  1. Volar Video a video encoding project

  2. Our Customer • Volar Video in downtown lex • Specialize in live event streaming • Architect the software to make that happen

  3. Team Members • Implement h.264 encoder for Nvidia CUDA and Nvidia NVENC • Sam Morris: CUDA • Derek Buchanan: NVENC • SDKs for the Volar client API • Steven Hornung • Anthony Saunders

  4. Project Overview • Problem: • Current video encoding is performed through software and executed solely on the CPU. Doing so causes CPU to idle at 60% while encoding 720p video on a modern i7 processor. • Solution: • Implement an h.264 video encoder • Two proposed encoding methods: • Nvidia NVCUVID(general GPU computing) • Nvidia NVENC(dedicated VE hardware) • Create a command line interface • Gather performance metrics for analysis and comparison between the two

  5. Production Truck

  6. Hardware Requirements • Kepler-based GPU, GTX 760+ (NVENC) • G8x or higher GPU(NVCUVID) • Lots of RAM • Windows, Linux(optional) • Libraries (ffmpeg...)

  7. Video Encoding • Video encoding is... • analog to digital signal processing • compression • performed by a 'codec' • very processor intensive • h.264(MPEG-4) advanced video coding • Most common video compression formats • ~2:1 compression ratio • Blu-ray, vimeo,youtube,itunesstore

  8. Nvidia NVCUVID • a video codec sdk • Allows programmer to parallelize video encoding across PEs on GPU

  9. NvidiaNVENC • NVENC enables software developers to access the high-performance H.264 hardware video encoder introduced in Kepler-class NVIDIA GPUs • By dedicating hardware to the encoding task, it also frees up CUDA cores and/or the CPU to be used for other compute-intensive tasks. • This hardware encoder is designed to encode 1080p video at 240 fps
