Hi guys,
I not sure this problem is relative with your source code or not. If you have time, please help me. I'm using for wrapper file to build an opus codec lib. For more detail in here.
http://stackoverflow.com/questions/27355052/java-lang-unsatisfiedlinkerror-when-using-with-android-5-0

Overall: with your wrapper and source code from opus-codec.org, it work perfect on android 4.0+ but in Android 5.0 it can't find any native method and this is the exception: java.lang.UnsatisfiedLinkError: No implementation found for ... let me know if you have solution or reply in stackoverflow.

Best regards,

If I use libjitsi.jar copied from videobridge(https://download.jitsi.org/jitsi-videobridge/linux/jitsi-videobridge-linux-x64-202.zip), everything is OK, no exception appears.
But if I use libjitsi.jar built from latest version of libjitsi repo, there will be some DTLS exceptions:
BTW, libjitsi and bouncycastle(bcpkix-jdk15on-151.jar, bcprov-jdk15on-151.jar) have been updated to latest version.

Here are DTLS exceptions:

Dear team,

my win 7 64 bit installed jitsi and it can find my web camera and video preview is OK. installing folder: D:\javaApp\SIP\Jitsi

and I clone libjitsi to import it to eclipse. and I wrote one class to detect web camera as following:

package org.jitsi.demo.video;
import java.util.List;
import javax.media.CaptureDeviceInfo;
import org.jitsi.impl.neomedia.MediaServiceImpl;
import org.jitsi.impl.neomedia.device.DeviceConfiguration;
import org.jitsi.impl.neomedia.jmfext.media.protocol.directshow.DSCaptureDevice;
import org.jitsi.impl.neomedia.jmfext.media.protocol.directshow.DSManager;
import org.jitsi.service.libjitsi.LibJitsi;
import org.jitsi.service.neomedia.MediaType;
import org.jitsi.service.neomedia.MediaUseCase;
import org.jitsi.service.neomedia.device.MediaDevice;

public class MediaTest {
public static void main(String[] args){
LibJitsi.start();
MediaServiceImpl mediaService
= (MediaServiceImpl) LibJitsi.getMediaService();
DeviceConfiguration deviceConfiguration = mediaService.getDeviceConfiguration();
List<? extends CaptureDeviceInfo> infos = deviceConfiguration.getAvailableVideoCaptureDevices(
MediaUseCase.CALL);
System.out.println("infos="+infos);
List devices = mediaService.getDevices(MediaType.VIDEO,
MediaUseCase.CALL);
// DSManager ds = new DSManager();
// DSCaptureDevice[] devs = ds.getCaptureDevices();
// System.out.println("devs="+devs);
}

}

and I set -Djava.library.path=D:\javaApp\SIP\Jitsi\native in eclipse "Run Configuration--->Arguments--->VM arguments.
but got the following error:

do I missing something or configuration is error?

would you please tell me how to detect camera with libjitsi?

thx a lot

Those threads hang at places:

Project 'libjitsi' is missing required library: 'lib/jspeex.jar' ?

SctpNativeWrapperTest fails on Win7-64 bit with the following:

It looks like replacing jnsctp.dll from a build prior to the maven changes fixes the issue.

Attached is a DependencyWalker image from the jnsctp.dll with this issue

When we have video enabled locally and put the other end on hold, we should transmit a static image or blackness instead of the stream captured from the camera.

Boris Grozev has reported a crash in Jitsi Videobridge which appears to be caused by the OpenSSL HMAC-SHA1 JNI implementation: http://pastebin.com/Em2SrZkU

Curious to see an open source Java library for this. Would you care to clarify the license? Thanks!

I checked the source code of jitsi and found that the error may be generated from this
libjitsi/PushSourceStreamImpl.java at master · jitsi/libjitsi · GitHub
and the MaxPacketsPerMillisPolicy.PACKET_QUEUE_CAPACITY is read from configuration file.
However, I couldn't find the configuration file for it.

Any one know where is it defined?

It fails to find vpx_codec_mmap_t and vpx_codec_{get,set}_mem_map. They were probably (re)moved at some point in libvpx. We should update our code accordingly.

Hello everyone
Can provide more examples to use libjitsi?
For example, record a video, take pictures, transcoding, etc.
AVReceive2 and AVTransmit2 difficult to understand for newcomers

Hi,
I have implemented a java application, that read RTP packet saved with wireshark (pcap file).
I'm able to read the RTP with VP8 codec (payload type = 120).
How I can save a webm file from them?
Please can you help me?

Thanks in advance
Francesco

I am currently evaluating Libjitsi.

