Spangle Media Server (WIP)

THIS PROJECT IS WORKING IN PROGRESS

Current status: RTMP (classic + enhanced) ingest of H.264/H.265/AV1 + AAC works end-to-end into HLS — MPEG-2 TS or CMAF/fMP4 segments, optionally LL-HLS (partial segments + blocking playlist reload) — served over HTTP by Spangle.MediaServer with per-stream routing (/hls/{stream}/playlist.m3u8).

See docs/ARCHITECTURE.md for the data flow, the data formats at each boundary, and where state lives.

Quick try:

$ dotnet run --project src/Spangle.MediaServer
$ ffmpeg -re -f lavfi -i testsrc=size=640x360:rate=30 -f lavfi -i sine=frequency=440 \
    -c:v libx264 -g 60 -pix_fmt yuv420p -c:a aac -f flv rtmp://localhost:1935/live/test
# then open http://localhost:8080/ (test player) or http://localhost:8080/hls/playlist.m3u8

Planning Goal

Media Streaming

Advanced Features (I don't know if I'm going to do it)

• DRM
• Transcoder integration (Hardware, x26X)

Others

• Target mainly UGC content
• Almost pure C#
