Why code for capturing video is not working in one plus?

I used video capturing code using built-in camera in an application, but it reporting issues some of android phones like OnePlus phones. in other phones it works perfectly, can anyone help me to solve this issue, i tried many times but it didn't work, I'm sharing my code below..
Acutually it is shows only in device like one plus, I try to use built-in cam for to recording video, in my project, After we click button for to record video, it will redirected to the built-in cam in the device, in other devices it's working perfectly. but in one plus version11 , after we click the button for to record video it will not redirected to built-in cam, it is just stuck with the same page.. this is the issue
private void captureVideo() {
Intent VideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
if (VideoIntent.resolveActivity(getPackageManager()) != null) {
VideoIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
VideoIntent.putExtra("android.intent.extras.CAMERA_FACING", 1);
VideoIntent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 3);
VideoIntent.putExtra(MediaStore.EXTRA_FINISH_ON_COMPLETION,true);
startActivityForResult(VideoIntent, VIDEO_REQUEST);
}
}

Parsing logcat output on android phone [duplicate]

I want to get MediaMetadata (song title / artist) from the current playing android audio source for any app (spotify, google play, soundcloud, YouTube, blackplayer, etc) and am trying to use MediaMetadataRetriever.setDatSource
Currently I have a function 'getActiveNotifications' in 'MainActivity.java' that gets called whenever a button is pressed, my code looks like this:
public void getActiveNotifications(View view) {
String temp ="temp";
Log.i("myTag", "Logging active notifications:");
//get data from MediaMetaData somehow? Always displays correct string in Logcat
MediaMetadataRetriever mmr = new MediaMetadataRetriever();
//mmr.setDataSource("CURRENT APP PLAYING MUSIC (googlePlay / Spotify / Soundcloud etc)");
mmr.setDataSource("https://somewebsite.com/somefile.mp3", new HashMap<String,String>());
//extract metadata and save to string
String albumName = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_TITLE);
Log.i("myTag", "done with function. ");
}
Can I use .setDatSource generally for any music app or does it work for files only?
I can see updateMediaMetaData in Logcat printing media metadata of the currently playing song working for both music streaming and file playing apps (see pic)
Am I on the correct track here? Is there a way I can use .getDataSource on streaming / fileplayer apps for whatever the currently playing audio source is?
any help much appreciated, thanks

codename one mediaplayer not working on android device

i am creating a mediaplayer app which is supposed to stream mp3 files from remote url.the problem is that the everything works fine on the codename one simulator but not on an actual android device.I want the app to show native player controls like on the simulator.below is my code and screenshots
try {
video = MediaManager.createMedia(sample_url,true);
Display.getInstance().callSerially(() -> {
if (mp != null){
mp.getMedia().cleanup();
}
Image samp = theme.getImage("sample.png");
Label samlabel = new Label();
samlabel.setIcon(samp);
mp = new MediaPlayer(video);
mp.setAutoplay(false);
video.setNativePlayerMode(true);
sample.add(BorderLayout.CENTER,BorderLayout.centerAbsolute(samlabel));
sample.add(BorderLayout.SOUTH,mp);
//songDetails.add(mp);
});
the first image is the simulator screenshot and the second image is the actual android device screenshot

It's unclear from your post if this is an mp3 which is audio and doesn't have media control or an actual video. The MediaPlayer class is strictly for video and you passed true to indicate that this is a video file so I'll treat it as such.
Notice that if this is an audio file then you need to add/create your own controls and shouldn't use the MediaPlayer class.
We recently defined behaviors for native media control rendering as explained here.
Just use:
video.setVariable(Media.VARIABLE_NATIVE_CONTRLOLS_EMBEDDED, true);

LibVLC fails to show subtitles for streamed video

I tried to create a video player on android device, which could stream videos from local server. I found an this example. I followed to the guideline and at the end I was able to play local video on my device. Then I started to modify this project. I set VideoActivity as launcher activity and commented out all data received from previous activity. I modified initialization of media from
Media m = new Media(libvlc, media);
mMediaPlayer.setMedia(m);
to
Uri uri = Uri.parse("http://samples.mplayerhq.hu/MPEG-4/embedded_subs/1Video_2Audio_2SUBs_timed_text_streams_.mp4");
Media m = new Media(libvlc, uri);
mMediaPlayer.setMedia(m);
Added 2 new methods (as you see, those methods are dummy methods simply to see the result)
private void setSubtitles(){
MediaPlayer.TrackDescription[] tds = mMediaPlayer.getSpuTracks();
mMediaPlayer.setSpuTrack(tds[tds.length - 1].id);
}
private void seekTo(long time) {
mMediaPlayer.setTime(time);
}
And called them on play event
#Override
public void onEvent(MediaPlayer.Event event) {
VideoActivity player = mOwner.get();
switch(event.type) {
case MediaPlayer.Event.EndReached:
Log.d(TAG, "MediaPlayerEndReached");
player.releasePlayer();
break;
case MediaPlayer.Event.Playing:
---> player.seekTo(1000);
---> player.setSubtitles();
case MediaPlayer.Event.Paused:
case MediaPlayer.Event.Stopped:
default:
break;
}
}
But when ever I tried to play the video, I got 12401-12591/? A/libc﹕ ### ABORTING: INVALID HEAP ADDRESS IN dlfree. I get this error some seconds after subtitles ar shown (Also subtitles are too small). This error is shown only when I try to show subtitles. Without subtitles video is playing without any error.
I tried to play this video on VLC application and it was able to show subtitles. I tried to create new project - got the same error. I analysed VLC android source code and it looks that they are using almost the same logic for loading subtitles (Only setting different surfaceViews for video and subtitles, but it gave me the same error). So what am I missing? What does cause player to brake and how to fix it? Maybe there is already working example of code for showing subtitles.

How to get supported video camera resolutions in android?

I am writing an app where I am allowing the user to capture video using the phones camera. I am using my own code to record the video as opposed to Androids built in camera app.
Everything is working OK except I need to be able to access the list of supported camera resolutions so I can choose at runtime which one to use. I am looking for something like getSupportedPictureSizes() but for video. Android 3.0 has this functionality but I am looking for something for 2.2.
As of right now I am using CamcorderProfile.QUALITY_HIGH / QUALITY_LOW, but this only gives me two options and on the phones I have been testing on, the file sizes are at each extreme.(QUALITY_LOW is 216 kb/s and QUALITY_HIGH is > 3 MB/s)
Any help would be greatly appreciated,
Thank You!

Did you try to use the getSupportedVideoSizes() method from Camera.Parameters class?
public List<Camera.Size> getSupportedVideoSizes()
This method returns a list of Size objects. It will return null if the camera does not have separate preview and video output. The answer here indicates that when this returns null you may use the getSupportedPreviewSizes() list.

Ok I think I figured it out. It seems to work correctly on the phones I have been testing on.
List<Size> tmpList = camera.getParameters().getSupportedPreviewSizes();
final List<Size> sizeList = new Vector<Size>();
//compair the apsect ratio of the candidate sizes against the real ratio
Double aspectRatio = (Double.valueOf(getWindowManager().getDefaultDisplay().getHeight()) / getWindowManager().getDefaultDisplay().getWidth());
for(int i=0; i<tmpList.size(); i++){
Double tmpRatio = Double.valueOf(tmpList.get(i).height) / tmpList.get(i).width;
if(Math.abs(aspectRatio - tmpRatio) < .15){
sizeList.add(tmpList.get(i));
}
}
