Enumeration Type Documentation

Different Control types.

Enumerator
SPA_CONTROL_Invalid
SPA_CONTROL_Properties	SPA_TYPE_OBJECT_Props.
SPA_CONTROL_Midi	spa_pod_bytes with raw midi data (deprecated, use SPA_CONTROL_UMP)
SPA_CONTROL_OSC	spa_pod_bytes with an OSC packet
SPA_CONTROL_UMP	spa_pod_bytes with raw UMP (universal MIDI packet) data. The UMP 32 bit words are stored in native endian format.
_SPA_CONTROL_LAST	not part of ABI
