tx直播sdk初见

1.申请Licence,获得 LICENSEURL 和 LICENSEURLKEY

2.创建应用,获得 SDKAPPID 和 SECRETKEY

3.配置 PUSH_DOMAIN (推流域名,tx后台自动生成), PLAY_DOMAIN(拉流域名,要有自己的域名),LIVE_URL_KEY(推流鉴权使用到的key,必须配置)

4.推流url

pushUrl = RTMP + GenerateTestUserSig.PUSH_DOMAIN + File.separator + APP_NAME + File.separator + streamId
                    + GenerateTestUserSig.getSafeUrl(streamId);


public static String getSafeUrl(String streamName) {
        long txTime = System.currentTimeMillis() / 1000 + 60 * 60;
        String input = new StringBuilder().append(LIVE_URL_KEY).append(streamName)
                .append(Long.toHexString(txTime).toUpperCase()).toString();
        String txSecret = null;
        try {
            MessageDigest messageDigest = MessageDigest.getInstance("MD5");
            txSecret = byteArrayToHexString(messageDigest.digest(input.getBytes("UTF-8")));
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return new StringBuilder().append("?txSecret=").append(txSecret).append("&").append("txTime=")
                .append(Long.toHexString(txTime).toUpperCase()).toString();
    }

5.开始推流

int ret = mLivePusher.startPush(pushUrl);

6.如果是录屏推流,注意权限和前台服务

<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

android:foregroundServiceType="mediaProjection"
android:exported="true"

public void startMediaProjectionService(Activity activity){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            Intent intent = new Intent(activity,MyCaptureService.class);
            startForegroundService(intent);
        }
    }

    public void stopMediaProjectionService(Activity activity){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
            Intent intent = new Intent(activity,MyCaptureService.class);
            stopService(intent);
        }
    }

//service里别忘了
startForeground(R.drawable.ic_launcher, notification); 

7.拉流url

public static String generatePlayUrl(String streamId, String userId, int type) {
        String playUrl = "";
        if (type == 0) {
            playUrl = RTMP + GenerateTestUserSig.PLAY_DOMAIN + File.separator + APP_NAME + File.separator + streamId;
        } else if (type == 1) {
            playUrl = HTTP + GenerateTestUserSig.PLAY_DOMAIN + File.separator + APP_NAME + File.separator + streamId
                    + ".flv";
        } else if (type == 2) {
            playUrl = HTTP + GenerateTestUserSig.PLAY_DOMAIN + File.separator + APP_NAME + File.separator + streamId
                    + ".m3u8";
        } else if (type == 3) {
            playUrl =
                    TRTC + TRTC_DOMAIN + "/play/" + streamId + "?sdkappid=" + GenerateTestUserSig.SDKAPPID + "&userid="
                            + userId + "&usersig=" + GenerateTestUserSig.genTestUserSig(userId);
        } else if (type == 4) {
            playUrl = WEBRTC + GenerateTestUserSig.PLAY_DOMAIN + File.separator + APP_NAME + File.separator + streamId;
        }
        return playUrl;
    }

7.开始拉流

int result = mLivePlayer.startLivePlay(playURL);
