| Name | Description |
|---|---|
| stat::buffer.max | a number of buffered frames |
| stat::elapsed | waiting for the next frame interval in msec |
| stat::buffer.min | a minumal buffer size |
| stat::buffer.current | a number of currently buffered frame |
| stat::buffer.overflow | a number of buffer overflows |
| stat::sync.take_frames | a time to get frames from streams in msec |
| stat::put_frame.bg | a time to put a background frame in msec |
| stat::sync.put_frames | a time to put all the frames in sync mode |
| stat::mix_audio | a time to mix audio from streams |
| stat::sync.mix_frames | ------------------------------------------ |
| stat::sync.mix_cycle | ------------------------------------------ |
| stat::mix_output | a time to mix all the frames together in msec |
| stat::fps_mix | frame rate of the mixing operation |
| stat::plugins.perf | performance of all the plugins that are added to the object (how long does it take to process a frame with all the plugins) |
| stat::plugins.count | a number of plugins added to the object |
| stat::reset_counter | how many times was the statistics reset |
| stat::live | indicates whether a source is from a live feed (e.g. a camera) |
| stat::breaks | a number of breaks - frames with "Break" flag, when a frame is expected but is not received from a source |
| stat::dups | a number of duplicated frames |
| stat::pauses | a number of frames processed while a source is paused |
| stat::skipped | a number of skipped frames |
| stat::added | a number of added frames to keep the overall frame rate stable |
| stat::tc_breaks | a number of timecode issues (when the current frame contains a timecode that is different from the previous more than for 1 frame, e.g. "01:23:45:12" and "01:23:45:15"). Grows fast for fast playback |
| stat::audio_breaks | a number of frames with silence at the end (without audio) |
| stat::time_breaks | a number of issues when an end time of the previous frame doesn't match a start time of the current frame |
| stat::time_over_200 | a number of frames which processing takes more than 2 frame durations |
| stat::time_over_166 | a number of frames which processing takes between 1.66 and 2 times more than the frame duration |
| stat::time_over_133 | a number of frames which processing takes between 1.33 and 1.66 times more than the frame duration |
| stat::time_less_50 | a number of frames which processing takes less than 0.5 frame duration |
| stat::video | a video format width(raw_bytes)xheight(colorspace)@frame_rate (aspect_ratio) |
| stat::audio | an audio format channels,sample_rate,bits |
| stat::video_frames | a number of processed video frames |
| stat::video_time | a total duration of the processed video in seconds |
| stat::audio_samples | a total number or processed audio samples |
| stat::audio_time | a total duration of the processed audio in seconds |
| stat::av_sync | a difference between audio and video times in msec |
| stat::vt_sync | a difference between a video time and an internal system clock in msec |
| stat::vh_sync | a difference between a video time and a hardware timer of a source device (works for Blackmagic devices only) |
| stat::stat_perf | a time interval to grab the statistics in msec |
| stat::rate_correct | -------------------------------------- |
| stat::rate_wait | -------------------------------------- |
| stat::rate_control | -------------------------------------- |
| stat::out_time | average timing to output frames (average, max, and min times to send a frame to an output) |
| stat::fps_desired | desired frame rate |
| stat::fps_avg | average frame rate |
| stat::jitter | a jitter interval for frames processing |
| stat::max_time | a maximal time to process a frame |
| stat::min_time | a minimal time to process a frame |
