Method Detail

choosePreviewSize

public static void choosePreviewSize(android.hardware.Camera.Parameters parms,
                     int width,
                     int height)

Attempts to find a preview size that matches the provided width and height (which specify the dimensions of the encoded video). If it fails to find a match it just uses the default preview size for video.

TODO: should do a best-fit match, e.g. https://github.com/commonsguy/cwac-camera/blob/master/camera/src/com/commonsware/cwac/camera/CameraUtils.java

chooseFixedPreviewFps

public static int chooseFixedPreviewFps(android.hardware.Camera.Parameters parms,
                        int desiredThousandFps)

Attempts to find a fixed preview frame rate that matches the desired frame rate.

It doesn't seem like there's a great deal of flexibility here.
