[android-developers] Re: Playing video in android
Are you looking at the log in DDMS? There must be some log output
associated with your application. At the very least, you should see
ActivityManager starting and stopping it.
You can also add some logging to your code.
import android.util.Log;
private static final String TAG = "MyProgram";
Then scatter log statements around the code in various places:
Log.d(TAG, "This will output to the log");

[android-developers] Re: Playing video in android
> s_filePath = "/data/local/video/test_qcif_200_aac_64.mp4"; This is probably not going to work, since playback is actually handled by a different process, which probably doesn't have permissions to access that file. The preferred way of handling this is to get a FileDescriptor for the file in question, and then using the version of MediaPlayer.setDataSource() that takes a file descriptor. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Playing video in android
First, the surface type needs to be push buffers. In your Preview
constructor, add the following:
getHolder().setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
Second, you need to tell the media player where to display the video.
You have a line commented out:
//mp.setDisplay(mPreview.getHolder().getSurface());
It should look like this:
mp.setDisplay(mPreview.getHolder());
If you get stuck, take a look at the VideoView.java widget source code
on android.git.kernel.org. It's in the frameworks/base project at core/
java/widget/VideoView.java

[android-developers] Re: Playing video in android
Hi
i think you fixed the size of video display
>> mHolder.setFixedSize(176, 144);
it may cause the problem of video displaying
use mHolder.setFixedSize(mp.getVideoWidth(),
mp.getVideoHeight());
