The audio play but the images do not move

[vsoftphuong]

After exporting to mp4, you open mp4 file in File Explorer : the audio plays but the images do not move, after a period of time the audio stops playing and the picture starts to move. Display time is also not normal (video about 10s but time show about >2h).

Code:
AnncaConfiguration.Builder builder = new AnncaConfiguration.Builder (context, CAPTURE_MEDIA);
builder.setMediaQuality (AnncaConfiguration.MEDIA_QUALITY_LOW);
builder.setMediaResultBehaviour (AnncaConfiguration.PREVIEW);
builder.setVideoDuration (2 * 60 * 1000);
new Annca (builder.build ()) launchCamera ();

Thanks!
