Unable to record zoom meeting due to exception "Value to add was out of range. Parameter name: value"


I have written below code to start recording.
ValueType starttimestamp = (DateTime.UtcNow - new DateTime(1970, 1, 1)).TotalSeconds;

sDKError = ZOOM_SDK_DOTNET_WRAP.CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().GetMeetingRecordingController().StartRecording(ref starttimestamp);

In the code above at line 1 throws exception “System.ArgumentOutOfRangeException: Value to add was out of range.
Parameter name: value
at System.DateTime.Add(Double value, Int32 scale)
at ZOOM_SDK_DOTNET_WRAP.?A0xe11cbd8a.time_t2DateTime(Int64 date)

at BBZoomMeet.frmBBZoomMeet.DoZoomMeetingAction(String MeetingInfo) in C:\VarshaProjects\TestProjects\BBZoomMeet\frmBBZoomMeet.cs:line 959”

Hi @arvind.sonar,

Are you able to reproduce this issue using the native C++ SDK? As mentioned in our documentation, the C# wrapper is provided as a reference and is not actively supported. As a result, we are only able to assist with this if you are able to reproduce with the C++ SDK directly. I have not been able to reproduce, so please let me know if you are able and we can investigate further.


I can reproduce the issue using native c++ SDK. Plz find the screenshot attached

plz suggest the solution to fix the exception.

Hi @arvind.sonar,

The screenshot you’ve provided is still using the C# wrapper. Using the C++ SDK natively means that you are using it directly in a C++ environment.


How can I check that

Hi @arvind.sonar,

You can test in the C++ sample app by downloading the Windows SDK from the Marketplace.


I am not getting how to do this. Plz help.

Hi @arvind.sonar,

Please see our documentation for information on how to download the SDK.
