Hi,
I wrote a directshow filter using libavcodec to play MPEG 1/2.
For MPEG 2, it's OK. But for MPEG 1, it flickers all the time.
Maybe there are some differences in timestamping between MPEG 1 and MPEG 2?
Thanks in advance,
Pathos
REFERENCE_TIME rtStart, rtStop;
pIn->GetTime(&rtStart, &rtStop);
if (!rtLastTime || (pIn->IsDiscontinuity() == S_OK) || rtStart < 0)
{
if (rtStart > 0 )
rtLastTime = rtStart;
else
rtLastTime += rtFrameTime;
}
REFERENCE_TIME endtime = rtLastTime + rtFrameTime;
pOut->SetTime(&rtLastTime, &endtime);
rtLastTime = endtime;
hr = m_pOutput->Deliver(pOut);
