Producer is an abstract class to extract frames from a source (image directory, video file, webcam stream, etc.). It has the basic and common functions (e.g. getFrame, release & isOpened).
|
explicit |
Constructor of Producer.
repeatWhenFinished | bool indicating whether the producer must be restarted after it finishes. |
|
virtual |
Destructor of Producer. It is virtual so that any children class can implement its own destructor.
|
protected |
Protected function which checks that the frames keeps their integry (some OpenCV versions might return corrupted frames within a video or webcam with a size different to the standard resolution). If the frame is corrupted, it is set to an empty cv::Mat.
frame | cv::Mat with the frame matrix to be checked and modified. |
|
protected |
It performs flipping and rotation over the desired cv::Mat.
cvMat | cv::Mat with the frame matrix to be flipped and/or rotated. |
|
pure 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.
capProperty | int indicating the property to be modified. |
Implemented in op::VideoCaptureReader, op::ImageDirectoryReader, op::WebcamReader, op::VideoReader, and op::IpCameraReader.
|
pure virtual |
Implemented in op::VideoCaptureReader, and op::ImageDirectoryReader.
cv::Mat op::Producer::getFrame | ( | ) |
Main function of Producer, it retrieves and returns a new frame from the frames producer.
|
pure 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.).
Implemented in op::VideoCaptureReader, op::WebcamReader, op::ImageDirectoryReader, op::VideoReader, and op::IpCameraReader.
|
protectedpure virtual |
Function to be defined by its children class. It retrieves and returns a new frame from the frames producer.
Implemented in op::VideoCaptureReader.
|
inline |
This function returns the type of producer (video, webcam, ...).
|
protected |
Protected function which checks that the frame producer has ended. If so, if resets or releases the producer according to mRepeatWhenFinished.
|
pure virtual |
This function returns whether the Producer instance is still opened and able to retrieve more frames.
Implemented in op::VideoCaptureReader, and op::ImageDirectoryReader.
|
protected |
Protected function which forces the producer to get frames at the rate of get(CV_CAP_PROP_FPS).
|
pure virtual |
This function releases and closes the Producer. After it is called, no more frames can be retrieved from Producer::getFrame.
Implemented in op::VideoCaptureReader, and op::ImageDirectoryReader.
|
pure 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.
capProperty | int indicating the property to be modified. |
value | double indicating the new value to be assigned. |
Implemented in op::VideoCaptureReader, op::ImageDirectoryReader, op::WebcamReader, op::VideoReader, and op::IpCameraReader.
|
pure virtual |
Implemented in op::VideoCaptureReader, and op::ImageDirectoryReader.
void op::Producer::setProducerFpsMode | ( | const ProducerFpsMode | fpsMode | ) |
This function sets whether the producer must keep the original fps frame rate or extract the frames as quick as possible.
fpsMode | ProducerFpsMode parameter specifying the new value. |
