| | 85 | == VMAF video filter == |
| | 86 | |
| | 87 | '''Description:''' Video Multi-Method Assessment Fusion (VMAF) is an metric developed (https://github.com/Netflix/vmaf) by Netflix. The metric provides an indication of how closely a video represents a source/reference. This is semantically similar to PSNR/SSIM, but VMAF is supposed to more closely reflect human visual perception. |
| | 88 | |
| | 89 | '''Expected results:''' Fully function video filter that does not depend on Netflix' code. |
| | 90 | |
| | 91 | '''Prerequisites:''' C coding skills, basic familiarity with git. |
| | 92 | |
| | 93 | '''Qualification Task:''' Create a vmaf video filter based on (and linking to) Netflix' codebase. |

| | 97 | == VP9 decoder improvements == |
| | 98 | |
| | 99 | '''Description:''' Improve FFmpeg's VP9 native decoder. |
| | 100 | |
| | 101 | '''Expected results:''' One or more of the following: |
| | 102 | * AVX2 implementations for all 10/12bpc DSP functions |
| | 103 | * AVX2 implementation for 8bpc loopfilter function |
