no-rdo: Replace optimized merge routine to decrease bitrate by 1.6%<br>
<br>
In original merge routine, best candidate is selected based on the cost of<br>
encoding with and without residue.<br>
In optimized routine, the best merge candidate is selected based on cost<br>
without residue which increased bitrate by 1.6%.<br>
So replacing optimized routine with original routine to reduce the bitrate<br></blockquote><div><br></div></div><div>What is the performance implication of this? it sounds like a choice that should probably be left in the user's hands.</div>
