// Generates YUV420 frames with a "landscape with striped crosshair" in the
|
|
// Y-plane, plus a horizontal gradient in the U-plane and a vertical one in the
|
|
// V-plane. This makes for a nice mix of colours that is suited for both
|
|
// catching visual errors and making sure e.g. YUV->RGB/BGR conversion looks
|
|
// the same on different platforms.
|
|
// There is also a solid box bouncing around in the Y-plane, and two differently
|
|
// coloured lines bouncing horizontally and vertically in the U and V plane.
|
|
// This helps illustrating how the frame boundary goes, and can aid as a quite
|
|
// handy visual help for noticing e.g. packet loss if the frames are encoded
|
|
// and sent over the network.
