Iīm trying to capture frames from a video file, but I donīt know how to do it. Are there any classes like FrameGrabbingControl (in JMF) for Android? Is it possible with MediaPlayer and MediaRecorder classes?

I am writing an app to capture the camera preview frames and convert it to bitmap in Android.
Here is my code:...........
After I start preview, the callback got called with data, but the bitmap is null.
What did I do wrong when convert the byte array to BitMap?
Does anyone knows some convinient method to capture video to file or stream from OpenGL app on Android device? For example, can we capture video from a view, opengl view?
I just found out the following:
1) We can get frames using glReadPixels. (No video on this step?)
2) MediaRecorder can encode video, but how can we provide it our raw source, if possible?
3) Any working ports of ffmpeg(for example) or other encoding libraries? There are some tutorials of portng ffmpeg to use withing NDK. So, having raw frames and working port of ffmeg we can create video? Any issues on this step? Anyone managed to port any encoding library successfully? What components do I need from ffpmeg?

Getting frames from Video Image in Android
I wanted to know if it is possible to extract frames from a running Video in Android? I need to extract frames at regular intervals and send them for further processing.
Would someone be able to find an answer for me?
I am trying to decode and obtain all frames in a video stream, each of which would be processed by a native signal processing engine and re-encoded back to a MPEG4/MP4 file. I noticed that there was a getFrameAt() function in earlier versions of SDK but its not available in v 1.6 on which I am working. As I am fairly new to Android, I would like to know from more experienced people around here as to how I can extract video frames into a buffer for processing.

View 2 Replies View RelatedI would like to create a video recorder and so far haven't figured out how to set parameters in order to successfully go through MediaRecorder.prepare() method. Executing the following method
public void start() throws IOException{
String state = android.os.Environment.getExternalStorageState();
if(!state.equals(Environment.MEDIA_MOUNTED))
{
throw new IOException("SD card is not mounted. It is " + state + ".");
}
File directory = new File(path).getParentFile();
if(!directory.exists() && !directory.mkdirs())

throw new IOException("Path to file could not be created.");

recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
recorder.setVideoFrameRate(15);
recorder.setVideoSize(176, 144);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
this.state = VideoRecorderState.STATE_RECORDING;
}
it throws an exception on line recorder.prepare(). Does anyone know how to set parameters in order to be able to capture video?
I would like to be able to capture the video from an android phone camera, and then process this video. Processing involves adding a layer of AR to the live stream. Is this possible on android? Pretty sure it should be. I have looked at the android site [http://developer.android.com/guide/topics/media/index.html] but this seems to be concerned with video capture and storage. I would like to be able to play with the video pre-storage.

View 1 Replies View RelatedOne of the alternative app stores is asking for unaltered, unedited capture from the app as a video. Plus I'm also interested in cleaner video than I get by focusing a camcorder on an Android on a table. Who knows how to do that? I think I found some posts that indicate Mark Murphy may have solved this with a tool that goes through DDMS. If so, I'll get that tool and donate.

View 2 Replies View RelatedI was wondering if anyone knows of a tutorial explaining how to capture the video from the camera on an Android device and then display the video in real time on the screen? I have looked up MediaRecorder, MediaPlayer, Videoview but they all seem concerned with recording audio/video to a file or playing audio/video from a file or a URL. I simply want to be able to take the data from what the camera is seeing and display it on the screen.

View 1 Replies View RelatedI need to make a video as a DEMO for one application I have developed. I know that there are some experimental applications that use DDMS and achieve a framerate of 5-6 fps. This framerate is completely insufficient for my purposes since the application has smooth animations that i would like to show. Is there anyone that has found a way to do a real time screen capture on android? Should I settle for a capture of the emulator or a real video done with a real camera?

It happens that I press the trackball and the timer (on the upper-right corner) disappears and nothing works anymore (menu, etc...), only the Home button allow me to go back to the home panel. After doing that, the battery die in a few minutes and the phone is very slow: i.e. some video camera service is still up and running and consuming battery.

(see http://stackoverflow.com/questions/809878/android-how-do-a-display-a-large-animated-gif-given-a-url).
It's anything but smooth. On Android 1.5, the Movie.decodeStream()/decodeFile() returns a null. On Android 1.6, with the GIF files I've got, it returns a zero-sized movie with zero duration - clearly not adequate.
The referenced question suggests splitting the GIF into frames (and then rendering these). How exactly do i accomplish that, please? Tried opening one of my GIFs with GNU giflib in Windows. It choked on the very first frame. The GIF itself is all right, all browsers (save Android's) display and animate it fine. Worked with giflib 4.1.4. Not sure what was broken in 4.1.6, but there you go. Next step: build giflib for Android via NDK, somehow integrate with the Bitmap class. giflib it is. In conjuction with Bitmap.copyPixelsFromBuffer. The colors are all askew right now, but the basic design seems workable.
