• FFMPEG - Codec Copy transcoded audio from first output transport stream to other transport streams

  27 mars 2019, par Software Development Consultan

  I am currently trying to generate 3 output Transport streams from single input stream, for this I need to do Video encoding for each output as I wanted to have different bitrate for each stream. But for audio stream I have same audio bitrate and same params for all 3 output Transport stream.
  So I want to somehow transcode audio only first time (in first stream, let say from AC3 to AAC) and then just want to copy output transcoded audio from first output (aac) to other 2 outputs. so that will save processing power.

  I have setup overall command for this, but for audio copy I am not able to set so that I can get output audio from first Transport stream output

  Please refer following command :

  I want to have output stream "239.1.1.222:2222" and "239.1.1.222:3333" should have copied audio stream (AAC) from first output stream "239.1.1.222:1111" and Not from main input stream "239.1.1.111:1234"

• 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.
