Code:

int64_t CVideoReferenceClock::GetTime(bool interpolated /* = true*/)
    ...
    return CurrentHostCounter() + m_ClockOffset;

I add log find that m_ClockOffset is always changing, and can not find where the m_ClockOffset is changed.
There are only two places can change the m_ClockOffset in the source code.
1.void CVideoReferenceClock::Start()
But can only be run once.
2.void CVideoReferenceClock:rocess()
But is not run.

Who can tell me where the m_ClockOffset is changed?
Thanks!

Process() runs on a separate thread. Start() starts that thread.

Could you tell me where is the code?

[ironic_monkey]

xbmc/thread/Thread.h is the base class

Process() runs on a separate thread. Start() starts that thread.

Process() is not run because I add log in it and no log was showing.

[ironic_monkey]

then the cause is likely that you have not enabled sync to display. in ::Start it sets the reference value, THEN checks if it should start the thread. so you would see a changing value, just not very often, and it would not run Process(). in any case, crank out the debugger i will tell you exactly what is going on..

I compiled the kodi to android apk.
How to crank out the debugger ?I add an ERROR level log in the Process()'s while ,it's not showing.But m_ClockOffset's value often change in the CVideoReferenceClock::GetTime(bool interpolated /* = true*/)

Add a printout in the start method then?

[ironic_monkey]

You should be able to debug using eg ndk-gdb.

Add a printout in the start method then?

Code:

void CVideoReferenceClock::Start()
{
  CLog::LogF(LOGERROR, "CVideoReferenceClock::Start()-------------");
  m_ClockOffset = CurrentHostCounter();
  if(CServiceBroker::GetSettings().GetBool(CSettings::SETTING_VIDEOPLAYER_USEDISPLAYASCLOCK) && !IsRunning()){
      CLog::LogF(LOGERROR, "CVideoReferenceClock::create()-------------");
        Create();
  }
}

The above code , can only showing the "CVideoReferenceClock::Start()-------------" log,and no "CVideoReferenceClock::create()-------------" log.

which means i perfectly described what happens above no?

@ironic_monkey
Yes,the Process() is not running.
But the ::Start only run once.
But the m_ClockOffset's value often changs,so where changes it?

Thats unusable please post your log snippets via pastebin.com - its totally screwed up with no line endings in tapatalk for example ...

@Memphiz
I am sorry the log is too large.I have put it on the google drive.
https://drive.google.com/file/d/0ByZyety...sp=sharing

Code:

01-08 06:28:45.190 V/Kodi    ( 4344): Debug Print: PrepareNextRender: -------tclogkodi -----CRenderManager::PrepareNextRender-------m_lateframes=551

From the log,I see that m_lateframes's value is 551.
So when I play a video is discontinuity,then I track to the m_ClockOffset's value as above.
