示例1: CaptureImageCompletedEventArgs
void
CaptureSource::CaptureImageReportSample (gint64 sampleTime, gint64 frameDuration, guint8 *sampleData, int sampleDataLength)
{
SetCurrentDeployment ();
d(printf ("CaptureSource::CaptureImageReportSample (%lld, %lld, %d\n", (long long) sampleTime, (long long) frameDuration, sampleDataLength));
if (HasHandlers (CaptureSource::CaptureImageCompletedEvent)) {
BitmapImage *source = MoonUnmanagedFactory::CreateBitmapImage ();
source->SetPixelWidth (capture_format->width);
source->SetPixelHeight (capture_format->height);
source->SetBitmapData (sampleData, false);
source->Invalidate (); // causes the BitmapSource to create its image_surface
CaptureImageCompletedEventArgs *args = new CaptureImageCompletedEventArgs (NULL);
args->EnsureManagedPeer ();
args->SetSource (source);
source->unref ();
Emit (CaptureSource::CaptureImageCompletedEvent, args);
}
// if we started the pal device strictly for an image capture
// (or kept it running after the user had called
// CaptureSource::Stop), stop it now.
if (current_state != CaptureSource::Started) {
VideoCaptureDevice *video_device = GetVideoCaptureDevice ();
video_device->Stop();
}
