked with 1.2.2 under Lion. Even the ones I'm currently encoding myself with Handbrake using the high profile are experiencing the same problem.

Even the ones I'm currently encoding myself with Handbrake ...

Good, then you should have no problem with the post made over 2 weeks ago:

I'll produce an example when I get home from work this evening.

I just noticed it works fine with 1.2.3 on my Lion work machine which is identical to my Mac mini at home also running Lion. Rolling back to 1.2.2 did not fix the problem on my home machine. Are there application support or preference directories/files I can delete that might be causing an issue?

Not likely unless you were using the hidden preferences via the defaults command. All prefs are stored in Library/Preferences/org.perian.Perian.plist. You should also check for any other QT components that you may have installed.

Looks like I can play SOME MKV files but some files still give me the warning about needing QuickTime 7. How do I create a sample for you guys? What software do I need?

[Einkoro]

I can't seem to duplicate the issue now after removing 1.2.3, installing 1.2.2 and then upgrading to 1.2.3 again. All the mkvs giving me problems before are working fine now.

Issue seems to back. Two samples and a media info dump of the first. 2nd one is large enough (25gb) it seems to crash media info.
