Cat-catch is a browser-based media utility designed to detect, capture, and manage web-based video and audio resources. It functions as a comprehensive sniffing and download management system, enabling users to identify hidden or protected media assets directly from active web pages. The tool specializes in reconstructing fragmented streaming protocols, such as DASH and M3U8, into complete files while providing options for real-time stream recording and playback control.
The project distinguishes itself through its deep integration with local system environments and external automation tools. It acts as a bridge between the browser and local command-line applications, utilizing custom protocol handlers to offload complex downloading and transcoding tasks. Beyond individual capture, the tool includes peer-to-peer networking capabilities, allowing users to share files and communicate directly between devices on a local network without relying on external servers.
The system provides extensive control over the capture process, including regex-driven filtering, domain-level blocking, and dynamic metadata injection for standardized file organization. Users can manipulate media playback speeds, simulate mobile environments to trigger specific resource delivery, and configure custom headers to bypass access restrictions. The tool also supports advanced workflows by allowing the transmission of decryption keys and resource data to external scripts for specialized media processing.
