Yes, i think you're right.
I've changed it to Connect, and also tried to swap pings, no success:
original:
result = m_pOutputPin->vt->ReceiveConnection(m_pOutputPin,
m_pOurOutput,
m_pDestType);
fails.
v1:
result = m_pOurOutput->vt->ReceiveConnection(m_pOurOutput,
m_pOutputPin,
m_pDestType);
retusn 0, but sig11 in decoder
v2:
result = m_pOutputPin->vt->Connect(m_pOutputPin,
m_pOurOutput,
m_pDestType);
fail same way as original
v3:
result = m_pOurOutput->vt->Connect(m_pOurOutput,
m_pOutputPin,
m_pDestType);
return 0 but sig11 same way as v1
btw, in COutputPin_Connect():
//return E_NOTIMPL;
return 0;// XXXXXXXXXXXXX CHECKME XXXXXXXXXXXXXXX
// if I put return 0; here, it crashes
so it seems to be unimplemented :(((
