Due to the comment here ([D3d11videosink sync](https://discourse.gstreamer.org/t/d3d11videosink-sync/299)) I have been trying to use d3d11overlay element but I have some linking problems with 1.23.2 release. Example launchline:  
\gst-launch-1.0.exe uridecodebin uri=rtsp://caminlocalnetwork ! queue2 ! d3d11overlay ! queue2 ! videocrop ! d3d11videosink

0:00:02.556232700 14688 0000022F919FE5C0 WARN basesrc gstbasesrc.c:3175:gst\_base\_src\_loop: error: Internal data stream error.  
0:00:02.562956200 14688 0000022F919FE5C0 WARN basesrc gstbasesrc.c:3175:gst\_base\_src\_loop: error: streaming stopped, reason not-linked (-1)

if I remove d3d11overlay then it works… I couldn’t find the reason of this linking error, I tried increasing debug level but beyond 3 doesn’t really mean anything to me. Any help about debugging this is greatly appreciated…

d3d11overlay supports only RGBA or BGRA format. You need to configure `d3d11convert` (or `d3d11colorconvert`) in front of `d3d11overlay` like

`... ! d3d11upload ! d3d11convert ! d3d11overlay ! ... `
