Hi,
|
||
|
|
|
||
|
|
I'm trying to change the StillMotion sample to grab frames in a different
|
||
|
|
PixelFormat and resolution and I'm using the following code:
|
||
|
|
|
||
|
|
decompressedVideo.PixelBufferAttributes = NSDictionary.FromObjectsAndKeys(
|
||
|
|
new NSObject [] { new NSNumber(320), new NSNumber(240), new NSNumber(24)
|
||
|
|
},
|
||
|
|
new NSObject [] { new NSString("Width"), new NSString("Height"), new
|
||
|
|
NSString("PixelFormatType")});
|
||
|
|
|
||
|
|
|
||
|
|
This code when used in the original Cocoa StillMotion sample works perfectly
|
||
|
|
and changes the resolution of the grabbed frames to 320x240 and the pixel
|
||
|
|
format to 24 bits RGB.
|
||
|
|
|
||
|
|
Am I doing something wrong or there is some problem in the biding? As you
|
||
|
|
can for the pixelFormat options the constants available in Cocoa are not
|
||
|
|
available in MonoMac is this a problem?
|
||
|
|
|
||
|
|
In the same sample I'm trying to convert CVImageBuffer to
|
||
|
|
System.Drawing.Bitmap instead of a NSImage,
|
||
|
|
I'm using the following code
|
||
|
|
|
||
|
|
delegate(object sender, QTCaptureVideoFrameEventArgs e) {
|
||
|
|
currentImage = e.VideoFrame;
|
||
|
|
|
||
|
|
if (currentImage == null)
|
||
|
|
return;
|
||
|
|
|
||
|
|
var img = CIImage.FromImageBuffer (currentImage);
|
||
|
|
NSBitmapImageRep imageRep = new NSBitmapImageRep(img);
|
||
|
|
|
||
|
|
var bitmap = new Bitmap(imageRep.PixelsWide, imageRep.PixelsHigh,
|
||
|
|
imageRep.BytesPerRow,
|
||
|
|
PixelFormat.Format24bppRgb,
|
||
|
|
imageRep.BitmapData);
|
||
|
|
// Debug: Save the image as a JPEG.
|
||
|
|
bitmap.Save("/a.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
|
||
|
|
};
|
||
|
|
|
||
|
|
|
||
|
|
Is this the best/fastest way of doing it? Is there any other method?
|
||
|
|
|
||
|
|
Thanks,
|
||
|
|
|
||
|
|
