We have some purchased VH licences for rPI4 - recent server version and recent Raspbian(<14days) and latest client.
The application has two direct-show cameras (640x512) plus USB-6009 (National Instruments). The latter is low data volume DAQ.
Ehernet is a peer-peer cable. VH installed as service both places.
We see that the video is slower than with direct USB cables into the client which is probably to expect, but worse we see a fairly frequent freeze and lagging of the images. Freeze is now and then fatal and the application need to be restarted.
We tried to tweek the compression threshold but found no evidently better setting - probably a threshold of 584 is slightly better than default 384, but it is hard to tell.
Are there other handles we can try to turn to improve the smoothness and stability.
