# Run the rust-sdks local_video subscriber against the local dev SFU and surface
|
|
# FlexFEC stats. The subscriber logs "Video FEC ..." lines as repair packets arrive
|
|
# and recovery payload is accepted.
|
|
#
|
|
# Usage:
|
|
# scripts/flexfec/run-subscriber.sh [extra subscriber args...]
|
|
#
|
|
# Env overrides:
|
|
# RUST_SDKS_DIR path to the rust-sdks5 checkout (default: ../rust-sdks5)
|
|
# LIVEKIT_URL default ws://127.0.0.1:7880
|
|
# LIVEKIT_API_KEY / LIVEKIT_API_SECRET default devkey / secret
|
|
# ROOM room name (default flexfec-test)
|
|
# SUB_IDENTITY participant identity (default flexfec-sub)
|
|
# RUST_LOG log filter (default info)
|
|
# LOG_DIR where to write logs (default scripts/flexfec/logs)
|
|
# FEC_ONLY if set to 1, only print FEC + frame-latency lines to the console
|
|
#
|
|
# Frame latency: when the publisher runs with --attach-timestamp/--attach-frame-id, the
|
|
# subscriber emits "Subscriber frame latency: ..." lines (capture->receive->decode). The
|
|
# receive_to_decode value is the jitter-buffer wait, which is where FEC-ON and RTX-only
|
|
# diverge; capture_to_decode is the end-to-end glass-to-decode latency.
