x264 quicktime component

[Blue_MiSfit]

Hey all,

I noticed there is an x264 quicktime component for Mac OS X. Unfortunately it has not been updated since January. It is exceedingly useful for lossless compression of uncompressed HD masters, but unfortunately it does not work with the new Intel macs.

Does anyone have a line on when that might be updated to run on the Intel macs, and hopefully have an updated codebase? It would perhaps be the ultimate in lossless compression on Mac OS X, aside from its rather basic colorspace format - most uncompressed HD is YUY2 4:2:2 10 bit.

Shouldn't be that hard to update, just a few changes and re-link. Not sure about updating to Intel though.

Figured I'd post here to note that I've updated it to a universal binary, as well as fixing some long standing bugs. It isn't extensively tested on Intel Macs since my primary computer is a G4, but it should work (bug reports welcome.)

I'll take a look at adding support for other colorspaces (YUY2 is actually better supported in the QT framework than YV12, so this definitely makes sense) for the next version.

Fantastic! I'm going to try it out. Do you know anything about the Perian component? They want to integrate libavcodec decoding in QuickTime.

Ops, bad news, it crashes as soon as I select the codec in the QuickTime MOV exporting window... :( I'm on MacOS X Intel.

Is this on all movies, or is does the movie happen to have an odd dimension? I just got a report that it'll crash if the movie's 346x259 for example (will investigate tomorrow.) If it's even with mod-16 resolutions, could you post/pm a crash log?

Regarding Perian, I'm actually one of the devs. I have been trying to get decoding high profile H.264 in MP4/Matroska to work through it, but that hasn't been going too well. I'm hoping I'll get it working for the next release though.

It's a 624x352, so it's mod 16. I didn't get the crash with a smaller clip (352x288). So it's strange. If you tell me how to get the crash report, I can send it to you, or we can stay in touch by email.
Thanks again

If a dialogue comes up notifying you of the crash, there should be an option for "Report..." that brings it up. If not, try opening Console.app and checking the last few lines for something that starts like "Failed assertion".
