Smpte2110OutputAudio

A reference to one of the input's named audios, bundled into an audio essence — may itself be a stereo pair or multi-channel group, not necessarily a single raw channel.

inputName names the input the audio comes from, and audioInputName normally references that input's own payload.audios[].name; see CPSmpte2110Output in cp.py for how the pair resolves to a real decode stream. The two together mirror SdiOutputAudioConfig — inputName was missing here originally, which left the reference implicit and resolved against every input at once.

For an input using audioAutoSelect (where audios aren't individually named by the user), audioInputName instead holds one of the reserved Audio_1..Audio_8 identifiers — CP's own decode-stream identifiers for that input's auto-selected decode streams, used directly with no translation at the cp.py boundary (see _build_smpte2110_named_audio_streams / _smpte2110_audio_essence_from_stream in cp.py).

lipSyncOffset is deliberately not exposed here — channels-api doesn't let a user set it; it's only adjustable from the CP Advanced UI.
