if color converter component is not selected then sink component will not work, even if specified
output file name check
getting video source handle
getting color converter component handle, if specified
getting sink component handle - if reqd'
output buffer size calculation based on input dimension speculation
if tunneling option is given then set up the tunnel between the components
sending command to video source component to go to idle state
in tunnel case, change the color conv and sink comp state to idle
if tunneling option is not given then allocate buffers on video source output port
in non tunneled case, using buffers in color conv input port, allocated by video dec component output port
allocating buffers in the color converter compoennt output port
send command to change color onv and sink comp in executing state
sending command to video source component to go to executing state
state change of all components from executing to idle
sending command to all components to go to loaded state
freeing buffers of color conv and sink component
freeing buffers of video source input ports
closing the output file

this function sets the color converter and video sink port characteristics based on the video source output port settings
setting the color converter and sink component chararacteristics, if selected - both in tunneled as well as non tunneled case
setting the color conv input port width, height it will be same as the video source output port width, height
setting the color converter output width height it will be same as input dimensions
setting the input color format of color converter component it will be same as output yuv color format of the source component
setting output RGB color format of the color converter component
if video sink component is selected then set its input port settings accroding to the output port settings of the color converter component
