setOSD(): position can take effect, but plaintext does not

[zhengguoxin]

A very strange problem, when using

setOSD (OSDToken, videoSourceConfigurationToken, plaintext, position)

the setting is successful, and the OSD position of the camera has also changed, but plaintext remains unchanged. However, when using getOSD, it can be found that the plaintext has indeed changed.

I used different cameras and NVR tests, but they were all like this. Do you need any other settings after calling setOSD?

are you trying to change it to a simple camera related to a single ip address? i tried to apply changes to dvrs with multiples cameras with no luck
