This talk presents the implementation of a video encoder analysis within GStreamer. We'll demonstrate our video-encoder-stats element that collects real-time encoding performance metrics including bitrate, processing time, CPU usage, and VMAF quality scores, attaching this data as metadata to video buffers throughout the pipeline. The presentation covers our video-compare-mixer element that enables side-by-side visual comparison of multiple encoder outputs with interactive navigation controls, supporting various backends. We'll showcase how these elements work together in our demo tool. https://github.com/fluendo/gst-plugins-rs/pull/4
