使用libstreaming流到VLC 2.2.4异常

Question

我设置 libstreaming 将视频从Android摄像头流式传输到我的macOS上的VLC 2.2.4。

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));

然后我在下面建造了url并在VLC 2.2.4中打开它：

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

然后我在Android端收到了一些日志：

或者很快：

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

成功连接（上述所有步骤）后，我在 RtspServer 中获得例外 结果我无法播放流。

以下是官方示例spydroid-ipcamera的日志（从VLC 2.2.4连接）：

!!!它适用于VLC 1.1.5：
