PyMark

Simple benchmarker Calculates BSQ-rate and BD-rate

Usage

2 modes:

• Benchmark (default) - benchmarks and generates data file (json)
• Plot - reads data file and prints (recommended to use y4m if found desync issues for metric calculations)

-i --input   - input file (could be video or json file )
-e --encoder - encoder to run benchmark for [aom, x265] 
-m --metric  - select which metric to show [VMAF, PSNR, SSIM, MS-SSIM]
-r --rates   - select  which rate modes to calculate [BD, BSQ]
-p --plot    - makes plot for each processed metric

example of usage

Behaviour depends on input, files with .json suffix will be processed in metrics/plot mode, everyting else in benchmark mode

Benchmark 2 encoders from y4m

./pymark.py -i shrek.y4m -e x265 aom data.json will be generated with results of aomenc and x265 encoders

Print metrics

./pymark.py -i data.json -m VMAF PSNR -r BD BSQ will print rates for BD and BSQ, for VMAF and PSNR

VMAF BD rate: -66.2935
VMAF BSQ rate: 0.355
PSNR BD rate: -66.9217
PSNR BSQ rate: 0.35

Plots

adding -p will make plot for each processed metric

Requirements

ffmpeg with libvmaf python Encoders (x265, aomenc)
