The Wowza Streaming Engine™ media server software Transcoder supports NVIDIA graphics cards with Maxwell and Kepler (deprecated) GPU architecture to enable accelerated transcoding at greater scale and speed. The NVIDIA graphics cards incorporate a hardware-based video encoder called NVENC that's nearly four times faster than legacy NVIDIA CUDA encoders while consuming less power. Support for NVIDIA NVENC accelerated encoding is included in all versions of Wowza Streaming Engine for 64-bit Windows and Linux operating systems. For more information, see Server specifications for NVIDIA acceleration with Wowza Streaming Engine Transcoder.
- Wowza Streaming Engine 4.8.8.01 deprecated support for using NVIDIA Kepler GPUs, which will be unsupported in future releases.
- Older graphics drivers for your NVIDIA hardware may limit NVENC-based video encoding to approximately 30 simultaneous encoding sessions. Update your graphics driver to the latest version to avoid this limitation.
