Set the colour format to be used. Note that this function does not do any conversion. If it returns TRUE then the video device does the colour format in native mode.
<p>
To utilise an internal converter use the <a class="el" href="classPVideoDevice.html#a14">SetColourFormatConverter()</a> function.
<p>
Default behaviour sets the value of the colourFormat variable and then returns TRUE.

This function will set the colour format on the device to one that is compatible with a registered converter, and install that converter so that the correct format is used.
