Hi Harish,
I think the video view widget am using is by default available inside
android.
It uses the Camera.apk internally having the movie view.
And thanks for the inputs on my query.
As said in my previous mail, for a VGA(640X480) display panel the resize is
not happening for the cases 2 and 3 mentioned.
Specifically,
2. QVGA(320X240) QVGA(320X240)=> (No resize)
3. 160x120 160x120 => (No
resize)
Otherwise for other i/p stream resolutions the resize is happening.
So, as per your suggestion, if i use the following code. Please correct if
the notation for width and height fixed values is like "640px" and "480px"?
Will this change does resize to full screen(VGA) of cases 2 and 3 as well?
I suppose this change will affect the camera.apk alone.
<VideoView
android:id="@+id/surface_view"
android:layout_width="640px" -> can be replaced to any
desried width
android:layout_height="480px" -> can be replaced to any
desired height
android:layout_centerInParent="true"
/>
Regards,
Sreedhar
