Hi All, it seems freezing of an NDI source is not uncommon but is universally irritating. I am hoping someone can save me some frustration here.

I have three to four NDI inputs into VMix, mixed into a 2x2 display. I am primarily using Kiloview U40 encoders being fed by Panasonic BGH-1 cameras. I am finding that occasionally the feed from one (sometimes both) encoders will freeze (as in the last frame is still shown). I have yet to determine a rhyme or reason for this, however lower resolutions seem so cause it less, but not prevent it altogether. If I power cycle the cameras so that the encoder 'no input' splash-screen comes up, the feed returns and everything is ok again.

It only seems to happen with the feed from these encoders, although they are providing the highest resolution feed. I also have an RSTP input which never has any problems. I also have a birdDog encoder which doesn't seem to do it, although I haven't used it so much as it does not have a pass-through network port and power (a great feature of the U40's!).

Does anyone have ideas on this one?

Cheers

Interestingly I have discovered that:
1. The problem occurs when running the client on the 1GbE wired network.
2. The problem occurs when running the client on a 1.2 gig wifi network (dedicated AP in close range).
3. When I connect the client by both the wired and wireless network the problem doesn't happen (at least got a full day without it presenting, where previously it'd happen with an hour or so).

Interestingly the total traffic is about 350 mb/s, when connected to both networks it splits it roughly evenly between the wired and wireless network. I don't know if this is the AP or the NDI protocol doing this as the wired network is piggy-backing off the AP.

Perhaps this points to a bandwidth issue, however it seems odd given the data stream is not utilising anywhere near capacity, and this network is temporarily setup and dedicated to the NDI feeds with a central 2.5 GbE switch and either CAT 5E or CAT 6 cabling. Thus I wonder if NDI somehow uses the two networks for redundancy? I'm on the verge of my knowledge here.

Keen to try out Dyno and see what it tells me.
