我尝试使用Live555将视频文件（h264原始流）从Android设备流式传输到VLC。我的本机代码基于testh264streamer示例，它在Ubuntu上运行正常
但是，当我尝试在Android上启动流式传输时，它无效。视频文件成功打开，客户端收到一些软件包（我跟随Wireshark），但VLC没有显示任何内容。
我想问题是Java和C ++之间的联系，所以这里是我的Java代码，它调用本地流方法：
public class LiveStreamer implements Runnable {
private static final String LOG_TAG = LiveStreamer.class.getSimpleName();
private Context context;
private String fileName;
private FileDescriptor fileDescriptor;
public LiveStreamer(Context context, String fileName) {
this.context = context;
this.fileName = fileName;
this.prepare();
}
private void prepare() {
try {
fileDescriptor = prepareStream(fileName, fileDescriptor);
} catch (IOException e) {
e.printStackTrace();
}
}
public String getFileName() {
return fileName;
}
public FileDescriptor getFileDescriptor() {
return fileDescriptor;
}
private native void stream(String ipAdress);
private native FileDescriptor prepareStream(String file, FileDescriptor fd)
throws IOException;
@Override
public void run() {
Log.d(LOG_TAG, "Start streaming ...");
String ipAddress = NetworkUtilities.getWifiIpAddress(context);
if (fileDescriptor != null) {
stream(ipAddress);
}
Log.d(LOG_TAG, "Stopp streaming ...");
}
}
我的原生代码：
JNIEXPORT void JNICALL Java_[PACKAGE_NAME]_LiveStreamer_stream(
JNIEnv *env, jobject obj, jstring ipAddress) {
const char* c_ipaddress = env->GetStringUTFChars(ipAddress, false);
jclass streamClazz = env->GetObjectClass(obj);
jclass exceptionClazz = env->FindClass("java/lang/RuntimeException");
if (streamClazz == NULL || exceptionClazz == NULL) {
return;
}
if (videoFile == NULL) {
return;
}
// setting up the usage environment
TaskScheduler *scheduler = BasicTaskScheduler::createNew();
uenv = BasicUsageEnvironment::createNew(*scheduler);
// Creating groupsocks
struct in_addr destinationAddress;
destinationAddress.s_addr = chooseRandomIPv4SSMAddress(*uenv);
const unsigned short rtpPortNum = 18888;
const unsigned short rtcpPortNum = rtpPortNum + 1;
const unsigned char ttl = 255;
const Port rtpPort(rtpPortNum);
const Port rtcpPort(rtcpPortNum);
Groupsock rtpGroupsockVideo(*uenv, destinationAddress, rtpPort, ttl);
Groupsock rtcpGroupsockVideo(*uenv, destinationAddress, rtcpPort, ttl);
rtpGroupsockVideo.multicastSendOnly();
rtcpGroupsockVideo.multicastSendOnly();
// Create a 'H264 Video RTP' sink from the RTP 'groupsock':
OutPacketBuffer::maxSize = 100000;
rtpVideoSink = H264VideoRTPSink::createNew(*uenv, &rtpGroupsockVideo, 96);
// Create (and start) a 'RTCP instance' for this RTP sink:
logDebug("Starting RTSP server ...");
const unsigned estimatedSessionBandwidth = 10000; // in kbps; for RTCP b/w share
const unsigned maxCNAMElen = 100;
unsigned char CNAME[maxCNAMElen + 1];
gethostname((char*) CNAME, maxCNAMElen);
CNAME[maxCNAMElen] = '\0'; // just in case
RTCPInstance* rtcpVideo = RTCPInstance::createNew(*uenv,
&rtcpGroupsockVideo, estimatedSessionBandwidth, CNAME, rtpVideoSink,
NULL, True);
RTSPServer *rtspServer = RTSPServer::createNew(*uenv, 8554);
if (rtspServer == NULL) {
logError("Failed to create RTSP Server");
exit(1);
}
ServerMediaSession *session = ServerMediaSession::createNew(*uenv,
"herosession", "video.sdp", "Session streamed by \"LiveCam\"",
True);
session->addSubsession(
PassiveServerMediaSubsession::createNew(*rtpVideoSink));
rtspServer->addServerMediaSession(session);
logDebug("RTSP server started ...");
logDebug("Beginning streaming ...");
char* url = rtspServer->rtspURL(session);
logDebug(url);
play();
uenv->taskScheduler().doEventLoop(); // does not return
}
你有什么建议吗？谢谢你的帮助！
