Question

Dshow bridge crash is top crash in our application

AndyWei 6

We find that the crash is the top crash in our application. We use DShow api to capture video in our application.Before crash,our application are capturing video and we did not invove any Dshow API.

We found that if the registry \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_046D&PID_0891&MI_00\6&243bf7f8&0&0000\Device Parameters\EnableDshowRedirection is 1, Dshow will load mfksproxy.dll ,and use Media Foundation to capture video.

if EnableDshowRedirection is 0,Dshow will load ksproxy.ax, and use Dshow native api to capture video.

I want to ask.

how can we solve the crash?
how can we disable Dshow bridge use DShow API or other API?

Could you please show a minimal, reproducible sample without private information? OR Can you reproduce it using one DirectShow Sample?
