and it has proven efficient and stable in live streaming tests with FFmpeg integration. Optimizer readily integrates into any streaming workflow through a simple API call before or in parallel with the encoder (Figure 1).
Enhancing video efficiency and quality
VisualOn Optimizer is tightly embedded within the FFmpeg ecosystem. It can be readily integrated with a video encoder through FFmpeg’s APIs, regardless of the video compression format or whether the encoder is CPU-based or GPU-based. Additionally, it has been integrated with Intel® Quick Sync Video in Intel® Core™ processors for AVC, HEVC, and AV1 transcoding.

Reduced bitrates
Extensive benchmark results, as well as actual production deployments, reveal how Optimizer significantly reduces the average video bitrate. Figure 2 illustrates one such test compared to FFmpeg based on VisualOn’s testing. 9 Bit rate reduction leads to improved operational efficiency by reducing bandwidth requirements and delivery and storage costs, plus it helps lower energy consumption.
