#include <videoReader.hpp>
Inherits op::VideoCaptureReader.
VideoReader is a wrapper of the cv::VideoCapture class for video. It allows controlling a video (e.g. extracting frames, setting resolution & fps, etc).

Constructor of VideoReader. It opens the video as a wrapper of cv::VideoCapture. It includes a flag to indicate whether the video should be repeated once it is completely read.
- Parameters
-
videoPath | const std::string parameter with the full video path location. |
imageDirectoryStereo | const int parameter with the number of images per iteration (>1 would represent stereo processing). |
cameraParameterPath | const std::string parameter with the folder path containing the camera parameters (only required if imageDirectorystereo > 1). |

const int |
capProperty | ) |
|
|
virtual |
This function is a wrapper of cv::VideoCapture::get. It allows getting different properties of the Producer (fps, width, height, etc.). See the OpenCV documentation for all the available properties.
- Parameters
-
capProperty | int indicating the property to be modified. |
- Returns
- double returning the property value.
Implements op::VideoCaptureReader.
std::vector<cv::Mat> op::VideoReader::getCameraExtrinsics |
( |
| ) |
|
|
virtual |
It retrieves and returns the camera extrinsic parameters from the frames producer.
- Returns
- std::vector<cv::Mat> with the camera extrinsic parameters.
Implements op::Producer.
std::vector<cv::Mat> op::VideoReader::getCameraIntrinsics |
( |
| ) |
|
|
virtual |
It retrieves and returns the camera intrinsic parameters from the frames producer.
- Returns
- std::vector<cv::Mat> with the camera intrinsic parameters.
Implements op::Producer.
std::vector<cv::Mat> op::VideoReader::getCameraMatrices |
( |
| ) |
|
|
virtual |
It retrieves and returns the camera matrixes from the frames producer.
- Returns
- std::vector<cv::Mat> with the camera matrices.
Implements op::Producer.
std::string op::VideoReader::getNextFrameName |
( |
| ) |
|
|
virtual |
This function returns a unique frame name (e.g. the frame number for video, the frame counter for webcam, the image name for image directory reader, etc.).
- Returns
- std::string with an unique frame name.
Implements op::VideoCaptureReader.
bool op::VideoReader::isOpened |
( |
| ) |
const |
|
inlinevirtual |
This function returns whether the Producer instance is still opened and able to retrieve more frames.
- Returns
- bool indicating whether the Producer is opened.
Reimplemented from op::VideoCaptureReader.
void op::VideoReader::set |
( |
const int |
capProperty, |
|

) |
| |
|
virtual |
This function is a wrapper of cv::VideoCapture::set. It allows setting different properties of the Producer (fps, width, height, etc.). See the OpenCV documentation for all the available properties.
- Parameters
-
capProperty | int indicating the property to be modified. |
value | double indicating the new value to be assigned. |
