QuercusVL Programming Manual
Returns true if the object contains valid information about an image, and false if invalid.
Some methods, may sometimes, return void images. In C, this behaviour is detected as
its value will be “0”. In C++, however, this method is necessary because the object, as
it is not a pointer, would always be valid.

Location
C++:
int Location(char* pBuffer, int bufferLen)
C:
int VL_Video_get_Location(int h, char* pBuffer, int maxSize)
provides the absolute path of the video file in the unit, at text string “pBuffer”, ending
with character \0. You need to set the buffer size at “maxSize”
Returns the number of characters in the string
In C, the parameter “h” is a handler of video (Video).
●
IniTimestamp
C++:
Timestamp get_IniTimestamp()
C:
Does not exist.
In C++, returns the time stamp where the unit started the video capture
In C, there is no representation of “TimeStamp“ class, but methods to directly access to
its properties:
