Example 1

Jump 50 seconds from beginning.

ZPlay C++ Class interface

TStreamTime pTime;
pTime.sec = 50; // we are using sec member of TStreamTime structure so we need tfSecond time format.
instance->Seek(tfSecond, &pTime, smFromBeginning);

C Style interface

TStreamTime pTime;
pTime.sec = 50; // we are using sec member of TStreamTime structure so we need tfSecond time format.
zplay_Seek(instance, tfSecond, &pTime, smFromBeginning);

Example 2

Jump 5 seconds forward from current position

ZPlay C++ Class interface

TStreamTime pTime;
pTime.sec = 5; // we are using sec member of TStreamTime structure so we need tfSecond time format.
instance->Seek(tfSecond, &pTime, smFromCurrentForward);

C Style interface

TStreamTime pTime;
pTime.sec = 5; // we are using sec member of TStreamTime structure so we need tfSecond time format.
zplay_Seek(instance, tfSecond, &pTime, smFromCurrentForward);
