Welcome to Android Central! What's the model number of the camera, and which phone are you using with it? Are you using an app from Dahua to view the stream?
@B. Diddy it's not related to the camera's firmware as we get the stream well in iOS & Windows only the issue is with android(In QT5 framework it's working fine only after migrating to QT6 we are facing this issue).
But it could be something to do with its compatibility or interoperability with Android, which could still be due to something in its firmware. Regardless, it's still worth reaching out to their support team.
