Description
This module performs measurements on video encoding and decoding. It also provides a detailed dataset.
It manages the following parameters:
It supports the libx264, libx265, libvpx-vp9, libsvtav1 and vvc encoders.
Distortions are measured using the lpips, psnr, ssim and vmaf metrics.
Encoding efforts are fast, medium and slow.
It takes care about the colorspaces.
Iterate over different effort, encoder, quality, threads, fps, resolution and pix_fmt.
Energy measurements are catched with RAPL and an external wattmeter on grid'5000.
Get the cpu and ram activity.
Get a full environment context, including harware and software version.
Pipeline
This is the pipeline used for measurements:
Example of result
Example of rate distortion curve:
mendevi plot mendevi.db -x bitrate -y psnr -y ssim -wx profile -c encoder
Alternatives
The MVCD database also includes video encoding and decoding energy measurements.
The COCONUT database also includes video decoding measurements.
