... The DAL supports Null Values (both integer and real). For objects (i.e. arrays or columns) containing integer data, it is possible to define a null value. A data value is then is considered null if it is equal to the object's null value. Integer data containing null values may be operated on safely i.e. arithmetic operations. ... Real data containing null values must be treated carefully i.e. testing for nullity before carrying out any further operations. ...

... One of these factors is how the client application uses VDPAU; i.e. the number of surfaces allocated for buffering, order of operations, etc. ... At a bare minimum, the application must allocate one video surface for each reference frame that the stream can use (2 for MPEG or VC-1, a variable stream-dependent number for H.264) plus one surface for the picture currently being decoded. However, if this minimum number of surfaces is used, performance may be poor. ... Performance Levels . ...
