Encode MBs until the slice max size is exceeded. Then back up to the<br>
one just before and end the slice.<br>

Jason<br>
<br></blockquote></div>Hello Jason, <br> But what happens if FMO is on? In that case would it mean, that a user defined MB allocation map to make a slice of those MBs is over-ridden by i_slice_max_size?<br>Could it happen that when encoder backs up to the preceeding MB to obey the slice max size limit, and ends the Slice/NAL unit there, and thus does not encode as per the user entered configuration of MB allocation to a slice.<br>
