Member Function Documentation

virtual void VideoReader::read

(

void

)

[virtual]

Read the video . All steps independent of the file format will be performed, like testing for file readability etc.

Exceptions:

invalid_argument	invalid file format
ios_base::failure	a read error has occured [not supported by all libraries, so eventually {invalid_argument} instead]

virtual int VideoReader::readfmt

(

void

)

[protected, pure virtual]

Read different file formats (abstract). This is the method to be implemented for every video file format. It will be called by the {read ()} method.

Returns:
