Just some experimentation in creating a live transcoding HTTP Live Streaming server for accessing an HDHomeRun

gistfile1.sh

ffmpeg -i http://PRIMEIP:5004/auto/v1004  -async 1 -ss 00:00:05 -acodec libfdk_aac -vbr 3 \
-b:v \3000k -ac 2 -vcodec libx264 -preset superfast -tune zerolatency  -threads 2 -s 1280x720 \
-flags -global_header -map 0:0 -map 0:1 -f segment -segment_time 10 -segment_list stream.m3u8 \
-segment_format mpegts -segment_wrap 10 -segment_list_size 6 -segment_list_flags live stream%03d.ts

server.rb

require 'rubygems'
require 'sinatra'
require 'open-uri'


get '/test.m3u8' do
  content_type 'video/MP2T'
  open('test.m3u8').read
end

get %r{/(stream\d+.ts)} do
  content_type 'application/x-mpegURL'
  open(params[:captures].first).read
end
