• compile ffmpeg on ec2 linux instance - no libfdk-acc available

  11 mai 2022, par byc

  I’m compiling the ffmpeg on an ec2 amazon linux instance, but it threw me an error ERROR: libfdk_aac not found.

  


  I'm following this guide http://trac.ffmpeg.org/wiki/CompilationGuide/Centos to first install the dependencies and compile the package.

  


  yum install autoconf automake bzip2 bzip2-devel cmake freetype-devel gcc gcc-c++ git libtool make pkgconfig zlib-devel

mkdir ~/ffmpeg_sources

cd ~/ffmpeg_sources
curl -O -L https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg

make
make install
hash -d ffmpeg


  


  and this is the error message I've got

  I tried installing libfdk_aac but there's no package found. I don't seem to come across any posts discussing this issue, or at least recently. Appreciate any pointers. thanks !

• Rails using stremio-ffmpeg gem to watermark a movie while uploading

  16 juin 2016, par Felix

  I am using carrierwave to upload a movie to amazon s3 that works perfect.

  Now I want to add a watermark to the movie while uploading or after uploading, I don’t know, what’s the best way ?

  I tried this :

  movie_controller.rb action uploadVideo

  movie = FFMPEG::Movie.new(@vid.video.url)
  
  
  
  puts "........................................"
  
  puts movie.inspect
  
  
  
  if @vid.save

  Just to find out if the video is catched from stremio.

  But then I got the error that the movie is not found, the problem is that it doesn’t look in the amazon s3 bucket, it looks on my local server

  No such file or directory - the file '/uploads/tmp/1462954331-3471-8766/VID-20160424-WA0013.mp4' does not exist

  What could be the solution ? or should I do this in carrierwave uploader ?

  UPDATE :

  When I do this after the .save action it looks at amazon s3 bucket .. but also says that the movie isn’t there. But if I call it directly in browser it’s displayed.

  UPDATE Code :

  #Laedt ein Video hoch
  
  def uploadMovie
  
    @user = User.find_by_id session[:user_id]
  
    #Holt alle Channels für die er eine Berechtigung hat (Eingeloggter user)
  
    @user = User.find_by_id session[:user_id]
  
    @knowledgeproviderList = @user.knowledgeprovider
  
    @channels = Channel.where(knowledgeprovider_id:     @knowledgeproviderList.pluck(:id))
  
    @vid = Movie.new(movies_params)
  
    @channel = Channel.find(params[:vid][:channel_id])
  
    @vid.channel = @channel
  
  
  
    #Fügt dem Movie einen Tag hinzu
  
    createTag params
  
    createCategory params
  
  
  
  
  
  
  
    if @vid.save
  
      flash[:notice] = t("flash.saved")
  
  
  
      #movie = FFMPEG::Movie.new(@vid.video.url)
  
  
  
      #puts "........................................"
  
      #puts movie.inspect
  
  
  
      redirect_to :action => :add
  
     else
  
       redirect_to :action => :add
  
    end
  
   end

  Update error :

  movie = FFMPEG::Movie.new(@vid.video.current_path)
  
  
  
  options = {watermark: "mages/header.png", resolution: "640x360", watermark_filter: { position: "RT", padding_x: 10, padding_y: 10 } }
  
  movie.transcode("movie.flv", options)

  

  Update :
  Added the code in the uploader :

    process :watermark_movie
  
  
  
       def watermark_movie
  
         if self.file.path
  
               options = {watermark: "images/header.png", resolution: "640x360", watermark_filter: { position: "RT", padding_x: 10, padding_y: 10 } }
  
               self.model.file = FFMPEG::Movie.new(self.file.path).transcode("#{root}/#{cache_dir}/#{self.cache_id}/file.mp4", options)
  
          end
  
        end

• AWS Lambda function for modify video

  4 février 2017, par Gold Fish

  I want to create a Lambda function that invoked whenever someone uploads to the S3 bucket. The purpose of the function is to take the uploaded file and if its a video file (mp4) so make a new file which is a preview of the last one (using ffmpeg). The Lambda function is written in nodejs.
  I took the code here for reference, but I do something wrong for I get an error saying that no input specified for SetStartTime :

  //dependecies
  
  var async = require('async');
  
  var AWS = require('aws-sdk');
  
  var util = require('util');

                  );
  
              }
  
  
  
              callback(null, "message");
  
          }
  
      );
  
  };

  So what am I doing wrong ?
