info

Microsoft does not provide a managed API for DirectShow.
The vcsharp_video_plyback_demo uses DirectShow.net library functions from the 3rd party DirectShowLib-2005.dll.
Documentation related to this library and its licence is given here.

DirectShow Registry Settings​

For the Colibri T20/T30 and Apalis T30 modules, the delay between the video stream and the audio stream can be adjusted to achieve synchronous playback.

[HKLM\Software\NVIDIA Corporation\NVDSHOW]
Nvdshow_AVSync_Offset=dword:400    ; delay in milliseconds

The default delay is 400ms.
