20 Aug 2010 mmwrite write AVI/ASF/WMV/WMA file from movies read by mmread Author: Micah Richert

Hi Peng,

The audio and video quality parameters only apply to WMV files. To change the quality for AVI files you have to do this manually through ffdshow config.

I hope that helps,
Micah

Hi Vineet,

Email me directly. How many times do you have to call mmread before it starts having problems? I have done stress tests and run it 10,000 times in a row without a problem.

Are you using useFFGRAB==false? If this is the case, then that can explain your memory leak. A lot of Direct Show filters have memory leaks; none of which I have any control over. And the only way to free the memory is to quit Matlab.

Also, you may consider using processFrame.m instead of calling mmread many times. This may not work for your purposes though...

Best,
Micah

Hi Tobias,

1. No one else has ever reported your issue before. Have you run "ls" or "dir" from Matlab's command prompt and confirmed that Matlab also thinks that your video is in the current directory?

2. Sorry, mmwrite only works on Windows. I have considered writing a multi-OS version but it would be a complete rewrite.

Best,
Micah

Hi Arash,

You shouldn't have to recreate the mex file. Not to mention it is a huge pain to try to compile the mex files yourself, so I don't recommend it.

What is the problem you are having?

Best,
Micah

Hi,Micah,
Thanks for your work on writing video files using Matlab.
I have tried mmwrite on my machine,but when I use mmwrite to write back an AVI file , I can't change video & audio quality .The output file has no differences between differentvideo & audio quality config.
I already have 'ffdshow' ,and test other encoders.
What a problem can it be?
Thanks.

Thanks very much! Being able to read in frames from wmv's and mov's on a linux machine has improved my quality of life : )
