Detailed Description

MntPPMWriter is a component that takes in a MntYUVFrame object and writes the object to disk as PPM image file.

The filename of the image file is prefixed by a string specified by user, and is suffixed by the frame number and frame type.

Member Function Documentation

void MntPPMWriter::recv (  MntData *  data  )  [virtual]

This method takes a uncompressed YUV frame (an MntYUVFrame object) as input, transform the frame into RGB color space, and output it to disk as the ppm file with name <prefix><counter><type>.ppm, where prefix is specified by users through the constructor, counter is the frame number in display order, and type is a character of either i, p or b to indicate the frame type of this frame in the compressed MPEG stream. The input YUV is assumed to be of 4:2:0 color subsampling. Reimplemented from MntComponent.
