• Mp3 streaming still download in progress

  10 mars 2018, par edadam

  I have streaming an mp3 file, from my server, while that’s not fully downloaded for the server. The client detects just the already downloaded audio length. How can I show the original length, if I know that ? Can I write it as id3 tag, for example ?

  Server : Debian, Lighttpd, Ffmpeg, bash cgi

• ffmpeg youtube livestream stops after a while

  15 janvier 2021, par ohroblot

  I'll update this question

  


  ffmpeg -version

  


  ffmpeg -version
ffmpeg version 4.3.1-4ubuntu1 Copyright (c) 2000-2020 the FFmpeg developers
built with gcc 10 (Ubuntu 10.2.0-9ubuntu2)


  


  I run this command to use ffmpeg to stream to youtube ;

  


  ffmpeg -y -threads 12 \
-loop 1 -framerate 30 -re \
-i ./1280x720.jpg \
-i ./audio.mp3 \
-video_size 1280x720 \
-vcodec libx264 -pix_fmt yuv420p \
-b:v 4500k -maxrate 5500k -bufsize 22000k \
-preset ultrafast -crf 23 -tune stillimage \
-b:a 128k -ar 44100 -ac 2 -acodec aac \
-filter_complex "dynaudnorm=f=150:g=15" \
-r 30 -g 60 \
-f flv rtmp://a.rtmp.youtube.com/live2/xxxx 2>&1 | tee _LOG


  


  The stream is excellent for 45-53 minutes then i'll get an error like this from ffmpeg :

  


  [flv @ 0x56077027cd80] Delay between the first packet and last packet in the muxing queue is 10034000 > 10000000: forcing output


  


  then youtube starts to say, no data being received and the stream will end, which it does.

  


  This is the full log : http://0x0.st/-zUH.txt

  


• How to upload a transcoded file to s3 and create a link to download it

  23 août 2016, par Dotun Longe

  I want to download a video after my module "creates" it by combining a picture and audio file. The output goes to my tmp folder. This works, but I don’t know how to access it.

  My method is to create another Paperclip attachment called "converted" and the module responsible for transcoding should also be responsible for uploading the converted video to a bucket, where I can then access it via @upload.converted.url.

  I have no idea how to go about this, and my eyes hurt from searching. If you have a better way for me to be able to download the transcoded video without this option, I will be open to it.

  Module -> videocreatingproccessor.rb :

   require 'streamio-ffmpeg'
  
   require 'fileutils'
  
  
  
   module VideoCreatingProcessor
  
  
  
   def self.convert_to_video (path_to_audio_file, path_to_image_file)
  
   movie = FFMPEG::Movie.new(path_to_audio_file)
  
   options = {video_codec: "libx264", frame_rate: 60, resolution: "960x720",
  
         x264_vprofile: "high", x264_preset: "slow", pixel_format: "720p",
  
         audio_codec: "libfaac", audio_bitrate: 32, audio_sample_rate: 44100, audio_channels: 2,
  
         threads: 2}
  
    woptions = { watermark: path_to_image_file, resolution: "960x720", watermark_filter: { padding_x: 10, padding_y: 10 } }
  
  
  
   movie.transcode("tmp/output.mp4",woptions ,options )
  
   end

  uploads_controller.rb :

   class UploadsController < ApplicationController
  
   before_action :set_upload, only: [:show, :edit, :update, :destroy]
  
  
  
   def index
  
   @uploads = Upload.all
  
   end
  
  
  
   def paudioaddress
  
   "https:" + @upload.audio.url
  
   end
  
  
  
   def pimageaddress
  
   "https:" + @upload.image.url
  
    end
  
  
  
    def show
  
    require "video_creating_processor"
  
    newvideo =    VideoCreatingProcessor.convert_to_video(paudioaddress,pimageaddress)
  
    end
  
  
  
    ....
  
    end
