Member Function Documentation

GetCompression()

uint32_t PlayerCc::CameraProxy::GetCompression ( ) const

inline

What is the compression type? Currently supported compression types are:

• PLAYER_CAMERA_COMPRESS_RAW
• PLAYER_CAMERA_COMPRESS_JPEG

References playerc_camera_t::compression.

GetFormat()

uint32_t PlayerCc::CameraProxy::GetFormat ( ) const

inline

Image format Possible values include.

• PLAYER_CAMERA_FORMAT_MONO8
• PLAYER_CAMERA_FORMAT_MONO16
• PLAYER_CAMERA_FORMAT_RGB565
• PLAYER_CAMERA_FORMAT_RGB888

References playerc_camera_t::format.

GetImage()

void PlayerCc::CameraProxy::GetImage ( uint8_t *  aImage ) const

inline

Image data This function copies the image data into the data buffer aImage.

The buffer should be allocated according to the width, height, and depth of the image. The size can be found by calling GetImageSize().

References playerc_camera_t::image, and playerc_camera_t::image_count.

SaveFrame()

void PlayerCc::CameraProxy::SaveFrame	(	const std::string	aPrefix,
		uint32_t	aWidth = 4
	)

Save the frame.

• aPrefix is the string prefix to name the image.
• aWidth is the number of 0s to pad the image numbering with.
