// This test verifies a typical path for a MailboxVideoFrameConverter configured
// to receive frames that don't need to be unwrapped. This mode is used for
// out-of-process video decoding. The MailboxVideoFrameConverter is fed two
// GpuMemoryBuffer frames and after it outputs the two corresponding Mailbox
// frames, we verify that the MailboxVideoFrameConverter can handle those frames
// being released by the client. Note that in this mode, SharedImages are not
// expected to be re-used because in out-of-process video decoding, we always
// create a new frame with a unique ID for every GpuMemoryBuffer we receive
// from the video decoder process.
