We met a question is about combine mode.
Environment : Tiger Lake
Display specification : The chipset can support 4 monitor output.
Intel Media Center tool has support Clone, Extend and Combine mode for Muti-Display.
Question : Due to Combine mode only can select 4 (Monitors) x 1(Column) or 1(Row) x 4(Monitors)
How to use Intel Media SDK to set the Combine mode can support 2(Monitors) x 2(Row) for one Media content ?
I believe you are asking about rendering. Media SDK enables the hardware codec in the TigerLake integrated GPU to help the video processing; however, how to render the codec output is a rendering problem and this should be support by OS.
Can you specify what are you asking?
It would be better if you can post the platform hardware configuration, sometimes the platform also have discrete GPU which could make things complicated.
Platform : Intel Tiger Lake chipset, use internal GPU, no discrete GPU on it.
Output : 4 HDMI output
OS : Windows 10 2020H2
Drive : Intel PV version.
Display output setting : Intel Graphics Command Center
Due to Intel Graphics Command Center has support Combine mode (2~4 monitor combine to one display, like video wall) for display, But there only have 1 Rowx 4 Monitors or 1Colume x 4Monitors select items.
According customer request 4 HDMI output can combine to 2x2 display output, not only 1Row or 1Colume selection.
Intel Media SDK document, there can set output to display, but there has no detail information or command, how to set it can solve our problem ?
So are you asking how to use Media SDK to assign the output to 4 different output with HDMI?
I think this is out of our scope, Media SDK core function doesn't support rendering. We have rendering features in our sample, but it is for feature and performance purpose.
If you read the following document, it is not about rendering and not related to your question:
If you want to create a video wall, you can use our sample to create a video wall, here is an article that might help you:
There is also a recently thread discuss about this:
Hope this helps.
I am meaning the same video or picture output to 2row x 2colume mode with 4 HDMI Monitor.
sample picture : Can it output to 4 HDMI monitor and follow the blue number sequence ?
This is the first time I am aware of this mode, apology for the extra time to understand.
But this is basically still the rendering problem and out of the scope of Media SDK. For our sample code, we does have the rendering function by simply using the DirectX APIs. You can check how to use it in our sample.
Did you try this sample yet? I am assuming you must be in Windows to enable this mode.
