[Libav-user] change pixel format without scaling data ?

I am using sws_scale to change the pixel formatting but this routine is also
changing the scale of the data graylevel values themselves and I do not want
it to. Several questions:
* is there a better routine to call to just change pixel format?
* is there a way to turn off data scaling within sws_scale so that it only
changes format?
* which file / what module or subroutine contains the code that actually
measures and rescales the gray values of an image so that i can see exactly
how this is being done ?
