Q:mpc-hc cannot get the duration of video

S: To fix the condition part  follow this

 if(m_avFormat->duration == (int64_t)AV_NOPTS_VALUE || m_avFormat->duration < 0LL)

 

REFERENCE_TIME CLAVFDemuxer::GetDuration() const
{
  int64_t iLength = 0;
  if (m_avFormat->duration == (int64_t)AV_NOPTS_VALUE || m_avFormat->duration < 0LL) {
    // no duration is available for us
    // try to calculate it
    // TODO
    /*if (m_rtCurrent != Packet::INVALID_TIME && m_avFormat->file_size > 0 && m_avFormat->pb && m_avFormat->pb->pos > 0) {
    iLength = (((m_rtCurrent * m_avFormat->file_size) / m_avFormat->pb->pos) / 1000) & 0xFFFFFFFF;
    }*/
    DbgLog((LOG_ERROR, 1, TEXT("duration is not available")));
    return -1;
  } else {
    iLength = m_avFormat->duration;
  }
  return ConvertTimestampToRT(iLength, 1, AV_TIME_BASE, 0);
