jack_unique_t _jack_position::unique_1

unique ID

Definition at line 703 of file types.h.

jack_time_t _jack_position::usecs

monotonic, free-rolling

Definition at line 704 of file types.h.

jack_nframes_t _jack_position::frame_rate

current frame rate (per second)

Definition at line 705 of file types.h.

jack_nframes_t _jack_position::frame

frame number, always present

Definition at line 706 of file types.h.

jack_position_bits_t _jack_position::valid

which other fields are valid

Definition at line 708 of file types.h.

int32_t _jack_position::bar

current bar

Definition at line 711 of file types.h.

int32_t _jack_position::beat

current beat-within-bar

Definition at line 712 of file types.h.

int32_t _jack_position::tick

current tick-within-beat

Definition at line 713 of file types.h.

float _jack_position::beats_per_bar

time signature "numerator"

Definition at line 716 of file types.h.

float _jack_position::beat_type

time signature "denominator"

Definition at line 717 of file types.h.

double _jack_position::frame_time

current time in seconds

Definition at line 722 of file types.h.

double _jack_position::next_time

next sequential frame_time (unless repositioned)

Definition at line 723 of file types.h.

jack_nframes_t _jack_position::bbt_offset

frame offset for the BBT fields (the given bar, beat, and tick values actually refer to a time frame_offset frames before the start of the cycle), should be assumed to be 0 if JackBBTFrameOffset is not set. If JackBBTFrameOffset is set and this value is zero, the BBT time refers to the first frame of this cycle. If the value is positive, the BBT time refers to a frame that many frames before the start of the cycle.

Definition at line 727 of file types.h.

float _jack_position::audio_frames_per_video_frame

number of audio frames per video frame. Should be assumed zero if JackAudioVideoRatio is not set. If JackAudioVideoRatio is set and the value is zero, no video data exists within the JACK graph

Definition at line 744 of file types.h.

jack_nframes_t _jack_position::video_offset

audio frame at which the first video frame in this cycle occurs. Should be assumed to be 0 if JackVideoFrameOffset is not set. If JackVideoFrameOffset is set, but the value is zero, there is no video frame within this cycle.

Definition at line 751 of file types.h.

jack_unique_t _jack_position::unique_2

unique ID

Definition at line 764 of file types.h.
