SRS (Simple Realtime Server) is a high-performance, multi-protocol media streaming server primarily written in C++ with a newer Go-based proxy component (SRSX). It ingests, processes, and delivers live audio/video streams via RTMP, WebRTC (WHIP/WHEP), HLS, HTTP-FLV, SRT, and GB28181. The core C++ engine uses a coroutine model built on state-threads, implements stream forwarding, transcoding via FFmpeg, and provides a full HTTP API for management. The Go proxy component (cmd/proxy, internal/) adds load balancing, Redis integration, and protocol proxying for RTMP/HTTP/WebRTC, designed to scale origin/edge deployments. The repository also includes extensive research code, blackbox integration tests, and vendored third-party libraries (FFmpeg 4, OpenSSL 1.1, gperftools, SRT, libsrtp) that have been customized with a '-fit' suffix. This hybrid architecture is actively developed with multiple CI workflows and a large test suite, though some vendored dependencies are older and may require security updates.
This repository is a desktop application for extracting subtitles from video files using OCR and subtitle detection. It integrates PaddleOCR inference models for text recognition, uses a separate binary tool (VideoSubFinder) for detecting subtitle regions, and employs the Sushi library for subtitle synchronization. The application is written in Python with a PyQt-based GUI (gui.py) and provides a modular backend with separate modules for OCR, subtitle detection, concurrent task management, and hardware acceleration. The project includes pre-compiled binaries for Windows, Linux, and macOS, as well as CI/CD workflows for building Windows executables. While the overall architecture is functional and suitable for its purpose, the code's internal quality and reusability cannot be fully assessed without inspecting source contents. The repository is actively maintained and has a large user base, but it is primarily a monolithic application rather than a reusable library.
