@discordjs/voice only decrypts/forwards AUDIO (opus) — its onUdpMessage drops
every non-opus RTP packet (dist/index.mjs:2068 `!== RTP_OPUS_PAYLOAD_TYPE`, 120).
Video RTP (H264 camera + screen share, plus VP8/VP9/AV1) arrives on the same UDP
socket but was silently discarded.
New videoReceiver.ts wraps receiver.onUdpMessage (like screenShareAudio.ts):
- detects video payload types (96/98/101/102/106/116/126/127),
- decrypts them with the connection secret key/encryptionMode via the SAME
receiver.parsePacket path @discordjs/voice uses for audio (so DAVE + voice
encryption are handled identically),
- depacketizes H264 to AnnexB (single NAL, STAP-A, and FU-A fragmentation),
waiting for a keyframe (SPS/PPS/IDR) before writing,
- writes a raw .h264 elementary stream per user per burst under
<RECORDINGS_DIR>/<uid>/video-<ssrc>-<ts>.h264.
Attribution: a videoSSRC→user index is built from ssrcMap updates; a proximity
fallback mirrors screenShareAudio's inferScreenShareOwner. Bot's own video is
skipped.
Unit tests: tests/videoReceiver.test.ts (AnnexB start code, keyframe gating,
FU-A reassembly, orphan-fragment tolerance) — 5/5 green.
Phase A only (capture raw h264). Phase B (ffmpeg decode+mux to MP4/WebM +
persist) and Phase C (frontend playback) are follow-ups.
