StreamLift

Real-time super-resolution for interactively streamed media.

Overview

StreamLift is a collection of AI-optimized algorithms to achieve one or more domain-dependent goals:

• Reduce encoder (H.264/265) latency or improve throughput at the server
• e.g. maximize simultaneous streams per streaming node
• Reduce decoder latency at the client
• e.g. enable high-refresh rates, resolution or both
• Maximize streaming efficiency:
• preserve static elements like UI/text/crosshair
• improve streaming quality at low bandwidth

Architecture


The SDK does not include video encoding and decoding capabilities; instead, it relies on the host application to interface with appropriate encoding (NvEnc) and decoding (any comaptible decoding) libraries.

Requirements

• Server API:
• OS: Windows or Linux 64bit
• GPU: Nvidia Turing+ GPU
• Optional: NvEnc (H.264/265) capable GPU
• Arch: x86_64 or Aarch64
• API: CUDA 12.1+
• Client D3D11 API:
• OS: Windows 64bit
• GPU: Any D3D11 Capable GPU
• Optional: Video decode (H.264/265) capability
• Arch: x86_64
• API: DirectX11 (SM 5.0+)
• Client CUDA API:
• OS/Arch: Windows or Linux 64bit
• GPU: Nvidia Turing+ GPU
• Optional: NvDec (H.264/265) capable GPU
• Arch: x86_64 or Aarch64
• API: CUDA 12.1+

Getting Started

The host application must have a server and client component. The server component is based on CUDA. The client component may choose between CUDA or D3D11 APIs.

• Server (CUDA only):
• Include: streamlift_server.h"
• Link:
• Windows: streamlift_server.lib
• Linux/Debian: libstreamlift_server.so
• Client (CUDA):
• Include: streamlift_client_cuda.h
• Link:
• Windows: streamlift_client_cuda.lib
• Linux/Debian: libstreamlift_client_cuda.so
• Client (D3D11):
• Include: streamlift_client_d3d11.h
• Link:
• Windows-only: streamlift_client_d3d11.lib

Basic Usage

#include "streamlift_*.h"

Streamlift_*_Init(...)

for(;;)
Streamlift_*_ProcessFrame(...)

Streamlift_*_DeInit(...)
