We have integrated the single video conferencing with quickblox in iOS and are working perfectly.Now we need to implement multiple video conferencing facility in iOS.For that I tried to create two instances of
[[QBChat instance] callUser:user.ID conferenceType:QBVideoChatConferenceTypeAudioAndVideo];
and set different UIImageviews in the
- (UIImageView *) viewToRenderOpponentVideoStream datasource method based on the instances.I tried to establish multiple communication between the users using 3 devices.But the server allows only 2 devices to communicate each other.Is there any way to allow the third device to establish communications between the third device and other 2 devices?

Hi I have currently web app where users can stream video from camera to each other, but I have question:
Is it possible to stream from 2 cameras same time from one user and send this two streams to another one ?
I'm using javascript with peer.js,node.js,socke.io and express.
Can we control multiple DSC-QX100 cameras using the Camera Remote API SDK from an iPad OS7?
The objective is to cause multiple cameras to "snap" picture at the exact same time. Perhaps each camera has an address (serial number)...can the software communicate with all cameras at the same time using multiple addresses? Need is limited to still photos and so-called fast, rapid photography. Video not necessary.
If so, how?
Unfortunately you can only control one QX100 lens at a time. This is because the lens connects over WiFi and you are limited to only a single WiFi connection at once on an iPad. It may be possible using a desktop PC with multiple wireless cards installed but that would be the only way.
As the Sony rep said, there's no way to do this with "officially supported" techniques.
The reason for this is that the camera acts as a WiFi Access Point (AP) - so while multiple devices can connect to it, most mobile devices can only connect to it and not anything else (since iOS and Android don't support connection to multiple APs simultaneously). This is also why you can't use other network interfaces when connected to the camera. (I don't know about iOS, but Android always prioritizes WiFi over cell network data, for example.)
Android devices have a feature called "WiFi Direct" that provides more flexibility in terms of peer-to-peer interconnection, but iOS does not support WFD. The QX100 DOES respond to WFD invites, and you can accept a pairing request with (if I remember correctly) a long-press of the shutter button. However, the official app only supports normal WiFi AP connections.
I have not yet attempted to see if using Sony's remote API in combination with the (unsupported but apparently present) WiFi Direct capability works.
More info on Wifi Direct and Android can be found at http://developer.android.com/guide/topics/connectivity/wifip2p.html
Marlin SONY, I disagree, wifi is Ethernet and by definition can handle multiple devices on the same network. If you run a phone or iPad as a hotspot and connect multiple devices, it works.
Multicam Switcher Basic is an example of a free app that supports cutting together multiple camera angles live. Unfortunately the app is still being developed so features like third party camera support isn't included, but it does show what is possible and awaits development.
I think this should be possible. Apps like CollabraCam™ (Multicam Social Video Production) or RecoLive MultiCam prove that is possible to use mulitple cams simultaneous.
I need someone too to develop an App to be able to use "two" sony dsc-qx for 3D shoots. Please, if You know how or who can do this contact me email#3-d.re
Is there a way how to get list of all devices connected to the Bluetooth peripheral?
I want to connect to iBeacon and check if another iPhone is connected to it.
No, two reasons why not:
iBeacons are not connected to the iOS device, iBeacons are broadcast only and no back communication exist from the phone to the beacon.
Knowing details of other BT 4.0 Centrals connected to a Peripheral are not in line with the the privacy features of Bluetooth 4.0. iOS and other Centrals are are using resolvable private addresses, in order to avoid situation like you are describing.
#barbazoo is correct that you cannot do exactly what you are asking because iBeacons only transmit data -- they have no idea what devices see them.
You can accomplish something similar, however, if you have an app running on each of the iOS devices you mention, and you have a server where you can build a web service. The web service would expose two methods:
reportIBeaconVisible(iBeaconProximityUUID, iBeaconMajor, iBeaconMinor, myPhoneAdvertisingId)
queryVisiblePhones(iBeaconProximityUUID, iBeaconMajor, iBeaconMinor)
The app would report each iBeacon it sees using the first method, passing the iBeacon's identifiers, along with the phone's advertising identifier to the server.
The app could then use the second method to ask the server what other phones have seen the exact same iBeacon, which would return a list of phone advertising identifiers.
You'd have to have logic on the phone to only report data to the server at a reasonable frequency. You'd also need code on the server to automatically delete phone records in the list if the phones haven't reported seeing a beacon in a certain time interval.
I want to develop an App that requires wired communication between Web cam type video camera and iPad2. Basically I will directly connect Web cam and iPad2 using cable and when I start web cam, whatever images(picture/video) captured by web cam should be displayed on iPad2.
Based on my research on this I found that iPad2 cable is only made for iPod Program so the connector is not a traditional USB port I can't do direct communication between web cam and iPad2. Am I missing anything?
We are going to use Vivotek camera and they have mentioned here that we can use safari to receive the Motion-JPEG stream. I am wondering if that could also possible on iPad 2 and is it reliable?
Further I found Apple's MFi Program to develop electronic accessories that connect to iPod, iPhone, and iPad. Is there anyone out here used this already and know more about this if I can go for this?
Thanks.
You can receive a motion jpeg stream in mobile Safari or in a UIWebView in a custom app. I am not able to (yet) successfully receive a motion jpeg stream via an AVPlayer, AVPlayerItem or AVURLAsset.
Becoming a MFI authorized company is non-trivial (I tried once). They want larger established companies that have demonstrated they have the skills and manufacturing know-how/contacts to produce quality accessories.
Curious if you can step back from your initial requirement and see if you can figure out how to do it wirelessly for at least the last step to the iPad 2. Can go wired up to 2 feet away from the iPad and use a local private wifi network for that last 2 feet (say).
I recommend you add (use existing, or purchase) a wireless gateway. Connect the camera to the gateway, and then connect the iPAD to the wireless network, and then browse in safari to the camera and then you can view the image. There is no "hard wired" way to get this to work.
As for the "hard wired" portion of the question, I do not believe that is not possible without a lot of work and hardware. There is no "video in" on an ipad to make it a monitor for a camera.
I just want to know that is it possible to communicate two different apps in different device. Like I have a sample app in device A App name A and in another device B i have a app B I want to share some things between them. I came across to GameKit framework in iOS but I made a app when it is installed in both device they communicate succesfully but what if apps are different and what is the size limit of the data to send it over bluetooth in iOS.
Any idea how to implement this feature?
Two different apps can communicate via Bluetooth using GameKit as long as they both agree on the protocol (i.e. if you wrote both apps, or you know what protocol the other app is using).
There's no limit to the amount of data they can exchange, although there is obviously an upper limit on bandwidth (bytes per second).
Does that help?
