thibaultbee / srtdroid Goto Github PK

i want to use the lib send rtmp date, but the demo is not the send byte array api.

Hi, ThibaultBee, thanks for your good job.

I'm try to build this projiect on my PC, But I can't do it. Android studio reported a error when compiler the openssl project.

I don't know how to check the error message and fix it, could you help me?

how can I transfer the video stream from one android device to another and play it
just in lan

Like sending a file? Do all rendering and playback need to be implemented by myself?

the version is kotlin，is there a Java version available？

Hi，
i need your some help， How often to send a SDT PMT PAT？Whether to send PMT PAT when key frame？ what is the advantage of doing this？ Is there any document that can be queried？ thank you

Hello,

I'm trying to use your library with minSdk 19 to do that I've cloned the repo change the minSdk of the lib to 19. Everythings works great for API 21+ but it crashs on API 19 with the following stacktrace:

Do you have any idea how I could fix this ?

Hi， i used the project and streampack，it used the MsgCtrl when thranslate live streaming。
but i donot want use send method,i want to use srtSocket.getInputStream(null) and srtSocket.getOutputStream(null), I have a lot of confusion and need your help：

1. I used the live mode by rtmp over srt, whether the MsgCtrl parameter of getInputStream or getOutputStream can be passed empty？
2. I used the live mode by mpegts over srt, whether each package must accurately transmit the MsgCtrl package information ？

I'm new to SRT. Looks very promising protocol. I have a video delivery app on Android that captures video from camera, then uploads the video file to the server and another device can use it for playback later.

Will use of this protocol help with faster uploads/downloads? And do we have an example Android app and server for this purpose that I can use?

The root cause of this issue actually seems to be with the SRT v1.5.1 library itself, which is the version srtdroid currently uses. The issue appears to be fixed in the upcoming SRT v1.5.2, but I thought I'd flag this and share a workaround in case anyone else is having this issue now.

Summary: When not connected to the internet, calling connect(ip, addr) on a Socket and using a hostname for ip results in a SIGSEGV (SEGV_MAPERR), causing the app to suffer a fatal crash that cannot be caught.

Steps to reproduce:

1. Build and use the example srtdroid app (or a StreamPack example).
2. Disconnect from the internet (e.g. with airplane mode)
3. Set the IP to a hostname that needs name resolution (e.g. "stream.example.com")
4. Attempt to start streaming as a client.

Expected Result: A catchable exception indicating a problem with resolving the hostname and connecting.

Actual Result: A segfault that causes the app to crash.

Analysis:

Socket.connect(ip, addr) is an alias for Socket.connect(InetSocketAddress(ip, addr)). InetSocketAddress provides name resolution if ip is a hostname and not an IP address. However, if name resolution fails, its getAddress() method returns null. Since InetSocketAddress::getNative(...) returns nullptr when getAddress() is null (InetSocketAddress.h:55), the sockaddr pointer passed into srt_connect(...) at glue.cpp:300 is a null pointer.

In the SRT library, srt_connect wraps CUDT::connect which calls CUDTUnited::connect. In v1.5.1, there is no null check for the sockaddr*, and it gets dereferenced when constructing sockaddr_any in the method at netinet_any.h:148, resulting in the segfault. In v1.5.2, they've added a null check at api.cpp:1244 which appears to fix the issue.

Workarounds:

A. Compile srtdroid by changing the SRT version to 1.5.2-rc2 or similar in CMakeLists.txt. This seems to fix the crash in the srtdroid example app (showing a connection error popup instead). I haven't tested if any features are affected by the new version though.

B. Do val foo = InetSocketAddress(ip, port) yourself, check if foo.address is null, and call Socket.connect(foo) directly with this safe InetSocketAddress so no null pointer is passed into the underlying library. This is the solution I've used in the extension to StreamPack I'm working on so I didn't have to recompile srtdroid.

Hello,

I have tried your SRTWrapper for android seems to work except for streamID. I set it before making socket connection, but the reciever/listener does not get it... Any help would be appreciated.

I am trying to send my device camera stream to a srt server I have on my laptop. The code I am using is the following:

Srt srt = new Srt();
srt.startUp();

// create SRT socket to send stream
Socket clientSocket = new Socket();
clientSocket.setSockFlag(SockOpt.TRANSTYPE, Transtype.LIVE);
// connect socket to srt server (vMix running on my laptop)
clientSocket.connect("192.168.43.50", 11001);

// create udp listening on 0.0.0.0:7800
new Thread(new Runnable() {
	@Override
	public void run() {
		byte[] data;
		try{
			byte[] buffer = new byte[1316];
			DatagramSocket socketUDP = new DatagramSocket(7800);
			while(true){
				DatagramPacket udpPacket = new DatagramPacket(buffer, buffer.length);
				socketUDP.receive(udpPacket);
				data = udpPacket.getData();
				// send received data to srt server
				clientSocket.send(data);
			}
		}catch (Exception ex){}
	}
}).start();

// I use ffmpeg to capture android camera, and stream it to socketUDP
int rc = FFmpeg.execute("-f android_camera -video_size 320x240 -input_queue_size 60 -i 0:0 -r 30 -f h264 udp://0.0.0.0:7800");

As you can see, the code is pretty simple. I do not know why it doesn't work. I think that the problem is on the srt socket settings.

If I send the android camera directly by udp to my laptop, and use ffplay on my laptop to see it, it works fine. So I think the ffmpeg command is ok.

Another interesting thing is that if I stream my android camera using the app Larix Broadcaster, it works fine (I can see the camera on my laptop using vMix)

Last but not less important, when I run the code above, It doesn't crash, and despite I can't see the camera on vMix, if I open on vMix the statistics dialog, I can see that the vMix is receiving data from my device.

Socket socket = new Socket();
socket.setSockFlag(SockOpt.TRANSTYPE, Transtype.LIVE);
socket.setSockFlag(SockOpt.PAYLOADSIZE, 1316);
socket.rendezVous("0.0.0.0", remotehost, 5000);

if I set remotehost a non existent ip, connection is not established
Caller and Listener modes work fine.
I use android apps Larix Player, Haivision Play, Haivision Play Pro
Thank you.

Hi，My program already has rtmp, I want to add srt to this project，Whether this library can meet the needs, or need to use StreamPack？ thank you
