Applying Quality Encoding Metrics For 2D And VR Video

Description: Choosing the number of streams in an adaptive group and configuring them is usually a subjective, touchy-feely exercise, with no way to really gauge the effectiveness and efficiency of the streams. However, by measuring stream quality with metrics such as CRF, PSNR, Spherical PSNR, Weighted Spherical PSNR, and VMAF, you can assess the quality delivered by each stream and its …
