rails media file stream accept byte range request through send_data or send_file method

Question

I have the following problem. Sounds are hidden from the public folder, cause there are only certain Users who should have access to the sound files. So I made a certain met

Answer 1

Here is my version. I use gem 'ogginfo-rb' to calculate the duration which is required to serve ogg files properly. p.s. I always have three formats - wav, mp3, ogg.

the_file = File.open(file_path)

file_begin = 0
file_size = the_file.size
file_end = file_size - 1

if request.headers['Range']
  status_code = :partial_content

  match = request.headers['range'].match(/bytes=(\d+)-(\d*)/)

  if match
    file_begin = match[1]
    file_end = match[1]  if match[2] and not match[2].empty?
  end

  response.headers['Content-Range'] = "bytes #{file_begin}-#{file_end.to_i + (match[2] == '1' ? 1 : 0)}/#{file_size}"
else
  status_code = :ok
end

response.headers['Content-Length'] = (file_end.to_i - file_begin.to_i + 1).to_s
response.headers['Last-Modified'] = the_file.mtime

response.headers['Cache-Control'] = 'public, must-revalidate, max-age=0'
response.headers['Pragma'] = 'no-cache'
response.headers['Accept-Ranges'] = 'bytes'
response.headers['Content-Transfer-Encoding'] = 'binary'

require 'ogginfo-rb'
ogginfo = Ogg::Info::open(the_file.path.gsub(/.mp3|.wav/,'.ogg'))
duration = ogginfo.duration.to_f

response.headers['Content-Duration'] = duration
response.headers['X-Content-Duration'] = duration

send_file file_path,
          filename: "#{call.id}.#{ext}",
          type: Mime::Type.lookup_by_extension(ext),
          status: status_code,
          disposition: 'inline',
          stream: 'true',
          buffer_size: 32768
