• Can I use ffmpeg to output JPEGs to a memory stream instead of a file ?

  10 juillet 2024, par Andrew Simpson

  I have a C# app. I have 100 JPEGs (for an example).

  



  I can easily encode this into a video file.

  



  When it has finished encoding on the client app I FTP upload to my server.

  



  It would be 'neater' if I could not write the video file to a disc but instead write it to a memory stream (or array of bytes) and upload via web service perhaps ?

  



  I have checked out the ffmpeg documentation but as a C# developer I do not find it natural to understand the C examples.

  



  I guess my first question is it possible, and if so can anyone post an example code in C# ? At the moment I am using the process class in C# to execute ffmpeg.

  27 septembre 2018, par cedric -

  A partir du moment où les
  $_SERVER['HTTP_X_FORWARDED_PROTO']==='https'
  et où
  $_SERVER['HTTP_X_FORWARDED_HOST']
  et
  $_SERVER['HTTP_X_FORWARDED_PORT']
  sont renseignées tout marche très bien
  Regarde ta config et complète si besoin les valeurs manquantes, mais on ne peut pas prévoir tous les cas possibles, c’est donc à toi de gérer ça dans ton mes_options en renseignant ces variables si besoin

• rails streamio-ffmpeg does not find uploaded video files

  26 avril 2016, par Felix

  I try to make a screenshot as thumbnail of a movie while uploading.

  My code looks like this at the moment

  require 'rubygems'
  
  require 'streamio-ffmpeg'
  
  
  
   def uploadMovie
  
     @channels = Channel.all
  
     @vid = Movie.new(movies_params)
  
  
  
     @channel = Channel.find(params[:vid][:channel_id])
  
     @vid.channel = @channel
  
  
  
     if @vid.save
  
       flash[:notice] = t("flash.saved")
  
       movieFile = FFMPEG::Movie.new(@vid.video.to_s)
  
       screenshot = movieFile.screenshot("uploads/screenshot", :seek_time => 10)
  
       render :add
  
     else
  
       render :add
  
     end
  
   end

  But when I do this I got this error :

    No such file or directory - the file 'http://.s3.amazonaws.com/uploads/movie/video/7/2016-04-24_16.26.10.mp4' does not exist

  That should be okay because I upload the movies to Amazon S3 with carrierwave ...

  What’s going wrong in this case ?
