Problem reading .mov file

Hi,

I have a sample video in .mov format that I want to import in to MATLAB. I used VideoReader function (the documentation on it says it does support .mov format), but got the following error: Error using VideoReader/init (line 450) File could not be read due to an unexpected error. Reason: No width and height for this File Reason: Unknown error 0xC00D36E6

I also tried mmfileinfo function on the same video, but got the following error: Error using mmfileinfo (line 71) Could not get file information.

Has anyone experienced this before? Does this mean the .mov is missing some header information? My OS is Windows 7.

Any help would be greatly appreciated.

Thanks,

Lin

Does it work with any other mov file? I haven't done that so post your code if you want anyone to try it.

I used videoObj = VideoReader('video_filename.mov').

I just tried two more .mov files that I downloaded from the web. First video gave me the following error:

Error using VideoReader/init (line 450)

Failed to initialize internal resources.

Error in VideoReader (line 147)

obj.init(fileName);

The second sample video I got off from Apple's website, and it worked with no problems.

Was that video created by the same person, organization, or software as the first mov file? Do the failing videos play in QuickTime? Evidently they have something in them that MATLAB's VideoReader doesn't like and you may have to send them the video to figure out what it is.

[lynniz]

Thanks for the information. All three mov files are from different sources, meaning created by different person, organization, and software. I have to try the first video in QuickTime when I get back in the office. Thanks again.

I was able to play the first failing video in QuickTime. I noticed when I looked at the properties of the video, information like frame width, height, and rate are missing. And those were the information missing for the VideoReader as well. I tried couple other .mov files. The ones with frame width, height, and rate information played in QuickTime, WMP, and VideoReader. The ones don't only played in QuickTime. So does this sound like a codec problem?

[Image Analyst]

Sounds like a coder problem - the coder should have put that info in there. QuickTime's decoder is apparently smart enough to able to figure it out for the first failing video, while the others aren't smart enough.

Can you open the *.mov file in Windows Media Player or VLC?

[lynniz]

The initial sample video did not work on Windows Media Player.

[Sean de Wolski]

Then the video is corrupted, non-compliant, or you don't have the right codecs installed on your system.

[lynniz]

So if .mov video works on WMP and maybe QuickTime, then it should also work for VideoReader right? Thanks for your help.

[Sean de Wolski]

If it meets the platform requirements in the documentation then, yes, it should work if WMP or VLC can read it.
