mmreader failing for me on 32 bit Mac
in [Matlab]

Prev: reading mov video files
Next: Undefined function or method 'matscale' for input arguments of type 'double'.
From: Thomas on 9 May 2010 08:15 I'm using mmreader on a Mac, using 32-bit version of Matlab 2010a. The OS is Leopard (not Snow Leopard yet). I'm reading in *.mov files that were created on the Mac. The *.mov files all play perfectly in QuickTime. It is failing for me. I get either interlaced fields instead of frames, or rgb data that is offset by some strange amount. Basically, the frames returned are jumbled, but you can see that they were trying to be images. I have alerted MathWorks support. This was caused by an upgrade to QuickTime that caught MathWorks off guard. It is a problem with all the macs in our lab, so it isn't just my machine. Has anyone else found a work-around for this problem? - Thomas
From: Thomas on 9 May 2010 09:39 I should mention that there is a workaround: Use QuickTime to export the entire video to a set of sequenced images. This takes a lot of disk space, but can be used for short video clips.

Hy thomas, I think I may have a similar problem. I'm running Matlab 2008b on mac osX Leopard. A program I coded 6 months ago using mmreader (with avi files) does not work properly anymore. It seems like matlab overlaps the video several times. I even tried running the example code (stylophone) given when typing "help mmreader" in the command window, and it appears to be 3 overlapped videos.. Did you find a solution for the problem? Thanks |
