enum OMX_AUDIO_MIDIPLAYBACKSTATETYPE

MIDI Playback States

Enumerator:

OMX_AUDIO_MIDIPlayBackStateUnknown	Unknown state or state does not map to other defined states
OMX_AUDIO_MIDIPlayBackStateClosedEngaged	No MIDI resource is currently open. The MIDI engine is currently processing MIDI events.
OMX_AUDIO_MIDIPlayBackStateParsing	A MIDI resource is open and is being primed. The MIDI engine is currently processing MIDI events.
OMX_AUDIO_MIDIPlayBackStateOpenEngaged	A MIDI resource is open and primed but not playing. The MIDI engine is currently processing MIDI events. The transition to this state is only possible from the OMX_AUDIO_MIDIPlayBackStatePlaying state, when the 'playback head' reaches the end of media data or the playback stops due to stop time set.
OMX_AUDIO_MIDIPlayBackStatePlaying	A MIDI resource is open and currently playing. The MIDI engine is currently processing MIDI events.
OMX_AUDIO_MIDIPlayBackStatePlayingPartially	Best-effort playback due to SP-MIDI/DLS resource constraints
OMX_AUDIO_MIDIPlayBackStatePlayingSilently	Due to system resource constraints and SP-MIDI content constraints, there is no audible MIDI content during playback currently. The situation may change if resources are freed later.
