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

// '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.
