-// AV1 Set Reference Frame
-// ============================
-//
-// This is an example demonstrating how to overwrite the AV1 encoder's
-// internal reference frame. In the sample we set the last frame to the
-// current frame. This technique could be used to bounce between two cameras.
-//
-// The decoder would also have to set the reference frame to the same value
-// on the same frame, or the video will become corrupt. The 'test_decode'
-// variable is set to 1 in this example that tests if the encoder and decoder
-// results are matching.
-//
-// Usage
-// -----
-// This example encodes a raw video. And the last argument passed in specifies
-// the frame number to update the reference frame on. For example, run
-// examples/aom_cx_set_ref av1 352 288 in.yuv out.ivf 4 30
-// 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
-// ---------------------
-// The encoder and decoder results should be matching when the same reference
-// frame setting operation is done in both encoder and decoder. Otherwise,
-// the encoder/decoder mismatch would be seen.
