what is association between qf (quality factor) and trate (target bit rate)?
both are data members of dirac_encparams_t.
if i want to set my bit rate 256kbps ,then what is the significance of quality factor ?
how are they related to each other?
Thanks in advance .
QF is used in constant quality mode and trate is used in constant bitrate mode. When trate is non-zero it overrides QF. In constant bit-rate mode the value of QF is used to set the initial quality only. Having a high QF in CBR mode can result in the encoder taking longer to adapt to the required constant bit rate.
