MiniRTC's total loss is the sum of the media loss rates, not a packet-weighted
overall loss rate.
The reliable control channel's `host_info` also advertises `platform` as
`windows`, `linux`, `macos`, `ios`, or `unknown`. Desktop and iOS controllers
retain the received platform for the current session. Missing, malformed, or
unrecognized values from older or other peers map to unknown (`未知` on iOS),
without rejecting the remaining host information. Reconnecting clears the
previous peer's platform; iOS sends `ios` in its own host information.
On iOS, the received platform is also saved with each recent connection.
When preview saving is off or no preview is available, the thumbnail placeholder
shows the platform name. Existing history without platform metadata shows
`未知` until host information is received from a subsequent connection.
For black-screen diagnosis, keep Xcode's debug console open and look for
`CrossDesk` and `VideoToolbox` messages. With VideoToolbox H.264 decoding selected, look for
`VideoToolbox decoded frame` from MiniRTC and `CrossDesk delivered latest frame`
