Implementation Plan

Implemented

• Repo-local persistence machinery.
• First architecture map.
• Example config for one video source plus two audio sources.
• Sender device discovery script.
• Sender launch script with dry-run mode and per-source FFmpeg commands.
• OBS receiver setup notes.

Temporary

• Audio and video are separate SRT endpoints. This preserves OBS mixing authority but may need latency tuning.
• Audio defaults to AAC inside MPEG-TS for compatibility; test Opus later only if there is a concrete reason.
• Desktop capture uses gdigrab first because it is broadly available. ddagrab is a candidate once the installed FFmpeg build is confirmed.
• The scripts assume Windows sender and OBS receiver on the same LAN.

Next

1. Run scripts/sender-discover.ps1 on the sender and record the actual device names.
2. Smoke-test one video stream into OBS.
3. Smoke-test each audio source independently.
4. Tune SRT latency and FFmpeg buffering for the local network.
5. Decide whether a small OBS scene/source generator is worth adding.
6. Reconsider plugin/fork only if standard OBS Media Source cannot preserve the required behavior.
