I'm developing a simple app to automatically update Titles via http commands using VMix apis.
Each update changes the top margin, change stext, and then turns on overlay.

The problem I'm facing is that the first step's response time randomly ranges from 1-10 seconds, making this approach unreliable.
"http://192.168.11.107:8088/api/?Function=SetPanY&Input=6&Value=-0.3"
"http://192.168.11.107:8088/api/?Function=SetText&Input=6&Value=%EC%98%A8%20…
"http://192.168.11.107:8088/api/?Function=OverlayInput1In&Input=6"

Any idea why certain function takes this long, and is there a fix for this?
If there is a better way to adjust the top margin via api, I'm open to that too.

Thanks,

Jason

Just a thought, combining commands into one might help, dropping the number of requests required. Maybe not the full solution, only an "assist" in this case.

Looks to be only a pro/4k option however.

Hi Jason,

The delay is likely going to be on the client end. I have seen this happen where the client
does not correctly close the connection after each request.

If you build the app using .NET the WebClient does this automatically and has no delays, so that is what I would recommend.
Otherwise refer to the documentation for the method being used to see how to close the connection or handles correctly.

Regards,

Martin
