BusyWaitVideoSync Class Reference
#include <vsync.h>
Inheritance diagram for BusyWaitVideoSync:
Detailed Description
Video synchronization classes employing usleep() and busy-waits.Non-phase-maintaining. There may occasionally be short periods of jitter that eventually go away.
This method does not maintain phase and uses the most CPU of any of the VSync methods. But it is the catch-all fallback algorithm, TryInit(void) always succeeds.

| bool BusyWaitVideoSync::TryInit | ( | void | ) | [virtual] |
| void BusyWaitVideoSync::WaitForFrame | ( | int | sync_delay | ) | [virtual] |
Waits for next a frame or field.
Start(void), WaitForFrame(void), and Stop(void) should always be called from same thread, to prevent bad interactions with pthreads.
- Parameters:
-
sync_delay time until the desired frame or field
- See also:
- CalcDelay(void), KeepPhase(void)
Implements VideoSync.
