I'm using the following snippet within a class's onCreate that
extends ImageView
MediaMetadataRetriever retrieve = new
MediaMetadataRetriever();
retrieve.setDataSource(name);
long Duration =
Long.parseLong(retrieve.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION));
for (int frame = 0; frame < Duration; frame += 300) {
parent.removeAllViews();
Bitmap pict = retrieve.getFrameAtTime(frame);
Log.e("Media" , "Video Loading " + frame);
Matrix matrix = new Matrix();
float scale = 680.0f / pict.getHeight();
matrix.postScale(scale, scale);
Bitmap image = Bitmap.createBitmap(pict, 0, 0,
pict.getWidth(), pict.getHeight(), matrix, true);
layers[1] = new BitmapDrawable(mBitmap);
layers[1].setAlpha(255);
layers[0] = new BitmapDrawable(image);
layers[0].setAlpha(255);
LayerDrawable layerDraw = new LayerDrawable(layers);
super.setImageDrawable(layerDraw);
parent.setBackgroundColor(Color.BLACK);
parent.addView(this , new
LayoutParams(LayoutParams.FILL_PARENT , LayoutParams.FILL_PARENT));
}
Log.e("Media" , "Video LoadED ");
What I can't understand is that is runs through the loop fine, but it
only shows the first frame ?
parent is the FrameLayout within which the ImageView is to be shown .
Can anyone shed light on this
Thanks in advance ?
