Stream using libstreaming to VLC 2.2.4 exception

问题

I setup libstreaming to stream video from Android camera to VLC 2.2.4 on my macOS.

SharedPreferences.Editor editor = PreferenceManager.getDefaultSharedPreferences(context).edit();
editor.putString(RtspServer.KEY_PORT, String.valueOf(1777));
editor.apply();

SessionBuilder.getInstance()
                .setContext(context)
                .setCallback(this)
                .setAudioEncoder(SessionBuilder.AUDIO_NONE)
                .setVideoEncoder(SessionBuilder.VIDEO_H264)
                .setVideoQuality(new VideoQuality(640, 480, 15, 500000));

context.startService(new Intent(context, RtspServer.class));

Then I builded url bellow and opened it in VLC 2.2.4:

rtsp://172.xx.xx.67:1777?h264=500000-15-640-480

Then I received some logs on Android side:

Or shortly:

OPTIONS 200 -> DESCRIBE 200 -> SETUP 200 -> PLAY 200 -> TEARDOWN 200 
-> Error parsing CSeq (IllegalStateException: No successful match so far) 
- no method in the request

After successful connect (all steps above) I get exception in RtspServer.
As result I can't play the stream.
