kirides / go-d3d Goto Github PK

I have no idea for this，please help me，thanks.

I have 2 monitors in extended mode.

1. 2560 x 1440 px
2. 1920 x 1080 px

Context: I'm running the mjpegstream example

If I just use any one of these then its fine but the program just fails when I have both connected and I try to record from the primary (index 0) monitor! This is the failure output -

Registering stream 0
Registering stream 1
Enabled PerMonitorAwareV2 DPI awareness.

exit status 2

But on non-primary monitor I get output like this -

The error occurs here ->

When encoding with e.g. ffmpeg, ffmpeg can handle the conversion, right? It'd be great if we could disable the conversion to RGBA.

Maybe it'd make sense to remove it from the library completely, because if someone wants to convert BGRA -> RGBA, it's just one line to add?

Just throwing around a couple ideas :)

Many thanks for building this lib!

I just wanted to thank you for making this library, that is all :)

May I ask how to capture the specified window, through the window handle or the specified area
