-// VP8 Set Reference Frame
-// =======================
-//
-// This is an example demonstrating how to overwrite the VP8 encoder's
-// internal reference frame. In the sample we set the last frame to the
-// current frame. If this is done at a cut scene it will avoid a keyframe.
-// This technique could be used to bounce between two cameras.
-//
-// Note that the decoder would also have to set the reference frame to the
-// same value on the same frame, or the video will become corrupt.
-//
-// Usage
-// -----
-// This example adds a single argument to the `simple_encoder` example,
-// which specifies the frame number to update the reference frame on.
-// The parameter is parsed as follows:
-//
-//
-// Extra Variables
-// ---------------
-// This example maintains the frame number passed on the command line
-// in the `update_frame_num` variable.
-//
-//
-// Configuration
-// -------------
-//
-// The reference frame is updated on the frame specified on the command
-// line.
-//
-// Observing The Effects
-// ---------------------
-// Use the `simple_encoder` example to encode a sample with a cut scene.
-// Determine the frame number of the cut scene by looking for a generated
-// key-frame (indicated by a 'K'). Supply that frame number as an argument
-// to this example, and observe that no key-frame is generated.
