I am having trouble with my main app crashing after a few minutes of streaming to my cloud RTMP server. The app crash is attached at bottom of this post.
A little background - the code is for a dji mini 3 running on a samsung galaxy S22 using the sample app from sdk 5.1.7 derived from
Here is the code on the main app that runs on a fragment (the home fragment) and is performed onCreateView
// note this is a listener and when the stream source is updated it gets called
MediaDataCenter.getInstance().getVideoStreamManager().addStreamSourcesListener
(sources -> getActivity().runOnUiThread(() -> updateFPVWidgetSource(sources)));
primaryFpvWidget.setOnFPVStreamSourceListener((devicePosition, lensType) -> {
cameraSourceProcessor.onNext(new HomeFragment.CameraSource(devicePosition, lensType));
});
IVideoChannel primaryChannel =
MediaDataCenter.getInstance().getVideoStreamManager().getAvailableVideoChannel(VideoChannelType.PRIMARY_STREAM_CHANNEL); if (primaryChannel != null) {
primaryChannelStateListener = (from, to) -> {
StreamSource primaryStreamSource = primaryChannel.getStreamSource();
if (VideoChannelState.ON == to && primaryStreamSource != null) {
getActivity().runOnUiThread(() -> primaryFpvWidget.updateVideoSource(primaryStreamSource, VideoChannelType.PRIMARY_STREAM_CHANNEL));
}
};
primaryChannel.addVideoChannelStateChangeListener(primaryChannelStateListener);
After product connect, in a separate worker thread after on product connect, I start the stream like this:
ILiveStreamManager liveStreamManager = MediaDataCenter.getInstance().getLiveStreamManager();
LiveStreamSettings.Builder lssBuilder = new LiveStreamSettings.Builder();
RtmpSettings.Builder b = new RtmpSettings.Builder();
b.setUrl(liveURL);
RtmpSettings rtmp = b.build();
lssBuilder.setRtmpSettings(rtmp);
lssBuilder.setLiveStreamType(LiveStreamType.RTMP);
LiveStreamSettings lss = lssBuilder.build();
liveStreamManager.setLiveStreamSettings(lss);
// the video going to app display is primary - MUST BE PRIMARY!!! or dont see video
liveStreamManager.setVideoChannelType(VideoChannelType.PRIMARY_STREAM_CHANNEL);
liveStreamManager.setLiveStreamQuality(StreamQuality.SD); // make quality lower?
//liveStreamManager.setLiveVideoBitrate(2048); // small
liveStreamManager.setLiveVideoBitrateMode(LiveVideoBitrateMode.AUTO);
liveStreamManager.startStream(new CommonCallbacks.CompletionCallback() {...}
What am I doing wrong?

i'm also having issues with msdk v5 sample & RTMP. i saw that in the testing tools section the rtmp works well, maybe there is a way to call the methods in there ?
