Also i have check when i did comment below code
Mjpeg.newInstance().open("myurl/?action=stream", 5) .subscribe(inputStream -> { holder.videoView.setSource(inputStream); holder.videoView.setDisplayMode(displayMode); holder.videoView.showFps(false); }, throwable -> { Log.e(TAG, "mjpeg error " + throwable.getMessage()); });
I did not get any error as above mention

Thanks
Did you try to debug with the emulator or the phone to check which line is causing the issue? Can you confirm that is a valid mjpeg stream? Thanks
