Hardware-Based Mixing &Transcoding with AMD Xilinx
Blog post from Red5
Red5 has collaborated with AMD to integrate low latency hardware-based transcoding and mixing capabilities into Red5 Pro servers by utilizing the AMD Xilinx® Alveo™ U30 media accelerator card. This collaboration enhances Red5 Pro's ability to handle live streaming video by providing high-density real-time transcoding solutions for service providers, OEMs, and CDNs, with support for cloud-based deployments using Amazon EC2 VT1 instances. The integration extends Red5 Pro's architecture by enabling hardware-based transcoding and mixing, with the AMD Xilinx Alveo U30 devices improving the efficiency of video encoding, scaling, and composition. The system supports multiple stream variants via a Transcoder node that handles different bitrates and resolutions, and a Brew-based mixer that combines live streams into a single output stream using hardware acceleration for encoding. This advancement aims to deliver cost-effective, scalable, and high-performance live video streaming solutions, with ongoing evaluations for further optimization involving AMD hardware decoders. Mark Pace, a technology architect with extensive experience in emerging technologies, has contributed significantly to this initiative, leveraging his expertise in software development, large-scale system design, and practical innovation to advance Red5 Pro's capabilities.
