US, did you make it??

You managed to use your own file at the demo???

Please tell us :) :)

By the way, I contacted the technical support...!!

Hi,

If you replace the BinaryFileReader with MultimediaFileReader:

http://www.mathworks.com/access/helpdesk/help/toolbox/vipblks/ref/video.multimediafilereaderclass.html

you will be able to read in other video types.

The MultimediaFileReader can handle many formats (including compressed AVIs) on Windows but only
uncompressed AVIs on Unix. The binary file viptraffic.bin is supported across all platforms,
and that's why it was used for this demo.

Thank you very much Witek.

I used it but in the final steps of the code there was an error, which forces Matlab to restart...

I do not know why...

Thank you so much for your help...

I do not know how to use my own .avi video yet....

Hi Chris,

If you can post the error, maybe we can help you. If you are not seeing an error and instead MATLAB exits,
consider running it with -logfile switch:

matlab -logfile my_favorite_file_name.txt

and then looking into the file for errors.

I hope that you were able to incorporate your AVI file into the demo. In terms of mechanics of reading
the file in, a good start is the example that comes with the MultimediaFileReader object:

% EXAMPLE: Read a video and play it.
hmfr = video.MultimediaFileReader('viplanedeparture.avi');
hp = video.VideoPlayer;
while ~isDone(hmfr)
videoFrame = step(hmfr);
step(hp, videoFrame);
end
release(hp);
release(hmfr);

HTH,

Witek

Thank you very much Witek!! :)

I believe the problem is that I cannot even read and play my own video..I tried your example ( Read a video and play it), with my own .avi file in the workspace that I have chosen, eg :

C:\Program Files\MATLAB\R2010a\toolbox\vipblks\vipdemos
(where there are all the example videos!!)

but I get the following error :

MATLAB crash file:C:\Users\Chris\AppData\Local\Temp\matlab_crash_dump.4004:

If this problem is reproducible, please submit a Service Request via:

A technical support engineer might contact you with further information.

Thank you for your help. MATLAB may attempt to recover, but even if recovery appears successful,
we recommend that you save your workspace and restart MATLAB as soon as possible.

Then I choose "Attempt to continue" and I get the above error along with :
Caught MathWorks::System::FatalException
[Please exit and restart MATLAB]>>

Thank you sooo much :) :)
You have been really helpful :) :)
