This adds some extra options that affect pattern=ball mode, allowing the animation to be synced to running time or wall-time clock for comparing sync across different instances / pipelines / machines. Also added is the ability to invert the rendering colours every second, and some different ball motion patterns. https://bugzilla.gnome.org/show_bug.cgi?id=740557

|
|
*
|
|
* The Gamut pattern creates a checkerboard pattern of colors at the
|
|
* edge of the YCbCr gamut and nearby colors that are out of gamut.
|
|
* The pattern is divided into 4 regions: black, white, red, and blue.
|
|
* After conversion to RGB, the out-of-gamut colors should be converted
|
|
* to the same value as their in-gamut neighbors. If the checkerboard
|
|
* pattern is still visible after conversion, this indicates a faulty
|
|
* conversion. Image manipulation, such as adjusting contrast or
|
|
* brightness, can also cause the pattern to be visible.
|
|
*
|
|
* The Zone Plate pattern is based on BBC R&D Report 1978/23, and can
|
|
* be used to test spatial frequency response of a system. This
|
|
* pattern generator is controlled by the xoffset and yoffset parameters
|
|
* and also by all the parameters starting with 'k'. The default
|
|
* parameters produce a grey pattern. Try 'videotestsrc
|
|
* pattern=zone-plate kx2=20 ky2=20 kt=1' to produce something
|
|
* interesting.
