Video streaming – motion JPEG

September 8, 2010 | 7:39 pm

Hi everyone,

Is it possible to read an mjpeg video stream using the jit.qt.movie object?
If relevant, my setup is as follow: Logitech QuickCam E3500 connected to a fonera router 2.0n which in turn is connected to my mac via local network.
The fonera web based application uses Cambozola. So what I get is a url (that looks like that http://fonera/luci/;stok=6(…)60/fon_devices/fon_webcam/mjpeg) and a mjpeg stream.

Now, I have tried using the message: read "http://fonera/luci/;stok=6(…)60/fon_devices/fon_webcam/mjpeg" on jit.qt.movie, but without success (in max window it states: read http://fonera/luci/;stok=6(…)60/fon_devices/fon_webcam/mjpeg 0).

I know I don’t have any firewall issues as I managed to make it work with a mpeg4file that is locate on a external ftp site.

I have been looking for this on various forums but couldn’t find any definitive answer.

Any suggestions?

Thanks

hi Eric,

No way to do it with jitter, i’m not sure but I think it’s a quicktime issue.
have a nice day.

You might be able to connect via Java, but it will require some coding. I would suggest googling [java motion jpeg streaming IP camera]. I’m not sure if anyone has already solved this problem and has a Java class for acquiring this stream, but I believe Filippo is correct and that this type of camera is not supported in QT if it doesn’t support an rtsp stream. There might be some third party QT component which supports these cameras, but I’m not aware of one. Again perhaps some other users have solved this problem somehow and can offer advice.

Funny, i was kinda trying the same thing in processing using unprotected ip-camera’s from axis which also broadcast mjpg (still working on it though) It seems you have to use third-party software for this. If i understand correctly it lets you access a video-stream and modify to your needs then make the stream available for further processing in whatever program you like.
