/**

|

*
|
||||
* The zebrastripe element marks areas of images in a video stream
|
||||
* that are brighter than a threshold with a diagonal zebra stripe
|
||||
* pattern. Typically, this is used to aid in adjusting the exposure
|
||||
* setting on the camera. Setting the threshold to 95 or 100 will
|
||||
* show areas that are completely overexposed and clipping. A
|
||||
* threshold setting of 70 is often used to properly adjust skin
|
||||
* tones.

|

* gst-launch -v videotestsrc ! zebrastripe ! xvimagesink
|
||||
* ]|
|
||||
* Marks overexposed areas of the video with zebra stripes.
|
||||
*
|
||||
* The threshold property is expressed as percentage of full scale,
|
||||
* whereas common usage expresses thresholds in terms of IRE. The
|
||||
* property setting can be calculated from IRE by using the formula
|
||||
* percent = (IRE * 1.075) - 7.5. Note that 100 IRE corresponds to
|
||||
* 100 %, and 70 IRE corresponds to 68 %.
