[Android.Runtime.Register("queueSecureInputBuffer", "(IILandroid/media/MediaCodec$CryptoInfo;JI)V", "")]
public void QueueSecureInputBuffer (int index, int offset, Android.Media.MediaCodec.CryptoInfo info, long presentationTimeUs, Android.Media.MediaCodecBufferFlags flags);
[<Android.Runtime.Register("queueSecureInputBuffer", "(IILandroid/media/MediaCodec$CryptoInfo;JI)V", "")>]
member this.QueueSecureInputBuffer : int * int * Android.Media.MediaCodec.CryptoInfo * int64 * Android.Media.MediaCodecBufferFlags -> unit
