Your ticket doesn't seem very clear what you are actually asking for?
vf_zscale supports conversion between pixel formats, which includes conversion from YCbCr to RGB, as well as changing bitdepth as required. There is no specific "bitdepth" option, because the bitdepth in ffmpeg is controlled/implied through the pixel format you ask to convert to.
