Hi @FidanBacaj :

You can find the default video recorder config here:

Camera/camera/src/main/java/top/defaults/camera/Camera2Photographer.java

Lines 851 to 870 in 6077681

	private void setUpMediaRecorder(MediaRecorderConfigurator configurator) throws IOException {
	if (configurator == null || configurator.useDefaultConfigs()) {
	mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
	mediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
	mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
	mediaRecorder.setOutputFile(nextVideoAbsolutePath);
	mediaRecorder.setVideoEncodingBitRate(10000000);
	mediaRecorder.setVideoFrameRate(30);
	mediaRecorder.setVideoSize(videoSize.getWidth(), videoSize.getHeight());
	mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
	mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
	}
	if (configurator != null) {
	configurator.configure(mediaRecorder);
	}
	mediaRecorder.setOrientationHint(Utils.getOrientation(sensorOrientation, currentDeviceRotation));
	mediaRecorder.prepare();
	}

As you can see, the default video format & codec is:

mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);

So the problem is that the video player your phone provided may not support the H264 codec, so it cannot play the video for you.

There are two ways to solve the issue:

1. Install a video player which support the H264 codec.
2. Configure the video codec by passing in a Photographer.MediaRecorderConfigurator object when you calling Photographer.startRecording(MediaRecorderConfigurator configurator), and set another video codec which your currently using video player supported:

mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263); // for example

You may find these two classes helpful:

• MediaRecorder.OutputFormat
• MediaRecorder.VideoEncoder
