I am using the LibVLCSharp library to play an m3u8 file. (TS encrypted videos)
I want to use a string (text of the same file) instead of m3u8 file to the code for more security.
{In fact, I encrypt the m3u8 file with static key and save it on hard disk. I want to decrypt it in the program and play the m3u8 file without saving decrypted file on hard disk.}

Acceptable code for the library

            LibVLC _libVLC = new LibVLC("");
            _libVLC.SetLogFile("log1.txt");

            videoView1.MediaPlayer = new MediaPlayer(_libVLC);

            Media plist = new Media(_libVLC, "vi/file.m3u8", FromType.FromPath);
            videoView1.MediaPlayer.Play(plist);

The code I want does not work

string s = "#EXTM3Urn
            #EXT-X-VERSION:3rn
            #EXT-X-TARGETDURATION:17rn
            #EXT-X-MEDIA-SEQUENCE:0rn
            #EXT-X-PLAYLIST-TYPE:VODrn
            #EXT-X-KEY:METHOD=AES-128,URI="key",IV=0x00000000000000000000000000000000rn
            #EXTINF:16.666667,rn
            file0.tsrn
            #EXTINF:8.333333,rn
            file1.tsrn
            #EXTINF:8.333333,rn
            file2.tsrn
            #EXTINF:9.133333,rn
            file3.tsrn
            #EXT-X-ENDLIST";

    LibVLC _libVLC = new LibVLC("");
    _libVLC.SetLogFile("log1.txt");

    videoView1.MediaPlayer = new MediaPlayer(_libVLC);

    byte[] byteArray = Encoding.UTF8.GetBytes(s);
    Stream stream = new MemoryStream(byteArray);
    MediaInput aa = new StreamMediaInput(stream);

    Media plist = new Media(_libVLC, aa, ""); 
    videoView1.MediaPlayer.Play(plist);

play m3u8 video with LibVLCSharp form a string.
