Current Behavior

Hello , i'am implement for an Camera -Company Microscopy -Cameras an DirectX (Show) (*.ds) camera driver, there run in all Programs like skype vlc dx-graph and many other application nice.

But i'am shortly add this driver to OBS Video-Source, i'am got not an SizeBox in OBS PreView for this device, and i got no images. If i'am add VLC-Virtual-Camera then i got this Sizebox and images, what's also wrong with my own DX -Show Filter in OBS - Studio ?

Error case is :
No images are Shown in OBS Studio but driver accepted. (My DShow (
.ds) Driver ) has all abilities to run normal).
*

Thank you much for any suggestion

Research direction

The report concerns the OBS Video-Source and a DirectShow camera driver, but names no files, tests, logs, or reproducible steps. Start by reproducing the missing preview image and size box with the reported driver, then compare the behavior with the VLC virtual camera and document a confirmed cause and testable fix.
