• Understand your visitors by seeing where they click, hover, type and scroll, and replay their actions in a video

  18 mai 2017, par InnoCraft — Plugins

  Hi, this is Mike from InnoCraft, the company of the makers of Piwik Analytics which is used by over 1 million websites and apps in over 150 countries.

  I’m very proud to introduce you to our Heatmap & Session Recording feature which lets you analyze your visitors’ behaviour on a whole new level that was not possible before.

  With Heatmaps you can see where people think something is clickable but it is not, how far down the page do they scroll, whether they see your important buttons and Call To Actions, or even whether you can re-position your page layout to put the important content in more visible places. Both the mouse movements and all clicks are recorded and viewable on these new beautiful heatmap visualisations.

  With Session Recordings, you get to see a video showing exactly what a visitor did on your pages, including all mouse movements, scrolls, text typed in the keyboard, and more. Using these recordings you can improve the usability on your website, replace costly (and less effective) eye tracking sessions, and you can now see exactly what problems your visitors experience or how they behave on your website. This gives new insights and ability to understand what your users think.

  -> Read the rest of the story on the Heatmaps & Session Recordings Marketplace page.

  What does the new Heatmaps reports look like ?

  Here is below just a little preview of the new Heatmaps reports.

• How to link libav* libraries of FFmpeg in my own program ?

  20 août 2019, par zuguorui

  I am new to FFmpeg, now I want to use the FFmpeg codec compenet in my own program. I’ve followed the guide on FFmpeg wiki to complie the libraries the FFmpeg and get them done. But when I compile my own program it always tips ld: library not found for -lavutil or something like this.

  Environment：MacOS 10.14.6

  Compile tool : clang++

  steps :

  (1)Install all needed libraries follow the wiki.

  (2)./configuure --prefix=host --enable-shared --disable-static

  (3)make

  (4)make install, after this step, I got compiled files in dictionary host.

  (5)copy the source code in FFmpeg/doc/examples/decode_audio.c to create a new project, and copy includes and dylib files to my project dictionary. The structure of my project is :

  ./
  
  |----FFmpeg
  
       |----include
  
            |----libavcodec
  
                 |----*headers*
  
            |----libavformat
  
                 |----*headers*
  
            |----libavutil
  
                 |----*headers*
  
       |----lib
  
            |----libavutil.dylib
  
            |----libavcodec.dylib
  
            |----libavformat.dylib
  
  |----main.cpp

  (6)compile the project.

  clang++ *.cpp -L./FFmpeg/lib/ -lavutil -lavformat -lavcodec -I ./FFmpeg/include -o main.out

  But it always fail with tip ld: library not found for -lavutil or something like this. I don’t know why. Do I need to install those libraries in /usr/local dictionary instead of host ? Or I miss some variables when configing or compiling ?

  update：I solved this problem, I copyed the links of dylib files but not dylib itself, which caused this problem. But a new problem rised, when I run the program, it tips dyld: Library not loaded: @executable_path/lib/libavcodec.dylib. Reason: image not loaded.
