VideoView on top of SurfaceView

阅读更多关于 VideoView on top of SurfaceView

问题 I try to show a VideoView on top of a SurfaceView . But it isn't visible but reacts on clicks (MediaController appears and the sound plays). The video seems to be played behind the SurfaceView so I also tried to make use of setZOrderMediaOverlay() and/or setZOrderOnTop() but nothing changed When I go to the home screen I see the VideoView for a split second in the fading animation, so it is really there. I tried it with a xml layout and also completely programmatically but nothing works. Here

How to capture/record clip from Video URL in Android and save to phone

阅读更多关于 How to capture/record clip from Video URL in Android and save to phone

问题 In Android, is it possible to record a short clip (ex: an arbitrary 5-10 seconds in the video) from a Video URL (ex: http://www.test.com/video.mp4)? For example, I'd like to stream a video (from url) in an Activity and allow the ability to capture/record a short clip from it. Perhaps, allow the user to record an arbitrary Start/End time from the video. If so, is there an API to accomplish this? If not, is there an Android library to support this? Please provide a sample code solution for this

Somewhere in my Android app I would like to play a youtube video, in my activity, in a small view. I'm trying to do this using VideoView , but no luck so far.. I wrote a simple activity, here is my code so far: public class MainView extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); VideoView videoView = (VideoView) findViewById(R.id.VideoView); MediaController mediaController = new MediaController(this); mediaController.setAnchorView(videoView); /*working good but IT'S NOT youtube*/ //Uri video =

Detect if a VideoVIew is buffering

阅读更多关于 Detect if a VideoVIew is buffering

问题 Does anyone know if it's possible to detect when a VideoView is buffering? I want to show a ProgressDialog when the video is buffering. So far I tried using a OnPreparedListener, but that only works when the video is first loaded. If a video is playing and the user moves the scrub bar to a different point the video is still "prepared" even though it is buffering. I also tried (I know this is awful) an AsyncThread that just busy waits on isPlaying(): private class BufferTask extends AsyncTask

How to capture screenshot or video frame of VideoView in Android

阅读更多关于 How to capture screenshot or video frame of VideoView in Android

I've tried the following tutorial from this blog ( http://android-er.blogspot.kr/2013/05/get-current-frame-in-videoview-using.html ), which shows how to capture a video frame using MediaMetadataRetriever from a video source. However , it only works if the video is located locally on the phone. Is there a way to capture a video frame while the VideoView is streaming the video over IP? I have found a solution to this problem. It appears that the VideoView does not allow this because of low-level hardware GPU reasons while using a SurfaceView. The solution is to use a TextureView and use a

问题 Does android native "VideoView" video rendering widget plays encrypted video files? And if yes then how to play it and what all the APIs. I have gone through this link i don't find anything related playing encrypted video. Is it that i need to decrypt my video and then pass it to VideoView? 回答1: VideoView can't play an encrypted video, you have to decrypt it yourself. There are roughly two ways: generate a temporary clear file from the encrypted one, but this has some inconveniences: a delay

Editing android VideoView frames

阅读更多关于 Editing android VideoView frames

Environment: Nexus 7 Jelly Bean 4.1.2 Problem: I'm trying to make a Motion Detection application that works with RTSP using VideoView. I wish that there was something like an onNewFrameListener videoView.onNewFrame(Frame frame) I've tried to get access to the raw frames of an RTSP stream via VideoView but couldn't find any support for that in the Android SDK. I found out that VideoView encapsulates the Android's MediaPlayer class. So i dived into the media_jni lib to try and find a way to access the raw frames, But couldn't find the byte buffer or whatever that represents a frame. Question:
