Mjpeg Stream Viewing

[GabrielM]

Hi,

ref:- Mjpeg Stream Viewing

I am trying to get/view a Mjpeg video stream from a network camera similar to what you can get if you open the following link in a browser:

"http://83.64.164.6/axis-cgi/mjpg/video.cgi?resolution=320x240"

Found following interesting links where it seems that there are two classes in the package, MjpegInputStream.java and the MjpegView.java that would be needed, so I would like to ask for some help/advice on how to get them in a B4A library:

Links:
Android and MJPEG - Stack Overflow
anddev.org • View topic - MJPEG on Android anyone?

I have tried to get a library done via Eclipse and based on what I could understood from the examples on the forum ref libraries but it would not be that easy for a java noob . I have attached the Eclipse project here:

and the xml+jar files produced and a B4A simple test.

Obviously it fails and as I do not have any java experience at all, only what I have read on this great forum, I've got stuck.

Thank you.

So it seems that it compiles and your created the jar and xml file with no issues.
I will try to test it later. But what is not working? Do you get compilation or run-time errors?

It is the B4A Compilation error like in the attached image

Are you sure it compiled successfully in eclipse?
Looks like your constructors declaration is not correct.

Should this:

public MjpegInputStream(InputStream in) { super(new BufferedInputStream(in, FRAME_MAX_LENGTH)); }

be:

public void MjpegInputStream(InputStream in) { super(new BufferedInputStream(in, FRAME_MAX_LENGTH)); }

I see now the syntax error, you're right. No way to realise this myself and there was no warning on eclipse if I remember right. I will update and try again.

Thank you.

I'm not sure. Eclipse already indicates an error on each line with those red icons on the left side. If you click on them, it also tells you how to resolve them.

VideoView supports streaming: Basic4android - Audio

Have you tried it?

Hi Erel

missed your post...:signOops:

Yes, thank you. I have tried it previously and I got : "Cannot play video
Sorry, this video cannot be played."

What I am trying to do is :
- access the http location of the IP camera;
- provide username and password required;
- play the rtsp stream;

I wish I could wrap the mjpeg viewer java codes as in the first post in this thread into a library.
