Mediapool

Hallo,

I have a problem using the Media Pool.
I'd like to upload a file to mediaplayer1 od Mediaplayer 2 an I'd like to show tis with a key from the same player.
I'm looking for a example in c#.

Does anyone have an example for me to try this?

Thank you.
Jens

Hi Jens,

The closest we have to this is SDK sample SwitcherMediaPool, however it is written in C++, and it loads from a TGA file. I think you would be better to use .NET framework System.Drawing.Imaging library. The bitmap pixel format PixelFormat.Format32bppArgb [1] maps to Switcher pixel format bmdSwitcherPixelFormat8BitARGB.

You then have two options to get BitmapData into IBMDSwitcherFrame:

1. Create the IBMDSwitcherFrame object with IBMDSwitcherMediaPool::CreateFrame, the BitmapData should be locked and copied to the unmanaged buffer with IntPtr output by IBMDSwitcherFrame::GetBytes.[2][3]
2. If you want to prevent pixel buffer copy, then you can wrap the BitmapData in a class that implements IBMDSwitcherFrame. You should have a look at Desktop Video SDK sample StillsCSharp, to see this concept with the DeckLinkAPI (implementing IDeckLinkVideoFrame) [4]

Hi Cameron,

Thanks, I try it.
