• ffmpeg sometimes only creating one segment for the entire HLS playlist regardless which -hls_time i use [closed]

  10 mai 2023, par kusti420

  can someone explain why it works as it should with certain FLACs and with other ones it only creates one m4s segment and how to fix it where it would actually create one segment every 6 seconds for any flac, as it should with "-hls_time 6".

  


  ffmpeg -i .\audio4.flac -c:a flac -vf pad="width=ceil(iw/2)*2:height=ceil(ih/2)*2" -ar 96000 -f hls -hls_time 6 -hls_playlist_type vod -strict -2 -hls_segment_type fmp4 -hls_segment_filename "idk%d.m4s" playlist.m3u8

  


  when it doesnt work then logs print out like over thousand lines of :
[hls @ 0000026653933a00] Delay between the first packet and last packet in the muxing queue is 10069334 > 10000000: forcing output

  


  i tried different versions of ffmpeg, running it on different devices and on different operating systems
was obviously expecting it to work the same for all flacs, but more than half the time it just isnt working as it should

  Fix chrome valgrind warning due to the use of mismatched bsize

  This commit fixes a mismatched use case of block size in non-RD
  intra prediction check. The residual SSE and variance should be
  calculated per transform block size, instead of operating block
  size, which caused chrome valgrind warning on conditional jump
  based on uninitialized value (webm issue 823). This commit
  resolves this issue.

• Load processed video instead of original video - Rails, Dragonfly

  1er février 2016, par Michael B

  In my Rails 4-Project, I am using Dragonfly to upload images and videos.
  For image-processing I use imagemagick, for videoprocessing I use ffmpeg.

  Videos are uploaded and stored in the folder uploads/videos. After processing, they are stored in public/ffmpeg_videos/

  My question is : How can I use the processed-video instead of the uploaded video ?

  e.g. I use this code in the view, to display a video :

  <video src="&lt;%=@video.video.url%>"></video>

  This successfully loads the original video from the upload-path. But what do I have to change, to load the video from the ffmpeg-path ?

  initializers/dragonfly.rb

  require 'dragonfly'
  
  
  
  # Configure
  
  Dragonfly.app(:images).configure do
  
    plugin :imagemagick
  
    protect_from_dos_attacks false
  
    secret 'd045734b043b4383a246c5c8daf2d3e31217dc8b030f21861e4fd16c4b72d382'
  
    url_format '/media/:job/:name'
  
  
  
    datastore :file,
  
              root_path: Rails.root.join('uploads/images/'),
  
              server_root: Rails.root.join('uploads')
  
  end
  
  
  
  Dragonfly.app(:videos).configure do
  
    secret 'd045734b043b4383a246c5c8daf2d3e31217dc8b030f21861e4fd16c4b72d382'
  
    url_format "/video/:job/:name"
  
  
  
    datastore :file,
  
              root_path: Rails.root.join('uploads/videos/'),
  
              server_root: Rails.root.join('uploads')
  
  end
  
  
  
  # Logger
  
  Dragonfly.logger = Rails.logger
  
  
  
  # Mount as middleware
  
  Rails.application.middleware.use Dragonfly::Middleware, :images
  
  Rails.application.middleware.use Dragonfly::Middleware, :videos
  
  
  
  # Add model functionality
  
  if defined?(ActiveRecord::Base)
  
    ActiveRecord::Base.extend Dragonfly::Model
  
    ActiveRecord::Base.extend Dragonfly::Model::Validations
