How to select video input from capture board? |
|
|
I am encoding live audio and video using WMEncoder SDK and Digital Rapids's
DRC-1500 encoding board.
I want to select video-input to 's-video'.
It seems that there is no API in WMEncoder SDK to do this.
Could anybody tell me how I can do this through programming?

Additinally, I am making the encoder service, so using the property-page is
impossible.
I must select 's-video' without user-interface.

Have you tried selecting the S-video feed via any app that DR supply? Google
for AMCAP - if you can get the S-Video working with that - it should force
WME over to that signal...

You need to get the IAMCrossbar interface on the capture filter and
enumerate the pins. Once you have identified an input to output pin route
you can save those pin numbers for future use with that card. If the
driver is written correctly you should be able to identify s-video by the
pin having the type PhysConn_Video_SVideo.
Refer to the DirectShow documentation for IAMCrossbar and "Working with
Crossbars" as WME uses DirectShow as the front end. |
