Synopsis:
[Bug 8335] High CPU load on Pause Playback Status
Overview:
Currently when we play any a/v file in Linux, and during playback we do
a PAUSE, CPU usage jumps to 100%. During the PAUSE, the audio thread
should be waiting for the data, but it was not happening since we were
not initializing the event and due to this although we are going to
CHelixEvent::Wait(UINT32 ulTimeoutPeriod) in file chxthread.cpp , but
inside this function, we are always getting m_pEvent as NULL so we never
reaches HXUnixEvent::Wait(). Inside audunix.cpp, we are doing
m_pAvailableDataEvent->SignalEvent(); but are not calling Init on
m_pAvailableDataEvent to initialize the events.
So, calling Init on m_pAvailableDataEvent solves the problem.
