AtomicAkarin.Mooncake

libav/libswscale-based RTSP client for .NET Core

This project is still under development, you may check out other branches for latest progress.

Modules

• Lotus(Core/Shim): Handles libav/libswscale invocations and manages related structures
• Mooncake: Initializes FFmpegShim and/or hosts frame handler plugins
• Bakery: WebM chunks in-memory (planned) server

Goals and Roadmap

• FrameReader: Open supported media files or urls (e.g rtsp://) via avformat

• FrameReader: Receive and decode frames via avcodec

---

• FrameScaler: Convert frames into different pixel formats (e.g YUV420P to RGB24) via swscale

---

• Dump AVFrame into SixLabors.ImageSharp.Image (feature not longer required)

• AVPacketStream: Encapulse AVPacket as System.IO.Stream (read-only)

Individual packets can be dumped out (e.g re-encode frames as JPEG and dump into .NET) as simple as Stream.CopyTo().

• StreamIOContext: Encapsule System.IO.Stream (read-only) as AVIOContext
• StreamIOContext: Write support

FileStream and MemoryStream can be provided to AVFormat as input source or output destination, which enables in-memory re-muxing.

---

• Re-encode and mux into VP9 WebM

• Serve output WebM (cached in in-memory) chunks over HTTP
