Re: version 1.2.2 will not install

Yes, this is a known issue in System Preferences which is entirely its problem. I believe it could be worked around in the updater, but hopefully future versions of OS X will fix this crash.

Re: Cannot Build

The project will be updated for Xcode 4 compatibility soonish. I would expect the current one to work with 3.2.6, though.

Re: MP4 just audio no video

Try running this in Terminal (cmd-shift-U -> Terminal):

Code: Select all

defaults write org.perian.Perian DecodeAllProfiles -boolean YES
If that doesn't work, can you post the file to Mediafire and link it here?

The command to undo the above:

Code: Select all

defaults delete org.perian.Perian DecodeAllProfiles

Re: Could not open FLV file after installing Perian

Opening things with that app should definitely work, but if it doesn't I don't know what to do about it. Maybe log out/log in again?

Re: Front Row + Perian + MKV + Subtitles = Stuttering image

It's a problem in Front Row - there's not much else that can be done. You could try another full screen player like Plex.

Re: Transcoding MKV files stops after a few seconds

It sounds like you should wait for kMovieLoadStateComplete. This won't add much extra delay to the encode.

Re: VP7 or VP8 codec

FFmpeg doesn't support VP7. The next version of Perian will support VP8, but not VP7.

You could always ask VP7's new owner Google to post the spec.

Re: "vo3+" (0x6771) audio encoding>No Sound: Plans to support?

XiphQT works fine with Perian. Neither support Vorbis ACM, though. That is an extremely rare audio codec and I think everyone assumed that, if they didn't support it, it would go away. Unfortunately I'm not willing to implement it if VLC or MPlayer haven't been able to. You might be able to fix it w...

Re: Output Levels

Mac gamma is 2.2 now, just like Windows. Except that Windows 7 is still mostly uncalibrated (you have to search for "adjust gamma" in Control Panel; it won't read it from a color profile). What kind of file is wrongly tagged here? Since literally no YUV content uses 0-255 range, assuming i...

That's Xiph FLAC. Perian should support that in the next version (though it hasn't been added yet); in the meantime try http://xiph.org/quicktime/.

Re: Output Levels

QuickTime properly converts 16-235 YUV to 0-255 RGB - this uses the entire black range. I don't think we have a way to signal 0-255 ("full range") YUV, but nobody uses that, and trying to play back something like that would only cause the contrast to be too high. The only real effect of th...

Re: Alida Video Game Lacks Ambient Sounds, Music

You'd need QuickTime.framework, not QuickTime Player. It's pretty integrated with the system, so replacing it with a different system's version probably won't work…

I can look at 10.4 sometime, but not for another week or two.

I also set the cpu target under the CFLAGS_i386 to prescott This has no effect at all - the cpu target is set to pentium-m to target AppleTV, but the only code generation change between that and the default for the Apple compiler (which is optimal for current Macs) is a slightly longer sequence gen...

Re: Alida Video Game Lacks Ambient Sounds, Music

That file (which uses the IMA 4:1 codec) plays in QT 7, QT 10, and mplayer for me. The last two don't use QT 7, I think. The first might be because I reenabled legacy codec support once, though. If you open it in QT 7, do you see anything in the inspector window? (cmd-I). It will either say IMA 4:1 ...

Perian doesn't play WRAW but the system should handle it. If it's needed for QT10 support we might be able to add it.
