// A pointer to this struct is passed to OMX_SetParameter or OMX_GetParameter

// when the extension index for the

// 'OMX.google.android.index.configureVideoTunnelMode' extension is  given.

// If the extension is supported then tunneled playback mode should be supported

// by the codec. If bTunneled is set to OMX_TRUE then the video decoder should

// operate in "tunneled" mode and output its decoded frames directly to the

// sink. In this case nAudioHwSync is the HW SYNC ID of the audio HAL Output

// stream to sync the video with. If bTunneled is set to OMX_FALSE, "tunneled"

// mode should be disabled and nAudioHwSync should be ignored.

// OMX_GetParameter is used to query tunneling configuration. bTunneled should

// return whether decoder is operating in tunneled mode, and if it is,

// pSidebandWindow should contain the codec allocated sideband window handle.
