Heroku ffmpeg buildpacks for video uploads

Question

Is there a proper way to get heroku ffmpeg installed and running so that my users can upload videos in my rails app?

Tried the Heroku references on the topic which led to my app running the heroku error check logs page...

I know there has to be some installation I have to pass but don't seems to find anything on it - Please help with links or ideas :)

Got heroku Video uploads to work!

Video model:
    has_attached_file :video, styles: {
        :medium => {
          :geometry => "640x480",
          :format => 'mp4'
        },
        :thumb => { :geometry => "160x120", :format => 'jpeg', :time => 10}
    }, :processors => [:transcoder]
    validates_attachment_content_type :video, content_type: /\Avideo\/.*\Z/

Make sure you already bundled:

gem 'paperclip', '~> 4.3.1'
gem 'aws-sdk', '< 2.0'
gem 'paperclip-av-transcoder'

Run the paperclip migration:

rails g paperclip model video

Be sure to add in post_controller.rb:

private

    def bscenes_params
        params.require(:post).permit(:video)
    end

Upload form:

<%= f.file_field :video %>

Show page:

<%= video_tag bscene.video.url(:medium), controls: true, style: "max-width: 100%;" %>

At this point you should get this error:

Av::UnableToDetect (Unable to detect any supported library):

Go to your terminal and type in:

brew options ffmpeg

Then run the following to install ffmpeg:

brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libas

At this point video uploads will work locally

Now for remote uploads you will need to setup https://devcenter.heroku.com/articles/buildpacks

After setting up Heroku buildpacks you may get an error:

Av::UnableToDetect (Unable to detect any supported library)

You will need to create a Procfile in the root of your app directory more information about Procfile here: https://devcenter.heroku.com/articles/procfile

touch Procfile

Hope this helps!

users can upload videos

We've had it working on Heroku before; we used paperclip-ffmpeg (which is now paperclip-av-transcoder) with the actual Paperclip gem.

Whilst I can't provide any information about the buildpacks, I can share how we were able to get video uploading working on Heroku...

#app/models/attachment.rb
class Attachment < ActiveRecord::Base
    has_attached_file :attachment,
    styles:     { thumb: { geometry: "100x100#", format: 'jpg', time: 10}, medium: { geometry: "300x300#", format: 'jpg', time: 10} },
    processors: [ :transcoder ]
end

As long as the paperclip-av-transcoder gem installs (ensure you've got it in your Gemfile), this should allow you to store the videos - and images - you need.
