Hi Dino,

Almost certainly not. Contact technical support for your camera to see if there is another way to access the video stream.

If you want to try hacking, you might be able to figure out how the java code works by decompiling it. However, you are on your own if you try this.

It would seem that your camera only provides one image per request when you access http://192.168.1.25/image.jpg. When you view this URL in IE or Firefox do you see a video or only one picture? If it is only one picture, my guess is that you need to access another URL in order to get a stream of images. Look in your camera's documentation.

Hi Dino,

To use the camera you need to use an undocumented feature. The reason mmread fails is that it doesn't auto-detect the video format correctly when reading from the camera. To get around this do the following: v = mmread({''http://192.168.1.25/image.jpg','mjpeg'},1:10); This will read 10 frames from your camera as a mjpeg stream.

Best,
Micah

Hi Caglayan,

The second error message is pretty strange. It seems that somehow Matlab is calling the win64 version of mmwrite as if it were win32. I don't know how this could happen. I'll take a look at it in the next few days.

Yes, you are right... if i view http://192.168.1.25/image.jpg in IE i can see only one image. To get stream i have to access http://192.168.1.25/Aview.htm in ActiveX mode or http://192.168.1.25/Jview.htm in Java mode. Is it possible to use these URL in mmread?

Thanks for fast reply,
mmread and mmplay function correctly for any mjpeg video from hard disk, but when i write
v = mmread({'http://192.168.1.25/image.jpg','mjpeg'},1:10);
 mmplay(v);
i can only see the first frame and Matlab answers

Warning: Frame(s) 2 3 4 5 6 7 8 9 10 exceed the number of frames in the
movie.
> In mmread at 189
  In video at 1
Warning: Not all frames specified were captured. Returning what was captured, but
order may be different than specified.
> In mmread at 216
  In video at 1

Thank you for your help in advance.
