Hi ,i am working on a projec Which i should start and stop manual record from Third party app and view recording status without viewing stream ,i tried to use milestone messages commands , but it didn't work ,so is there any other way to do that ?

If you look at VideoViewer sample, you will see how to record video from cameras. In the sample, there are start and stop recording buttons so it might be helpful.

If you want to see camera’s status, please explore Status Viewer sample. This sample might be helpful –
