• Live website to video

  25 janvier 2016, par Asaf Nevo

  I have a website which shows a slideshow of pictures using JS.

  The pictures objects are coming from a web service and are being updated from time to time.

  In few days, I doing a test with a potential client to present the pictures slideshow on his big LED screen.

  He’s using BSPlayer for the content on screen, an able to present a website, but it will never be a clean full screen (the X button and such will always be presents).

  He’s the most comfort with presenting a video rather than a website.

  One of my ideas of solutions was to check if there is a way to stream a content of a website.

  Googling it got me to a solution combined ImageMagic and FFMPEG which you can read about here

  My problem is that this solution only creates a slide show out of static pictures - which I can do, but i’m losing the dynamic part of my live slideshow.

  Is there a tool for capturing websites and converting them into a stream of videos ?

  Or maybe a workaround to achieve the same functionality ?

• Google Speech to Text on WAV file gives

  7 janvier 2021, par Darth.Vader

  I am using the Google Speech to Text API to convert a WAV file to text. When I play the WAV file, it works fine but when I run the Google Speech To Text API I get this error :

  


  WAV header indicates an unsupported format.


  


  When I try to analyze the file using ffmpeg tool, it get the following error :

  


  Output #0, wav, to '/home/shubham/workspace/intent-service/scripts/audio2.tmp.wav':

  What am I missing ?

  


• creating a modern nodejs video rendering app (ffmpeg microservice / cloud hosting)

  5 avril 2020, par Martin

  I'm thinking of making a nodejs website like tunestotube.com or audioship.io that will :

  



  


  • accept an audio file / image file input

  


  • render a video using ffmpeg

  


  • upload that video to youtube

  


  



  I just have a question on the best way to go about doing this, I want to host over GCP eventually, and am thinking about the best / most efficient way to handle the ffmpeg video rendering, since I want it to be scaleable and have a load balancer (ingress ?) queue to handle getting multiple requests at once.

  



  Would it make sense to containerize my web service ? Have the main website be one docker image ; and have another image / microservice 'video-renderer' that would accept the inputs, render the video, and return the rendered video ?

  



  Does this idea make sense, and would going about it in the way I describe above work ? I'm also trying to find tutorials / example projects with handling microservices / load balancers in node js / gcp if anyone has any ideas / recomendations, thanks
