if I set RenderVideo and GetVideoRenderNativeSize this mode It’s required to set also FileOutput unfortunally.. I would like use VMR mode without capure the video in a file.. is it possible?
with ImageEnView1.IO.DShowParams do
begin
Disconnect;
w := VideoFormats[comboboxVideoFormat.ItemIndex].MaxWidth;
h := VideoFormats[comboboxVideoFormat.ItemIndex].MaxHeight;
SetVideoInput(comboboxVideoDevice.ItemIndex, 0, w, h); // set the second parameter if you have more than one camera with same name
// enable video and audio rendering
RenderVideo := true;
// set output file
FileOutput := “c:\video.avi”;
// connect to the video input
Connect;
GetVideoRenderNativeSize(w, h);
ImageEnView1.Proc.ImageResize(w, h);
Run;
end

Next version will have a new property in DShowParams (CaptureMode) which enables VMR also when FileOutput is empty.
You can try it now, just opening ieds.pas and in TIEDirectShow.StdConnect replace:
fBuilder.RenderStream(@PIN_CATEGORY_CAPTURE, @MEDIATYPE_Video, fCurVideoInput, inter, ppf);
with
fBuilder.RenderStream(@PIN_CATEGORY_PREVIEW, @MEDIATYPE_Video, fCurVideoInput, inter, ppf); |
