Tokbox video chat give connection timeout error - html5-video

It working on same OS machine. If i am publisher with used of mac machine and subscriber side am using ubuntu os then give server connection timeout error.

If OpenTok is working on the same machine but not across multiple machines, the issue is most likely caused by your network. You can check if your network supports webrtc using this tool: https://chrome.google.com/webstore/detail/opentok-diagnostic/elanokbchpinmganpfaigciognfpcfei
If you are using flash, you have to enable rmtp ports. Check your network by going to the flash diagnostic tool here: http://tokbox.com/user-diagnostic/

HoloLens device portal not available

When connecting HoloLens via USB to my computer, the device portal is still not available after setting it up as explained in the install tools page.
All I get in the browser 127.0.0.1:10080 is the generic "unable to connect" page.
Is there any way to know what is failing? What could I check? Any tip will be appreciated!
EDIT: browsers used: Edge, Firefox and Chrome.
EDIT2: Hololens development mode is on.
Connecting over USB requires the PC be running IPoverUSB, which is installed with the Windows 10 SDK. You can verify that it's running by checking the Services tab of Task Manager for IpOverUsbSvc.
FYI, another resolution to this issue may be the USB port you are using.
I initially was using a USB 3 port (which I've used to flash my HoloLens many times) and had the same issues.
On a whim, I switched to an older USB2 port and it's working perfectly now. SO try different USB ports if you are having this issue.

Remote connection to embedded device in field

I would like to ask about the way how to establish remote connection to Linux based embedded device in the field.
I have a small linux board I want to place in remote location. It has an internet access through ethernet. Than I have a Linux server with public IP to be able to tunnel connection.
And finally, I want to connect from my PC to this device.
I don't feel yet competent enough to code my own tcp sockets etc. to reroute the connection :) So what would be the easiest way to do that only with available linux tools? And BusyBox toolset on endpoints.
Thank's a lot!
I think that using OpenVPN would be a easy way to tunnel to the device. You can cross compile it and set it up as a client on the embedded device. Then you install it on your Linux box and set it up as a server.
Finally you install it on your work PC and set up as a client there.
It gives you a virtual network where all clients can talk to each other like they would be on a local network.

How do I access a GPS from Windows IoT on Rasperry Pi?

I have done this when running Debian using gpsd. But when running Windows IoT preview...what is a way to get the NMEA sentences off an attached GPS (on the USB port). Is that kind of support around yet?
Currently this support is not yet available but it is being actively developed. Furthermore the Geolocator API is broken. Unfortunately I don't have an ETA for this but its coming.

Calling selfhosted WCF service from Windows Phone 8 Emulator

My selfhosted WCF wervice works fine with any browser on the domain, and also with a WinForm client. In a Windows Phone 8 app I can create Service References OK. Trying to consume the service from within the app running in the emulator it causes the System.Net.WebException: The remote server returned an error: NotFound.
What I have done:
allowed URL registration
firewall inbound rule for the specified port
enabled WCF Services, HTTP Activation (Windows Features)
In the Hyper-V settings for the Emulator it lists 4 network adapters: Windows Phone Emulator Internal Switch, Intel...Gigabit Network Connection Virtual Switch and 2 VMware related switches.
Can the presence of VMware cause this problem? (I have stopped the (4) VMware related services.)
What else can I check or do?
After a full day of working on the issue (not knowing anything about Hyper-V didn't help) I (we) worked out the problem:
In this particular, but quite common setup, both Ethernet and Wireless Network Adapters were enabled, and Ethernet ranked above Wireless, as you do to give the cable connection precedence over wireless when both are available.
Even though the Ethernet cable was disconnected at the time the Emulator was started/created, Hyper-V created Ethernet as the only external Network adapter to use. But the because there was no cable, the adapter was physically disabled and the local WCF service (which was running on the wireless network) could not be found.
Disabling the Ethernet (hardware) adapter (Control Panel), then deleting the emulator, and reconstructing it by launching a phone app in VS fixed the connection issue. On inspection the Wireless adapter is then assigned as the external adapter ("Virtual Switch") to use.
Hope that helps someone.

How to use USB over Remote Connection to a Virtual Machine

I'm trying to do mobile application development (BlackBerry, Android) on a virtual machine. My idea is that no matter what desktop I'm on I can open a remote connection to the virtual machine and have my mobile development environment ready. The problem is that I would like to deploy code to the mobile device as if it were physically connected to the virtual machine. Ideally the devices will be plugged in to the client machine that is creating the remote connection.
I'm currently using VMWare workstation to manage my virtual machines, I've done a bit of research to see what the best solution for connecting my usb devices over the network is.
There are a multitude of pricey USB over network solutions that may or may not work for what I'm trying, but I would like to avoid those. I would be interested in a free open source solution where both the usb host and usb client are windows machines. This is close to what I am looking for http://usbip.sourceforge.net/, but you can't host a device from Windows.
It appears that I may be able to do this with a Hyper-V VM and RemoteFX through Microsoft RDC, but I would like this to work on my existing VMWare VM.
The quickest solution I've found is a network usb hub that would allow me to connect the devices over the network, but this would force me to be attached to the hub which is a problem if more people come on my project.
Ideally I'm looking for an existing software solution to my problem. Any suggestions?
Also can anyone confirm this would work in Hyper-V using RemoteFX?
I would consider porting your VM over to VirtualBox from Sun (now Oracle) they have remote USB support out-of-the-box, and are very stable.
I've ported machines the other way (for work) and it's not difficult.
