If I look at stack traces which concern LAVFDShowSplitter I see :
- for CLAVFOutPut Pin Video thread :
Code:
LAVFDShowSplitter.ax!CBaseOutputPin::GetDeliveryBuffer(IMediaSample * * ppSample, __int64 * pStartTime, __int64 * pEndTime, unsigned long dwFlags) Ligne 2654 + 0x2c octets C++
02de6c50()
LAVFDShowSplitter.ax!CLAVFOutputPin::ThreadProc() Ligne 275 + 0x23 octets C++
LAVFDShowSplitter.ax!CAMThread::InitialThreadProc(void * pv) Ligne 123 + 0xe octets C++
- for CLAVFOutPut Pin Audio thread :
Code:
LAVFDShowSplitter.ax!CBaseOutputPin::GetDeliveryBuffer(IMediaSample * * ppSample, __int64 * pStartTime, __int64 * pEndTime, unsigned long dwFlags) Ligne 2654 + 0x2c octets C++
02de7050()
LAVFDShowSplitter.ax!CLAVFOutputPin::ThreadProc() Ligne 275 + 0x23 octets C++
LAVFDShowSplitter.ax!CAMThread::InitialThreadProc(void * pv) Ligne 123 + 0xe octets C++
- demuxer thread seems to sleep(1) because the queue is full.
In fact both Output Pin threads are waiting for "m_pAllocator->GetBuffer(ppSample,pStartTime,pEndTime,dwFlags);" to return but it never does ...
Does somebody have an idea about what could cause this ?
Thanks in advance ! |
I am still trying to understand this so I compiled a debug version of MPC-HC and here what I got :

It seems that the problem happens after the samples have been decoded but I don't know how to find what happens exactly ...