The problem I have so far is that the equipment accepts only RTP packets containing '40ms' of PCMU audio.
It seems that Libjitsi is scheduled at '20ms'. Am I right?
If so, how can I adapt to that requirement?

i am try to recompile fmj.jar for android, i found fmj source in github, but the version is not correct. i need the fmj source for android(r36), the author is lyubomir.

please help, thank you very much.

On lines 170 and 220, the output buffer has its timestamp set to Buffer.TIME_UNKNOWN or -1 instead of simply copying the input buffer timestamp or using the PTS or DTS from the native decoder.

https://github.com/jitsi/libjitsi/blob/master/src/org/jitsi/impl/neomedia/codec/video/vp8/VPXDecoder.java

Setting this value to unknown causes issues for implementers wanting to re-encode or use the frames in follow up processing.

The opponent hears the voice stutter/lagging by using any bluetooth headset under Mac OSX. Normal USB-Headsets are working fine. The Bluetooth Headsets working fine with other SIP-Software like Zoiper/Telephone. Tested from two persons under Asterisk with Codec G722.

I discussed this on the Jitsi mailing lists and the link to that discussion is: http://lists.jitsi.org/pipermail/users/2014-July/007447.html

In the view of creating my custom AudioMediaStream which inherits from AudioMediaStreamImpl,
I need a way to modify the 'transformEngineChain'.
Unfortunatelly, this is a private field and no get method exist!
I suggest to create a public getTransformEngineChain method!

the function

  org.jitsi.impl.neomedia.transform.TransformEngineChain 
  public boolean addEngine(TransformEngine engine)

is faulty. It does not do anything.
Should be modified

I would like to have audio input (coming from RTP stream) simultaneously on loudspeaker and headset.
Is that possible?

Make sure we statically link libvpx into binary libjnvpx, as the lib is not detected when building binary debian package and breaks the process.

I have to drive equipments controlled via ABCD signalling (see http://www.rfc-base.org/txt/rfc-5244.txt)

Libjitsi sounds very promising and I have already modified the source to cope with this and it works.

Is the community interested in this new capability?
If so, I would need some guidance to make sure I am following the 'philosophy' of the library.

Damian Minkov and Ingo Bauersachs reported the attempting to record calls in Jitsi on certain old versions of OS X and recent version of Windows crashes the process.

I'm using libjitsi's Opus class in a project. It works perfectly with version 212, before the outputOffset was added to Opus.encode() and Opus.decode(). I've tried the later version 266 and changed my code to include an outputOffset (which I've simply set to zero) but I'm getting problems, Opus.decode() is returning -1.

Two questions:
-Are there any tests for this class to be sure Opus is working and its not just me making a mistake?
-Are there any plans to for the Opus class to provide more information about problems during encode/decode? A general -1 error code without no console output is very unhelpful.

Make sure we statically link usrsctp into binary libjnsctp, as the lib is not detected when building binary debian package and breaks the process.

I want to compile and build libjitsi for com.example on Android . But when I include the renamed jar, it has errors.
I renamed from org.jitsi to com.example using Ideal J but it shows errors

What is the best to use libjitsi for a custom application?

In the RED filter transform engine, if, instead of left-shifting the payload, we right-shift the header, the SRTP auth tag becomes corrupted and the client discards the packets because of that.

This is an indication that we have a non-zero offset bug somewhere in libjitsi, probably inside the SRTP transformers.

I have seen audiosystem for Portaudio, Pulseaudio...
Is there anything for Jack?

First G722 rtp packet has timestamp 2^32-1.

I found the fix in jitsi repo for bug #872 (see below), and saw that "outputFormat =" is missing for G722 in (src/org/jitsi/impl/neomedia/codec/audio/g722/JNIEncoderImpl.java:118). I can not build and verify this. So maybe someone is able to try this.

regards,
chris.

Is there a java method in this project to mix two audio files?
Thanks.

When i use the grabScreen method it fills my byte array with -1

What am i doing wrong?

                    Rectangle rect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
                    int width = rect.width;
                    int height = rect.height;
                    int size = width * height * 4;
                    while (true)
                    {
                        byte[] bytes = new byte[size];
                        boolean success = ScreenCapture.grabScreen(displayIndex, 0, 0, width, height, bytes);
                        // do something with the byte array
                    }

What would cause this to be null after a successful start?

Here are the steps leading up to the method call:

• get MediaService instance
• get MediaFormatFactory via MediaService instance
• get Audio and Video device instances
• create MediaFormat for audio and video using MediaFormatFactory
• create SrtpControl via MediaService
• create MediaStream for audio and video using MediaService with Device
  and SrtpControl parameters
• add dynamic payload type to MediaStream instances
• set direction to SENDONLY on MediaStream instances
• set format on MediaStream instances
• create a DatagramSocket for both rtp and rtcp
• create InetSocketAddress for both ports on my public IP
• create a StreamConnector for both audio and video
• set StreamConnector on each MediaStream instance using DatagramSocket
  instances
• create a single MediaStreamTarget using the InetSocketAddress
• set MediaStreamTarget on both MediaStream instances
• set names on MediaStream instances ("audio" / "video")
• start SrtpControl with MediaType.AUDIO
• start the audio MediaStream instance
• start the video MediaStream instance

All of these actions complete without an exception and the following is
output into my log:

After all this completes, I call
InetSocketAddress audioAddr = audioMediaStream.getRemoteDataAddress();
and it always returns null; same for my video MediaStream.

If a sample class is required, I can create one.

I've tried to stream audio to a SIP Account with the opus codec. Setting: 128 Kpbs.
I've started the connection and it works, but the upstream was only at 40 Kbps and not at 128 Kbps like configured.

The latest version wont build in Maven.

As for Rolf Hamburg, I have the same issue on Ubuntu 14.04 LTS

Hi,

We are using libjitsi (569) to develop a java8-scala-application with a VoIP-component for Linux (pulseaudio).
Our problem is the correct selection of the audio-device.

At startup we show a selection-window of the active devices (capDevicesList), which we get from:
deviceConfiguration = mediaService.getDeviceConfiguration()
capDevicesList = deviceConfiguration.getAudioSystem.getDevices(AudioSystem.DataFlow.CAPTURE)

The user selects a device (selectedDevice) from capDevicesList, which we set into the AudioSystem:
deviceConfiguration.getAudioSystem.setDevice(AudioSystem.DataFlow.CAPTURE, selectedDevice, true)

The MediaDevice is build like this:
mediaDevice = new AudioMediaDeviceImpl(selectedDevice)

Then we create a MediaStream:
mediaStream = mediaService.createMediaStream(mediaDevice)

If mediaDevice is the only device connected to the computer, everything works fine. But if there's
another device connected, the mediastream doesn't use necessarily mediaDevice. The above procedure of
selecting the device doesn't has any influence on which device will be used.
What we are doing wrong?

Thanks,
Rolf

When I tried to make a video call with only H263-1998 enabled, Jitsi crashes the Java VM. Crashdump at https://gist.github.com/jitsi-jenkins/19d305e39bf9e04c2d10

I am looking for FMJ.jar source code.
Where does this one come from?

Hello,

the screen capturing feature currently does not capture the mouse cursor. At least in the X11 part, XGetImage gets the image without the cursor. A cursor could be got with Xfixes XFixesGetCursorImage and overlaid on the resulting image. I don't know how could it be accomplished in other systems.

JVM crashes with Ubuntu 14.04 webcam streaming in both Jitsi and Libjitsi, Java 7 and Java 8. The following error logs print from the console:

...
# Problematic frame:
# C  [libjnffmpeg.so+0x1129b6]  ff_mjpeg_decode_sos+0x19b6
...

Note that I am getting this EXACT SAME "A fatal error has been detected
by the Java Runtime Environment:" when I try to use Jitsi
(jitsi_2.8.5426-1_amd64.deb) from my laptop. I made a post about this Jitsi
Java error as a bug report to the devs mailing list. When I try to run
Jitsi from the terminal, I get the following printout from the terminal:

johnmichaelreed2 at JohnReedsGalago:~$ jitsi
...
# Problematic frame:
# C  [libjnffmpeg.so+0x1129b6]  ff_mjpeg_decode_sos+0x19b6
#
...

All I did was typed in "jitsi" and then went to the top bar and clicked:
Tools > Options > Video (I can see myself in the Devices webcam tab -
webcam recording light is on) > Encoding [crash]

As soon as I click on "Video > Encoding", "Video > More settings", or
"Security", Jitsi crashes in a manner similar to the way AVTransmit2
crashes on my computer.

I assumed the Maven build was ready for prime-time, however I see this error when I attempt to build master.

Hello There, I just started doing research on Jitsi- VideoBridge and I am developing a desktop sharing application( Live streaming Audio & Video) which can run on all the platforms natively using WebRTC. Jitsi is all written in JAVA and can someone share/guide me C# implementation of Jitsi. I would also like to know what Frames/sec does jitsi offer for 1080p resolution. Let me know any other info is required.
