/**
  * 14.8 smptehdbars
  * The allrgb source returns frames of size 4096x4096 of all rgb colors.
  *
  * The allyuv source returns frames of size 4096x4096 of all yuv colors.
  *
  * The color source provides an uniformly colored input.
  *
  * The haldclutsrc source provides an identity Hald CLUT. See also
  * haldclut filter.
  *
  * The nullsrc source returns unprocessed video frames. It is mainly useful to be employed in analysis / debugging tools, or as the source for filters which ignore the input data.
  *
  * The pal75bars source generates a color bars pattern, based on EBU PAL recommendations with 75% color levels.
  *
  * The pal100bars source generates a color bars pattern, based on EBU PAL recommendations with 100% color levels.
  *
  * The rgbtestsrc source generates an RGB test pattern useful for detecting RGB vs BGR issues. You should see a red, green and blue stripe from top to bottom.
  *
  * The smptebars source generates a color bars pattern, based on the SMPTE Engineering Guideline EG 1-1990.
  *
  * The smptehdbars source generates a color bars pattern, based on the SMPTE RP 219-2002.
  *
  * The testsrc source generates a test video pattern, showing a color pattern, a scrolling gradient and a timestamp. This is mainly intended for testing purposes.
  *
  * The testsrc2 source is similar to testsrc, but supports more pixel formats instead of just rgb24. This allows using it as an input for other tests without requiring a format conversion.
  *
  * The yuvtestsrc source generates an YUV test pattern. You should see a y, cb and cr stripe from top to bottom.
  *
  * The sources accept the following parameters:
