Sudden Error on a duplex stream

[ygreq]

Hi there, Martin! Sorry to bother you, but I am loosing my wits here. After a duplex communication between 2 Windows laptops worked without any issues, now I have errors even when trying to communicate simply and one of the laptops stops receiving video data. On PC2 I see the stream coming from PC1, but I cannot see the stream on PC1 coming from PC2. :/

I realized something was not right when I tried to check -s. (Please see the other post )

Any idea what is going on?
Thank you so much!!

It looks like no frame is captured from the DirectShow device indexed by 1 - would it be possible to paste output of -t dshow:help as for the audio in a parallel post? Thanks, MP

[ygreq]

Thank you, Martin! It seems the index changed for the camera. All because of the fact that I recently installed NDI on that specific device. I completely forgot that this might happen. All fixed now!
