Description

The Camera Seek sample demonstrates how to replay a video and use the 'seek to timestamp/event' feature to seek to any point in the video.

Running the sample

The Camera Seek sample, sample_camera_seek, accepts the following parameters:

./sample_camera_seek --video=[path/to/video]

where:

--video=[path/to/video]
    Path to the video file.
    Default value: path/to/data/samples/sfm/triangulation/video_0.h264

The sample works with the following keyboard inputs:

T  : changes the seek mode to timestamp.
F  : changes the seek mode to frame event.
Left Arrow  : steps backward (10 for frames, 1000000 for timestamp).
Right Arrow  : steps forward (10 for frames, 1000000 for timestamp).
Space : pauses the video.

Seeking is available in both normal and paused states.

Examples

./sample_camera_seek --video=/path/to/file.h264
