• My journey to Coviu

  27 octobre 2015, par silvia

  My new startup just released our MVP – this is the story of what got me here.

  I love creating new applications that let people do their work better or in a manner that wasn’t possible before.

  My first such passion was as a student intern when I built a system for a building and loan association’s monthly customer magazine. The group I worked with was managing their advertiser contacts through a set of paper cards and I wrote a dBase based system (yes, that long ago) that would manage their customer relationships. They loved it – until it got replaced by an SAP system that cost 100 times what I cost them, had really poor UX, and only gave them half the functionality. It was a corporate system with ongoing support, which made all the difference to them.

  The story repeated itself with a CRM for my Uncle’s construction company, and with a resume and quotation management system for Accenture right after Uni, both of which I left behind when I decided to go into research.

  Even as a PhD student, I never lost sight of challenges that people were facing and wanted to develop technology to overcome problems. The aim of my PhD thesis was to prepare for the oncoming onslaught of audio and video on the Internet (yes, this was 1994 !) by developing algorithms to automatically extract and locate information in such files, which would enable users to structure, index and search such content.

  Many of the use cases that we explored are now part of products or continue to be challenges : finding music that matches your preferences, identifying music or video pieces e.g. to count ads on the radio or to mark copyright infringement, or the automated creation of video summaries such as trailers.

  

  This continued when I joined the CSIRO in Australia – I was working on segmenting speech into words or talk spurts since that would simplify captioning & subtitling, and on MPEG-7 which was a (slightly over-engineered) standard to structure metadata about audio and video.

  In 2001 I had the idea of replicating the Web for videos : i.e. creating hyperlinked and searchable video-only experiences. We called it “Annodex” for annotated and indexed video and it needed full-screen hyperlinked video in browsers – man were we ahead of our time ! It was my first step into standards, got several IETF RFCs to my name, and started my involvement with open codecs through Xiph.

  Around the time that YouTube was founded in 2006, I founded Vquence – originally a video search company for the Web, but pivoted to a video metadata mining company. Vquence still exists and continues to sell its data to channel partners, but it lacks the user impact that has always driven my work.

  As the video element started being developed for HTML5, I had to get involved. I contributed many use cases to the W3C, became a co-editor of the HTML5 spec and focused on video captioning with WebVTT while contracting to Mozilla and later to Google. We made huge progress and today the technology exists to publish video on the Web with captions, making the Web more inclusive for everybody. I contributed code to YouTube and Google Chrome, but was keen to make a bigger impact again.

  The opportunity came when a couple of former CSIRO colleagues who now worked for NICTA approached me to get me interested in addressing new use cases for video conferencing in the context of WebRTC. We worked on a kiosk-style solution to service delivery for large service organisations, particularly targeting government. The emerging WebRTC standard posed many technical challenges that we addressed by building rtc.io , by contributing to the standards, and registering bugs on the browsers.

  Fast-forward through the development of a few further custom solutions for customers in health and education and we are starting to see patterns of need emerge. The core learning that we’ve come away with is that to get things done, you have to go beyond “talking heads” in a video call. It’s not just about seeing the other person, but much more about having a shared view of the things that need to be worked on and a shared way of interacting with them. Also, we learnt that the things that are being worked on are quite varied and may include multiple input cameras, digital documents, Web pages, applications, device data, controls, forms.

  So we set out to build a solution that would enable productive remote collaboration to take place. It would need to provide an excellent user experience, it would need to be simple to work with, provide for the standard use cases out of the box, yet be architected to be extensible for specialised data sharing needs that we knew some of our customers had. It would need to be usable directly on Coviu.com, but also able to integrate with specialised applications that some of our customers were already using, such as the applications that they spend most of their time in (CRMs, practice management systems, learning management systems, team chat systems). It would need to require our customers to sign up, yet their clients to join a call without sign-up.

  Collaboration is a big problem. People are continuing to get more comfortable with technology and are less and less inclined to travel distances just to get a service done. In a country as large as Australia, where 12% of the population lives in rural and remote areas, people may not even be able to travel distances, particularly to receive or provide recurring or specialised services, or to achieve work/life balance. To make the world a global village, we need to be able to work together better remotely.

  The need for collaboration is being recognised by specialised Web applications already, such as the LiveShare feature of Invision for Designers, Codassium for pair programming, or the recently announced Dropbox Paper. Few go all the way to video – WebRTC is still regarded as a complicated feature to support.

  

  With Coviu, we’d like to offer a collaboration feature to every Web app. We now have a Web app that provides a modern and beautifully designed collaboration interface. To enable other Web apps to integrate it, we are now developing an API. Integration may entail customisation of the data sharing part of Coviu – something Coviu has been designed for. How to replicate the data and keep it consistent when people collaborate remotely – that is where Coviu makes a difference.

