Member Function Documentation

static const char* opentl::output::VideoWriter::codecFileExtension ( int  codecID  )  [inline, static]

static const char* opentl::output::VideoWriter::codecName ( int  codecID  )  [inline, static]

bool opentl::output::VideoWriter::init ( const std::string &  filename,
int  width,
int  height,
double  fps,
Codec  codec,
ColorMode  colorMode = VideoWriter::COLOR 
)

Initializes the video writer. Calling second time closes the existing video file and starts writing to another file

Parameters:
filename Name of the file in which to write video
width Width in pixels of the output video
height Height in pixels of the output video
fps Framerate (frames per second) in the output video
codec Which codec to use. See opentl::output::Videowriter::Codec for supported codecs
colorMode Which color mode to use. See opentl::output::VideoWriter::ColorMode for available color modes
Returns:
If video writer has been successfully initialized

void opentl::output::VideoWriter::release (  ) 

Finishes writing to video file and cleans up. This method is called when a VideoWriter object is deleted.

void opentl::output::VideoWriter::writeFrame ( const opentl::core::cvdata::Image img  ) 

Writes an image as the next frame into the video file. init method must be called before starting writing frames. Image is automatically rescaled and converted to needed pixel format

Parameters:
img Image to write as frame
