Ruby Library hpricot

jphillips — Thu, 22 Oct 2009 13:55:08 +0000

hpricot provides a nice dom traversal library for web scraping. When using hpricot to parse xml docs, I discovered that Hpricot automatically downcases xml nodes. XML files generated by Microsoft Excel generate nodes with capital letters.

example:

becomes:
doc:/workbook

kind of a small thing, that I’m documenting for myself.

New hulu styled open source video player.

jphillips — Wed, 29 Oct 2008 13:54:57 +0000

Just created this open source video player styled like hulu. It’s adapted and rewritten code from: http://chrisbrimelow.com/blog/?p=15 . Some of the changes I made were pretty basic including separating the ui from some of the nitty gritty stuff that drives the video. There’s also file streaming capabilities built into the player.

To take advantage of streaming video, I’m running nginx with flv-streaming-module compiled into my install. Seems to work pretty well and handles tons of connections simultaneously.

Source code on github for this video project is located here: http://github.com/elguapo1611/opthumb-videoplayer/tree/master

Batch video conversion with ffmpeg and Ruby

jphillips — Wed, 22 Oct 2008 19:29:13 +0000

Decided to write a simple script for exporting all my video content to streaming .flvs:

in batchconvert.rb

path = “.”
#contains = Dir.new(basedir).entries
videos = Dir["#{path}/*.mov"]
videos.each do |f|
puts “converting #{f}”
newFile = f.gsub(“.mov”, “.flv”)
system(“ffmpeg -i #{f} -ar 22050 -s 640×480 -b 500000 #{newFile}”)
system(“flvtool2 -U #{newFile}”)
end

To run this command, open up the Terminal and navigate to your video directory. Then run:

ruby batchconvert.rb

This script doesn’t include any switches or options for files other than .movs.
