Comment(by Quozl):

 Cheese uses "videoflip method=4" for horizontal flip effect.  It does not
 appear to use the kernel API for telling the camera to flip the image,
 since ''videoflip'' is a processing step in the chain.  gstvideoflip.c
 contains transformations of the pixel data to implement the effect.  The
 processing impact could be significant.  This should be reasonably easy to
 test in Record ... to see what impact it has on frame rate.

 For the ''v4l2src'', there isn't an obvious way to flip the image, but
 there is a ''device-fd'' property that might be used to send the
 appropriate settings to the camera.

 There's also a GstVideoOrientation thing, but I've not yet figured it out.
 I was wondering if there was a way to specify the orientation immediately
 after v4l2src, on the "video/x-raw-yuv" code, but ran out of time.
