SDP offer advertises profile-level-id=42e01f (constrained baseline) but
x264 encoded the default High profile — Discord's receiver configures its
decoder from the negotiated profile, so the High-profile bitstream failed
to decode → black GoLive tile despite valid access units + correct RTP
timestamps (fixed in 42a503c).
- Add -profile:v baseline to H264 encoder options (matches @dank074's
proven config; SPS now 6742c01e → profile_idc=66 baseline, aligns with
the 42e01f fmtp).
- Default x264 tune film → zerolatency (no lookahead — correct for live
GoLive; @dank074 uses it).
- Update goLive-port test to assert baseline + zerolatency.
