GPU-Accelerated Video Encoding - Nvidia

Multi-GPU encoding
• N GOPs for N GPUs
– Coarse-grain parallelism
– Better for offline compression
– Higher utilization of GPU resources
– Requires N times more memory on CPU to handle processing
I P B B I P B B
– Drawbacks: must be careful when concatenating GOP structures, CPU
multiplexing may become a bottleneck,
– Requires N times more memory on the host to process video
