AVFoundation video capture.
I am new bie to MAC AVFoundation programming.
I am trying to capture video from camera with a specific resolution, but I am not understanding about configuring video device with specific video dimension like 320x240.
In one way, I am setting as following code snippet. But even though I am setting with 320x240, it is capturing at 320x176 resolution. I am not understanding which are the APIs to use.
Please suggest proper way to handle this Media capture. Also provide me links, if any documentation or samples.
NSDictionary* captureDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithDouble:176], (id)kCVPixelBufferWidthKey,
[NSNumber numberWithDouble:144], (id)kCVPixelBufferHeightKey,
// Specify the pixel format
vid_out.videoSettings = captureDictionary;

AVFoundation video capture at specific resolution.
I explored and understood video capture using AVFoundation. It is allowing me to set preset only for fixed resolutions as described in session presets. But cameras will support different resolutions other than these preset resolutions like 640x360. I am trying to capture at this resolution, but this is not working for me. Please tell me how I can set format to capture video at this resolution.
Thanks and Regards,
