VoIP videoconference IOS App, Open WebRTC

In this post I will show my work on WebRTC, an open project that provides browsers, embedded and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. With OpenWebRTC you can build native WebRTC apps that communicate with browsers that supports the WebRTC standard, such as Chrome, Firefox and Bowser. OpenWebRTC is especially focused on mobile platforms, with powerful features such as hardware accelerated video coding and OpenGL-based video rendering. Sounds fancy right? Yes, it does. But why choosing WebRTC to do VoIP over, lets say, other existent signalling (like SIP or skype) and encoding technologies (just like H264, H323, V8, etc...)? For me, the answer was simply: Copyright issues. So, I wanted to develop an IOS app for my Iphone 6, brand new IOS 9 (not the preview version already), and that meant that I could not use code covered by the GPL licensing.

That is right. GPL licensing allows you to freely use and redistribute the code, but it does not allow you to pose further restrictions while doing so. Sadly, Apple App store does, REGARDLESS of it being paid or free. WebRTC is distributed with a BSD licensing, meaning that you can do whatever you like with it, for as long as you put the due disclaimer in your code. So, currently you can choose one out of two possible implementations for WebRTC: WebRTC from Google, and OpenWebRTC from Ericsson (Germany). Both do almost the same, but I prefer the OpenWebRTC due to the fact that I want to develop for mobile. Quick comparison can be found at (https://bloggeek.me/ericssons-openwebrtc-project/):

Therefore, I am using OpenWebRTC as a choice. I followed the official tutorials to build a native IOS application (you can build a hybrid one, meaning the use of a brower view inside an app), and there are other tutorials for other platforms just like Android:

https://github.com/EricssonResearch/openwebrtc-examples/wiki/Developing-iOS-apps

https://github.com/EricssonResearch/openwebrtc-examples/wiki/Developing-a-native-iOS-app

The app I developed is based on the Original Native app from the OpenWebRTC available here (https://github.com/EricssonResearch/openwebrtc-examples/tree/master/ios/NativeDemo). What I did in this application was creating a XCode project with all the dependencies solved (you do not need CocoaPods to run it), and I solved most of the problems to run in in IOS 9 (it does compile for previous versions like IOS 8, with extra warnings naturally).

So, The Portrait view that is buggy from the NativeDemo app from OpenWebRTC is:

Portrait, after fixing the error, as well as Landscape:

As you can see, in Portrait is not perfect, but the video is stretched to meet the box. As the pull I did through CocoaPods grabbed the compiled binaries from OpenWebRTC and OpenWebRTC-SDK, I could not edit the video feed itself. For that, I would have to build the application from scratch and build the OpenWebRTC source files (wasting almost 10 hours of my life! Trust me, I did it). So the solution I found was manipulating the view itself, through rotations and translations and scaling. Though, in Landscape mode, it works better.

The application was tested by the following demo: http://demo.openwebrtc.org:38080

Then, you have to select the same id in the application and in the demo in the browser.

At the server side, once the connection is established in the same room, you can see as follows:

(Portait)

and in Landscape as well. You can see the server updated the orientation of the video properly:

WeOnTV mobile já disponível

almeida — Wed, 12 May 2010 16:40:46 GMT

Tal como prometido, estivemos a ultimar a aplicação mobile para ser utilizada em paralelo com o WeOnTV.

Este SID ("Secondary Input Device") permite utilzar um telemóvel iPhone, Android ou Symbian como teclado para o envio de mensagens para conversas que estejam activas no WeOnTV. Podendo aproveitar os teclados virtuais, físicos, a velocidade de processamento do telemóvel e o T9, a experiência de enviar mensagens melhora significativamente. Mas queremos o vosso feedback!

Como posso utilizar?

Muito simples. Bastam 3 simples passos:

Ligar (caso ainda não esteja) o WeOnTV na box e iniciar pelo menos uma conversa;

Ligar o telemóvel à rede Wi-Fi do Meo em casa;

Aceder no browser do telemóvel a: http://a.md/weon

A aplicação apresenta automaticamente a lista de membros da casa com sessões activas. De seguida basta seleccionar o membro e enviar mensagens.

Como se poderá ver na televisão as mensagens enviadas aparecem na tab da respectiva conversa.

Atenção que o WeOnTV mobile apenas funciona se o telemóvel estiver ligado à rede Wi-Fi do meo lá de casa e o WeOnTV estiver iniciado na TV. Os alertas aparecem para nos avisar.

Boas mensagens!

Os serviços web das bibliotecas e os dispositivos móveis... mobile libraries

pedroprincipe — Wed, 03 Jun 2009 00:34:00 GMT

Devo confessar que tenho andado a tentar acompanhar umas coisas sobre "mobile"! Procurando estar atento aos serviços que as bibliotecas prestam a utilizadores com dispositivos móveis, e concretamente tentando perceber de que modo é que as bibliotecas estão a preocupar-se em assegurar que os seus recursos web, nomeadamente os seus portais e catálogos, fiquem devidamente acessíveis nestes dispositivos.
Partilho este interesse como justificação da vontade em destacar este vídeo promocional que tive agora conhecimento via Tame The Web.

Para os mais interessados, digo que vale a pena seguir o blog Mobile Libraries em http://mobile-libraries.blogspot.com.
Nota final: Depois de escrever este post lembrei-me que há uns meses tinha lido algo sobre a utilização de pda's nas bibliotecas da área da saúde. Fui recuperar essa dica e cá está: foi uma apresentação nas Jornadas da APDIS do ano passado - "Implementação de serviços de referência para pda's nas bibliotecas de saúde".