  We have started our journey and have just launched free signup to the Coviu base product, which allows individuals to own their own “room” (i.e. a fixed URL) in which to collaborate with others. A huge shout out goes to everyone in the Coviu team – a pretty amazing group of people – who have turned the app from an idea to reality. You are all awesome !

  With Coviu you can share and annotate :

  • images (show your mum photos of your last holidays, or get feedback on an architecture diagram from a customer),
  • pdf files (give a presentation remotely, or walk a customer through a contract),
  • whiteboards (brainstorm with a colleague), and
  • share an application window (watch a YouTube video together, or work through your task list with your colleagues).

  All of these are regarded as “shared documents” in Coviu and thus have zooming and annotations features and are listed in a document tray for ease of navigation.

  This is just the beginning of how we want to make working together online more productive. Give it a go and let us know what you think.

• Find out what people are searching when coming from search engines

  7 novembre 2017, par InnoCraft — Plugins

  At InnoCraft, we know that SEO is an important topic for most of you. If you have not heard of this term before, SEO stands for Search Engine Optimization. It consists in having your content website visible within the search result pages without paying for ads. SEO is also often referred as “natural” or “organic” traffic.

  In SEO, one of the most valuable data to analyze is the keyword used by the visitor to come to your website. Since 2011, major search engines decided to not disclose this data anymore, that’s the reason why you are seeing the “Keyword not defined” data within some of your Piwik reports, also called “not provided” :

  

  Keyword not defined in Piwik

  The solution

  As your keyword data is collected by search engines, each of them provides the searched keywords within different services such as :

  • Google Search Console
  • Bing/Yahoo Webmaster tools
  • Yandex Webmaster

  Those services allow website owners to see how many times their website appeared within the SERP (Search Engine Results Page), how bots are crawling your pages, which search terms they used, and more. The drawback is, that they make take this data available only for a short period, you need to log in to all these services to get the insights you need and you cannot get aggregated overall keyword reports (over all search engines combined).

  The solution that gives you all this data in Piwik

  Would you like to know what the not defined search keywords in Piwik really are ? Would you like to combine keywords data from major search engines in one place ? Would you like to know how important your website is according to Google and Microsoft Bing and Yahoo ?

  At InnoCraft, the company behind Piwik, we created a plugin called “Search Engine Performance Keywords”. With this plugin, you will :

  1. be able to keep the search terms forever
  2. save time by crossing data from Google and Bing search within Piwik
  3. get an overview of how Google and Bing are crawling your site
  4. monitor search rankings and click-through rates for each keyword

  1 – Data ownership & data retention

  Once more, it is going back to Piwik roots. As Piwik is a Free software, you own the data you collect. Once the import is successful, you will be able to keep the keywords data as long as you wish. In the case of services such as Google Search Console, they will delete the data after 90 days !! Without our plugin you will not be able to analyze precisely how your SEO is doing month by month, year by year.

  2 – Save time by using a single interface

  Google and Bing have no interest in gathering data coming from various search engines… we do. As a result, with our plugin you can visualize the data coming from those two sources within a single report in order to analyze your SEO in a better way.
  You will not have to use spreadsheets anymore and no chance to miss some important keywords which you would maybe miss when you don’t aggregate them in a single report.

  

  3 – Crawl overview check

  Both Google and Bing have a crawl “budget”. This budget needs to be optimized in order for search engine bots to consider the most relevant pages. By gathering all the data within Piwik you will have a clear view of how well your website is appreciated by search engines :

  

  4 – Monitor search rankings

  The Search Engine Keywords Performance feature allows you to monitor search rankings for a given keyword and see his evolution :

  

  it also gives you the possibility to compare the performances of several keywords in order to see how your website is performing as a whole :

  

  How to get started ?

  The “Search Engine Keywords Performance” plugin has been developed by the InnoCraft team as a premium feature.

  Get Search Engine Keywords Performance on the Marketplace

  If you are not sure, note that InnoCraft is offering an unconditional and hassle-free 30-day money back guarantee period.

  Once you have installed the plugin, follow the guide in order to have it up and running.
  The installation process is not difficult in itself but takes some time as it requires to access to Google and Bing APIs.

• How to install ffmpeg

  I want to make a "mini" editor video. My goal is, cut some part of the video and then save it and also create an undo button. Now , I was looking for the best solution (This operation have to be done in a website) and I found that I have to use ffmpeg.

  that return me this :

  

  So, I have not ffmpeg installed on that server. The server should be Linux, I say this because I use one of the many website in Internet to discover it.
  

  I know that the website say that the Webserver is Engine-x, but my company has told that is Apache (as the php script already told me). Now , I found this link http://www.mysql-apache-php.com/ffmpeg-install.htm (in Stackoverflow and many other parts) that say how to install ffmpeg in Linux, but Where should I execute these commands ? Should I use Putty ? or What ?
