Capture Replay

PCAP capture file replay. Functions are not thread safe, and should only be called from the main thread.

int cepton_sdk_capture_replay_is_open(void)

Returns whether capture replay is open.

CeptonSensorErrorCode cepton_sdk_capture_replay_open(const char *const path)

Opens capture replay.

Must be called before any other replay functions listed below.

Parameters

• path: Path to PCAP capture file.

CeptonSensorErrorCode cepton_sdk_capture_replay_close(void)

Closes capture replay.

const char *cepton_sdk_capture_replay_get_filename(void)

Returns capture replay file name.

int64_t cepton_sdk_capture_replay_get_start_time(void)

Returns capture start Unix timestamp [microseconds].

float cepton_sdk_capture_replay_get_position(void)

Returns capture file position [seconds].

float cepton_sdk_capture_replay_get_length(void)

Returns capture file length [seconds].

int cepton_sdk_capture_replay_is_end(void)

Returns whether at end of capture file.

This is only relevant when using resume_blocking methods.

CeptonSensorErrorCode cepton_sdk_capture_replay_seek(float position)

Seek to capture file position [seconds].

Parameters

• position: Seek position in range [0.0, capture length).

CeptonSensorErrorCode cepton_sdk_capture_replay_set_enable_loop(int enable_loop)

Sets capture replay looping.

If enabled, replay will automatically rewind at end.

int cepton_sdk_capture_replay_get_enable_loop(void)

Returns whether capture replay looping is enabled.

CeptonSensorErrorCode cepton_sdk_capture_replay_set_speed(float speed)

Sets speed multiplier for asynchronous replay.

float cepton_sdk_capture_replay_get_speed(void)

Returns capture replay speed.

CeptonSensorErrorCode cepton_sdk_capture_replay_resume_blocking_once(void)

Replay next packet in current thread without sleeping.

Pauses replay thread if running.

CeptonSensorErrorCode cepton_sdk_capture_replay_resume_blocking(float duration)

Replay multiple packets synchronously.

No sleep between packets. Pauses replay thread if running.

Parameters

• duration: Duration to replay. Must be non-negative.

int cepton_sdk_capture_replay_is_running(void)

Returns true if replay thread is running.

CeptonSensorErrorCode cepton_sdk_capture_replay_resume(void)

Resumes asynchronous replay thread.

Packets are replayed in realtime. Replay thread sleeps in between packets.

CeptonSensorErrorCode cepton_sdk_capture_replay_pause(void)

Pauses asynchronous replay thread.
