hi,guys
what's up!
there are some problems in my recent project development.
i use averEZcapture video card in my project,and i want set the video size 320X240 on the
preview pin and 768*576 on the capture pin!
but i can't preview the video well(i render it onto the videorender filter),it's quite freeze.
but the capture pin work well(i render it onto the null render filter,and it can grabber the sample with 768*576);
i just want to it's possible to render output different video size on preview pin and capture
pin,if can,how ?
thank u!
and my source code just like below :
Graphabuilder.findinterface(@PIN_CATEGORY_CAPTURE,........);captureconfig
//get the Iamstreamconfig on the capture pin
graphabuilder.findinterface(@PIN_CATEGORY_Preview..........);/previewconfig
//get the Iamstreamconfig on the Preview pin
// set the am_media_type each
captureconfig.setformat();
previewconfig.setformat();
