VideoFormat.fromMasks

gstvideo.types.VideoFormat fromMasks(int  depth,  int  bpp,  int  endianness,  uint  redMask,  uint  greenMask,  uint  blueMask,  uint  alphaMask)

Find the #GstVideoFormat for the given parameters.

`depth`	the amount of bits used for a pixel
`bpp`	the amount of bits used to store a pixel. This value is bigger than depth
`endianness`	the endianness of the masks, #G_LITTLE_ENDIAN or #G_BIG_ENDIAN
`redMask`	the red mask
`greenMask`	the green mask
`blueMask`	the blue mask
`alphaMask`	the alpha mask, or 0 if no alpha mask

a #GstVideoFormat or GST_VIDEO_FORMAT_UNKNOWN when the parameters to

not specify a known format.
