Provides good visual quality gains at the highest quality presets. </li><li>rc-grain: Enables a new ratecontrol mode specifically for grainy content. Strictly prevents QP oscillations within and between frames to avoid grain fluctuations.</li><li>tune grain: A fully refactored and improved option to encode film grain content including QP control as well as analysis options.</li><li>asm: ARM assembly is now enabled by default, native or cross compiled builds supported on armv6 and later systems.</li></ul></div><div>==================================== API and Key Behaviour Changes ==================================<br></div><div><ul><li>x265_rc_stats added to x265_picture, containing all RC decision points for that frame</li><li>PTL: high tier is now allowed by default, chosen only if necessary</li><li>multi-pass: First pass now uses slow-firstpass by default, enabling better RC decisions in future passes </li><li>pools: fix behaviour on multi-socketed Windows systems, provide more flexibility in determining thread and pool counts</li><li>ABR: improve bits allocation in the first few frames, abr reset, vbv and cutree improved</li></ul></div><div>=============================================== Misc ==============================================</div><div><ul><li><span style="font-size:12.8px">An SSIM calculation bug was corrected</span></li></ul></div><div><br></div><div>Thanks, <br></div><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div>Deepthi Nandakumar<br></div>Engineering Manager, x265<br></div>Multicoreware, Inc<br></div></div>
