ChadServr - Video Chunk Processing Server

A robust, high-performance video chunk processing server written in C++. ChadServr provides a flexible API for uploading, processing, and managing video chunks, making it ideal for video streaming applications, transcoding services, and media processing pipelines.

Features

• HTTP API for video chunk upload and management
• Parallel processing using a configurable thread pool
• FFmpeg integration for video transcoding and manipulation
• Stateful chunk tracking with detailed metadata
• Configuration management via JSON files
• Comprehensive logging system
• Storage management with automatic cleanup

Requirements

• C++17 compatible compiler
• CMake 3.10+
• Boost libraries (system, thread)
• FFmpeg command-line tools
• nlohmann/json library (automatically downloaded by CMake)

Building

mkdir build && cd build
cmake ..
make

Running

# From the build directory
./bin/chadservr

The server will start on port 8080 by default, as specified in the configuration file.

Configuration

Edit config/server_config.json to configure the server:

{
  "server": {
    "port": 8080,
    "worker_threads": 4
  },
  "video_processing": {
    "thread_pool_size": 2,
    "storage_path": "storage/processed",
    "temp_path": "storage/temp",
    "max_chunks": 100
  }
}
