Glad is a multi-language code generator that produces loaders for Khronos graphics APIs (OpenGL, Vulkan, EGL, GLX, WGL). It parses official XML specification registries and generates C/C++ and Rust source files that load all required function pointers at runtime, supporting multiple contexts (MX), header-only builds, debug callbacks, on-demand loading, and alias resolution. The architecture is modular: a Python CLI dispatches to language-specific generators via a plugin system, using Jinja2 templates for output. It includes CMake integration, extensive compile/run tests, and examples for GLFW, SDL2/3, Vulkan, and embedded contexts. The codebase demonstrates strong engineering practices—clean separation of parsing, generation, and template rendering, with reusable patterns for configuration, plugin discovery, and XML processing.
Yasea is an Android live-streaming library and demo application that captures camera video and microphone audio, applies real-time GPU image filters, hardware-encodes to H.264/AAC via MediaCodec, muxes into FLV, and publishes over RTMP to servers such as SRS. The main entry point is SrsPublisher, which orchestrates SrsCameraView (an OpenGL ES preview surface), SrsEncoder (MediaCodec lifecycle and format negotiation), SrsFlvMuxer (FLV-over-RTMP publishing), and SrsMp4Muxer (simultaneous MP4 recording). The demo app (MainActivity) provides a working UI for URL entry, publish/pause, camera switching, recording, and filter selection. Architecturally, the repo is a Gradle project with two modules: a reusable Android library (library/) and a demo app (app/). The library is a monolith that bundles large vendored third-party codebases as source: Google's libyuv (native YUV/RGB conversion and scaling), mp4parser (ISO BMFF/MP4 parsing and authoring), simple-rtmp (RTMP client protocol), and MagicCamera (40+ GPU image filters with GLSL shaders). The repo's own code is the net.ossrs.yasea package, which integrates these pieces: camera frames flow through the GLSurfaceView filter chain as RGBA, are converted to I420/NV12 by the libenc JNI bridge (libenc.cc wrapping libyuv), encoded by MediaCodec, and muxed to FLV/MP4. Audio is captured via AudioRecord and encoded to AAC. Despite a recent commit, the codebase is frozen in the 2017-2020 Android era: compileSdk/targetSdk 26, Android support library 26.1.0, the deprecated Camera API, Gradle 6.5 with AGP 4.1.1, and a mips ABI that modern NDKs no longer support. The native build is commented out in library/build.gradle, and 285 open issues remain. Technical drift is high. This is purely an application/library repo - no data pipelines, notebooks, or research components.
