Public Member Functions | |
CVideoFileWriter () | |
Default constructor, which does not open any file. | |
virtual | ~CVideoFileWriter () |
Destructor. | |
bool | open (const std::string &out_file, double fps, const mrpt::vision::TImageSize &frameSize, const std::string &fourcc=std::string(""), bool isColor=true) |
Open a file for writing the video. | |
void | close () |
Finish the file writing and close the file output. | |
const CVideoFileWriter & | operator<< (const mrpt::utils::CImage &img) const |
Write image to the video file. | |
bool | writeImage (const mrpt::utils::CImage &img) const |
Write image to the video file (method function, alternative to the operator <<). | |
Private Attributes | |
mrpt::utils::void_ptr_noncopy | m_video |
A pointer to CvVideoWriter. | |
mrpt::vision::TImageSize | m_img_size |
A copy of the video size. |
The output file is open when calling "open", and it's closed at destructor or after calling "close".
Example of usage:
CVideoFileWriter vid; vid.open("test.avi","MJPG",15,TPixelCoord(320,200)); CImage img(320,200); vid << img; vid.close;
There are two methods for adding frames to the video:

mrpt::vision::CVideoFileWriter::CVideoFileWriter | ( | ) |
Default constructor, which does not open any file.
virtual mrpt::vision::CVideoFileWriter::~CVideoFileWriter | ( | ) | [virtual] |
Destructor.
void mrpt::vision::CVideoFileWriter::close | ( | ) |
Finish the file writing and close the file output.
bool mrpt::vision::CVideoFileWriter::open | ( | const std::string & | out_file, | |
double | fps, | |||
const mrpt::vision::TImageSize & | frameSize, | |||
const std::string & | fourcc = std::string("") , |
|||
bool | isColor = true | |||
) |
Open a file for writing the video.
out_file | The video file to create for output. | |
fourcc | The video codec, as a string. See notes below. fps The video FPS (frames per seconds). | |
frameSize | The size of the video frames. All subsequent images must be of this size. | |
isColor | Set to false to create a grayscale video. |
Other valid values for "fourcc" are: "PIM1" -> MPEG1, "MJPG" -> Motion JPEG, "XVID", etc...
const CVideoFileWriter& mrpt::vision::CVideoFileWriter::operator<< | ( | const mrpt::utils::CImage & | img | ) | const |
Write image to the video file.
std::exception | On any error |
bool mrpt::vision::CVideoFileWriter::writeImage | ( | const mrpt::utils::CImage & | img | ) | const |
Write image to the video file (method function, alternative to the operator <<).
