For HEVC, we evaluated Intel’s SVT (Scalable Video Technology)-HEVC, a software-based codec that purports to deliver hardware-like performance NGCodec’s FPGA-based HEVC encoder and x265 using the medium and veryfast presets. For perspective, we also included FFmpeg’s x264 codec using both the medium (default) and veryfast settings. For H.264, we compare the NVIDIA H.264 and Intel Quick Sync codecs, analyzing performance and output quality for live transcoding applications. This article analyzes several hardware-based transcoding solutions. In this schema, you send a single efficient stream to the cloud, transcode the stream to produce a complete encoding ladder, package as necessary, and deliver the streams to the origin server or CDN. Live transcoding on the web has quickly evolved into the optimal workflow for streaming live events.
