// Converts YUV video frames to RGB format and stores the results in the
// provided mailbox. The caller of functions in this class maintains ownership
// of the destination mailbox. VideoFrames that wrap external textures can be
// I420 or NV12 format. Automatically handles upload of CPU memory backed
// VideoFrames in I420 format. Converting CPU backed VideoFrames requires
// creation of shared images to upload the frame to the GPU where the conversion
// takes place. This will not perform any color space conversion besides the
// YUV to RGB conversion (it will ignore the color space of the SharedImage
// backing the destination mailbox).
// IMPORTANT: Callers of this function can cache this class and call
// ConvertYUVVideoFrame() to prevent repeated creation/deletion of shared
// images.
