JOY4 is a Go audio/video library and streaming server providing well-designed interfaces for reading, writing, and transcoding media formats like MP4, FLV, and MPEG-TS, plus RTMP/HTTP-FLV live streaming servers. It includes RTSP/RTMP clients, packet filters, pubsub queues, and optional FFmpeg cgo bindings. The README now directs users to its successor, joy5.

Use cases

• build an RTMP or HTTP-FLV live streaming server in Go
• transcode audio and video between media formats
• read and probe MP4, FLV, or MPEG-TS files
• pull streams from RTSP cameras with bug tolerance
• publish or play RTMP streams with OBS or ffmpeg
• parse H264 SPS/PPS and AAC headers in Go
• build multi-channel live streaming with pubsub buffers

When to choose

• you need a pure-Go media muxing/demuxing and streaming toolkit
• you want a lightweight RTMP/HTTP-FLV server embedded in a Go application
• you need RTSP camera ingestion with high-level error tolerance

When to avoid

• you are starting a new project - the author recommends joy5 instead
• you need HLS or MPEG-DASH serving, which is unimplemented
• you need actively maintained code with recent releases
