用于快速集成七牛推流SDK 开发文档及API 七牛官方Demo

Application初始化

StreamingEnv.init(getApplicationContext());

参数初始化

            //编码设置 观众看到的视频画面
            //方式1 采用SDK带的默认参数
            mProfile = new StreamingProfile();
            mProfile.setVideoQuality(StreamingProfile.VIDEO_QUALITY_HIGH1)//Fps=30, Video Bitrate=1200
                    .setAudioQuality(StreamingProfile.AUDIO_QUALITY_MEDIUM2)//Audio Bitrate=48, Audio Sample Rate=44100
                    .setEncodingSizeLevel(StreamingProfile.VIDEO_ENCODING_HEIGHT_480)//16:9的时候是848 x 480
                    .setEncoderRCMode(StreamingProfile.EncoderRCModes.QUALITY_PRIORITY)//质量优先，实际的码率可能高于设置的码率
                    .setPublishUrl(mUrl);//设置推流地址

            //方式2 自定义编码参数
            /**
            // audio sample rate = 44100, audio bitrate = 48*1024 bps

            mMediaStreamingManager.prepare(camerasetting, mProfile);
            mMediaStreamingManager.setStreamingStateListener(this);
            mMediaStreamingManager.setStreamingSessionListener(this);
            mMediaStreamingManager.setStreamStatusCallback(this);
            mMediaStreamingManager.setAudioSourceCallback(this);

开始推流

prepare之后会在onStateChanged回调SDK状态，在READY时调用mMediaStreamingManager.startStreaming()即可

    case READY:
        Log.e(TAG, "READY");
        // start streaming when READY
        new Thread(new Runnable() {
            @Override
            public void run() {
                if (mMediaStreamingManager != null) {
                    mMediaStreamingManager.startStreaming();
                }
            }
        }).start();
        break;
