You generally can't use arbitrary dimensions no. What is listed as the possible media types is usually all that is available.

So do I surmise that you video is in a portrait 3x4 configuration or that the image is sideways (90 degree rotation)?

Do you check for any hardware settings? Sometimes there is an option to use the device in landscape mode which may also rotate the camera.
