• FFmpeg error - “at least one output file must be specified” windows version

  30 juin 2016, par AComputert

  I’m having a little trouble, and I feel like the solution is probably starting me in the face.
  How Can I extract mp4 from HTTP live streaming m3u8 file ? I Tried this command below :

  ffmpeg -i http://ms1.movieland.ir/marci6z9OSicn34CRRcin2y4nv6KRZvigAIBsBbBGlj2HUPZBeEOY1019Zxc6zlQrq3ZkYrW0PiM1WDbpVn2JQ2/vod/5787c62c-fb29-4ca4-a328-b7447bb83436/medialist.m3u8?rpt=%5C2016%5C6%5C5787c62c-fb29-4ca4-a328-b7447bb83436&pid=0 -c copy -bsf:a aac_adtstoasc f:\stream\dora.mp4

  When run, this yells at me that "At least one output file must be specified". I’ve been knocking me head on the wall for hours now, what am I missing ?

• 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
