DECKLINK DUO2 get bitmap data

Hello, I'm working with decklink duo 2 on C# net core 6. I'm trying to get bitmap data for image processing , but it doesn't work. Please help me!

public void InputVideoFrameArrived(object sender, DeckLinkDeviceInputVideoFrameEventArgs e)
{
if (e.videoFrame.GetFlags().HasFlag(_BMDFrameFlags.bmdFrameHasNoInputSource))
return;

FPSCount++;
double T = DateTime.Now.Subtract(TimeStart).TotalMilliseconds;
if (T > 1000)
{
Debug.WriteLine("FPS: " + (int)(FPSCount * 1000.0f / T));
TimeStart = DateTime.Now;
FPSCount = 0;
}


byte[] mediaFrameBuffer = { };
IntPtr srcPtr;
e.videoFrame.GetBytes(out srcPtr);
System.Runtime.InteropServices.Marshal.Copy(srcPtr, mediaFrameBuffer, 0, e.videoFrame.GetHeight() * e.videoFrame.GetWidth());
System.Runtime.InteropServices.Marshal.ReleaseComObject(e.videoFrame);

Bitmap bmp;
using (var ms = new MemoryStream(mediaFrameBuffer))
{
bmp = new Bitmap(ms);
}
}

Help me, please!

Perhaps try to describe a bit more, what are you doing, and what exactly does not work ? Your app crashes, you get only black, etc.

Hi Le Thi Hang,

Did you try running with the StillCSharp SDK sample? This sample performs the necessary steps to get the Bitmap from the output IntPtr from IDeckLinkVideoFrame::GetBytes on the captured frame object.

I have also tested capturing the Bitmap after update to .NET Core 6 with Upgrade Assistant. Ref https://learn.microsoft.com/en-us/dotne ... t-overview.

Hi Cameron, I did try running with the StillCSharp SDK sample. When running on .net framwork it is normal, but when running on .net core 6, I get an error. Error in ConvertFrame function.
