Crash mjpeg stream from DLINK 930 L

[jaumard]

I tried this library with 3 different stream and camera, works for 2 of them but the third crash :(
It's a D-LINK 930 LB camera, stream works fine from web browser or there Android app but make MjpegSurfaceView crash.

Here is the full log:

Any idea ?

[jaumard]

should be nice to at least catch this exception and show a "no compatible stream" or something

[niqdev]

Hi, is the camera public? there is any way I can reproduce the error? Thanks

[jaumard]

It's not public but I can open it for some time in order to be able to reproduce the crash. Can I have your email to send you the stream link ? To reproduce it's simple just try to read the stream, for me it crash directly without showing any images

[zxc2694]

I also met this problem during using a D-LINK DCS-5020L camera. So sad.

[zxc2694]

@jaumard Could you please share which ipcam can be used fine?

[jaumard]

I test with a PS3 eye on a raspberry pi and a raspberry pi with the official cam module (with mjpg_streamer). I don't have ipcam except the D-LINK.

[niqdev]

Hi, have a look at #35 and #32 and let me know if you have the same error, if it works would be nice to add/wrap another implementation

[jaumard]

I test #32 no error but no stream lol only blank, I try this library with some public mjpeg stream and when it work it take 10 secondes before showing the first frame...
For #35 how can I test this code without building the all library source ? is it possible ?

[niqdev]

Good to know about #32, for #35 I haven't tried the code, but i think the only way for test it would be to download the project, add it to the source, try with the demo app and make a PR if it works.

[vvarock]

Ip camera and mobile connect in same network?

[jaumard]

Yes they are also try on another network too but same problem

[vvarock]

Try on same network but it's showing error

[zxc2694]

Hi, I can use #32 to show public IPCAMs, except my DLINK camera. I don't know what the problem is.
But I find DLINK camera view can be fine displayed on WebView.
It's another method to show ipcam view.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    String myURL = "http://XXXXXXXXX";
    WebView myBrowser=(WebView)findViewById(R.id.mybrowser);

    WebSettings websettings = myBrowser.getSettings();
    websettings.setSupportZoom(true);
    websettings.setBuiltInZoomControls(true);
    websettings.setJavaScriptEnabled(true);

    myBrowser.setWebViewClient(new WebViewClient());

    myBrowser.loadUrl(myURL);
}

[vvarock]

Unfortunately ip cam demo has stopped how to solve this error

[niqdev]

@vvarock your comments are not constructive, unrelated to the issues and not explanatory, you can't spam and add comments everywhere asking for help if you don't explain your problem, provide a sample of the code and a stacktrace

[niqdev]

@zxc2694 Thanks for sharing, is the format of your stream MJPEG? cos this library supports only that format.
I think your solution could be a valid alternative to the unsupported format.
For example in issue #36 there was a similar problem and after spending time debugging the format was mpjpeg which is not supported

[zxc2694]

Yes, my ipcam is also MJPEG streaming, and I think #36 problem is the same as mine.
I don't know how to fix this incompatible problem from this library, so I use another alternative solution.

[niqdev]

Hi @zxc2694 , since @jcRuan had a similar issue, if you solve it, would you like to share what was your alternative solution? Thanks
