New test method for SdpParser not passed

[biohot]

I created test method for SDP response of Garmin Virb 360 which not passed:

[TestMethod]
        public void Parse_TestDocumentWithVideoAndAudioTracksWithSameFmtNumber_ReturnsTwoTracks()
        {
            string testInput = "m=video 0 RTP/AVP 96\r\n" +
                               "a=control:rtsp://192.168.0.1/livePreviewStream/video\r\n" + 
                               "a=rtpmap:96 H264/90000\r\n" +
                               "a=fmtp:96 packetization-mode=1\r\n" +
                               "m=audio 0 RTP/AVP 96\r\n" +
                               "a=control:rtsp://192.168.0.1/livePreviewStream/audio48wyzx\r\n" + 
                               "a=rtpmap:96 mpeg4-generic/48000/4\r\n" +
                               "a=fmtp:96 streamType=5;profile-level-id=65;mode=AAC-hbr;config=11a0;sizeLength=13;indexLength=3;indexDeltaLength=3;constantDuration=1024\r\n";

            var testBytes = Encoding.ASCII.GetBytes(testInput);

            var parser = new SdpParser();
            IReadOnlyList<RtspMediaTrackInfo> tracks = parser.Parse(testBytes).Where(t => t is RtspMediaTrackInfo)
                .Cast<RtspMediaTrackInfo>().ToList();

            Assert.AreEqual(2, tracks.Count);
            RtspMediaTrackInfo videoTrack = tracks.First(t => t.Codec is VideoCodecInfo);
            Assert.AreEqual("rtsp://192.168.0.1/livePreviewStream/video", videoTrack.TrackName);
            Assert.AreEqual(90000, videoTrack.SamplesFrequency);
            RtspMediaTrackInfo audioTrack = tracks.First(t => t.Codec is AudioCodecInfo);
            Assert.AreEqual("rtsp://192.168.0.1/livePreviewStream/audio48wyzx", audioTrack.TrackName);
            Assert.AreEqual(48000, audioTrack.SamplesFrequency);
        }
