React Native (Android) detect sound exists on remote video url












1















I want to create a native android module to detect whether audio tracks exist on a video. Right now I'm using MediaPlayer, but onPrepared isn't being called. Am I missing something? The native module bundles correctly as well. My log says MediaPlayer: Couldn't open file on client side; trying server side: java.io.FileNotFoundException: No content provider: https://storage.googleapis.com/SPECIAL_FILE.mp4



public class RNSoundDetectionModule extends ReactContextBaseJavaModule {

private final ReactApplicationContext reactContext;

public RNSoundDetectionModule(ReactApplicationContext reactContext) {
super(reactContext);
this.reactContext = reactContext;
}
@ReactMethod
public void doesLocalVideoHaveAudioTrack(String path, Callback cb) {
boolean audioTrack =false;

MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource(path);
String hasAudioStr = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_HAS_AUDIO);
if(hasAudioStr!=null && hasAudioStr.equals("yes")){
audioTrack=true; }
else{
audioTrack=false; }
try {
cb.invoke(audioTrack, null);
} catch (Exception e) {
cb.invoke(e.toString(), null);
}
}

@ReactMethod
public void getRemoteAudioTracks(String path, final Callback cb) {
try {
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(path);
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener(){

@Override
public void onPrepared(MediaPlayer mp) {
cb.invoke(mp.getTrackInfo(), null);
}
});
mediaPlayer.prepareAsync();
} catch (IOException e) {
cb.invoke(e.toString(), null);
}
}
@Override
public String getName() {
return "RNSoundDetection";
}
}
