Member Function Documentation

void SimpleFramedSource::deliverFrame

(

)

This function is called when new frame data is available from the device.

This function is called when new frame data is available from the device. We deliver this data by copying it to the 'downstream' object, using the following parameters (class members): **** 'in' parameters (these should not be modified by this function): ** fTo: The frame data is copied to this address. (Note that the variable "fTo" is not modified. Instead, the frame data is copied to the address pointed to by "fTo".) ** fMaxSize: This is the maximum number of bytes that can be copied (If the actual frame is larger than this, then it should be truncated, and "fNumTruncatedBytes" set accordingly.) ***** 'out' parameters (these are modified by this function): ** fFrameSize: Should be set to the delivered frame size (<= fMaxSize). ** fNumTruncatedBytes: Should be set iff the delivered frame would have been bigger than "fMaxSize", in which case it's set to the number of bytes that have been omitted. ** fPresentationTime: Should be set to the frame's presentation time (seconds, microseconds). This time must be aligned with 'wall-clock time' -i.e., the time that you would get by calling "gettimeofday()". ** fDurationInMicroseconds: Should be set to the frame's duration, if known. If, however, the device is a 'live source' (e.g., encoded from a camera or microphone), then we probably don't need to set this variable, because -in this case- data will never arrive 'early'.
