mpegts (moved to earlier for OBS B-frame stability) only supports H264.
Browser (WHIP) publishing sends VP8 or VP9 depending on the machine's
available encoders, which mpegts can't mux at all — confirmed live,
'the MPEG-TS variant of HLS supports H264 video only' crash loop.
lowLatency supports the broader codec set browser publishing actually
needs.
Real risk, not resolved by this alone: lowLatency is what caused the
original OBS B-frame muxer crashes this session already fixed once by
moving to mpegts. If that recurs, the correct fix is two MediaMTX
instances (one per hlsVariant) since it's a global, not per-path,
setting — not flip-flopping between the two.
