Inconsistent PSNR and bitrate values with SIMD on and off
What version / commit were you testing with? AVM Research Anchor V2 Commit hash: 007e18e1
What steps will reproduce the problem?
- Compile and run AVM research-v2.0.0 anchor.
- Compile and run AVM research-v2.0.0 anchor with compile time flag: -DAOM_TARGET_CPU=generic
- Results show 0.12% to 0.17% BD-rate difference between the SIMD Enabled and Disabled cases (SIMD case has loss).
- Some screen-content sequences have about 0.4% loss with SIMD enabled.
What is the expected output? The PSNR and bitrate should be the exactly same regardless of SIMD on or off.
What do you see instead? The PSNR and bitrate do not match with differences between SIMD on and off cases.
