VP9 vs H264 vs H265:<p>- Next-gen codecs provide 50% bitrate improvements over x264, but are 10-20x as slow at the top settings required to accomplish such results.<p>- Normalized for CPU usage, libvpx already has some selling points when compared to x264; x265 is still too slow to be useful in most practical scenarios except in very high-end scenarios.<p>- ffvp9 is an incredibly awesome decoder that outperforms all other decoders.<p><a href="https:&#x2F;&#x2F;blogs.gnome.org&#x2F;rbultje&#x2F;2015&#x2F;09&#x2F;28&#x2F;vp9-encodingdecoding-performance-vs-hevch-264&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blogs.gnome.org&#x2F;rbultje&#x2F;2015&#x2F;09&#x2F;28&#x2F;vp9-encodingdecod...</a>
