Description

Currently using Perian 1.0b4. Quicktime currently fails to get all info from the majority of my avi xvid videos. I have included a screenshot of quicktime's get movie info dialog for such a file. Please note the Onbekend (Unknown in Dutch) instead of the usual Millions.

This also has ramifications for a.o. Democracy which uses quicktime in conjunction with Perian to create thumbnails in it's library. The same issue has been present in 0.5 and remained so throughout Perian's 1.0 betas.

2 sample files (1 showing correct info in QT and a thumbnail in Democracy, and 1 which does not) are availabe in Democracy's bugtracker (#7207) https://develop.participatoryculture.org/trac/democracy/ticket/7207.

I am currently on 1st generation black MacBook? with 1.25GB ram, using a fully updated OS X.4.9 with 1.0b4. Only installed QT components are MPEG2, Flip4Mac WMV Import/Export, AppleIntermediateCodec?, and RealMediaExporter? (which doesn't even work btw).

movie info dialog showing unknown

I confirm. The sample file indeed shows "unknown" in the info.

MPEG4 isn't "millions of colors", Unknown is probably the right thing to say...

  • resolution set to invalid.

astrange is correct, and as such, this isn't a bug.

this bug is not about semantics. the wording in the info dialog is just a result of the underlying problem, but i lack the knowledge to pinpoint word it correctly.

I'll look and see if Quicklook can make thumbnails.

The depth field is set to 12 in that file, and QT Ice Floe claims it should be 24 for non-alpha formats. I guess we should be setting YUV video tracks to 24 for now*, but I'm not quite sure how to tell if they're YUV during import, and we do need to keep the value from the original file for 16-bit RGB video or such things.

* YUV+alpha does exist and would use '32', but I don't think we can handle any of those anyway.

mkv sets depth to 24 for everything, but I don't know if that breaks RGB video.

  • status changed from reopened to closed.
  • resolution set to fixed.

(In [855]) Use depth=24 for files with depth set to 12. Closes #193 although it's not really a complete solution.
