Ruby Ming Extension Patch to Add Video Streaming

After playing with the Ruby Ming extension a little more I found that they don’t have support for SWFVideoStreams so I made a patch to add it. The patch also fixes the beta issues I described in building the ming ruby extension.

Here are the steps you need to follow to patch and install the latest Ming Ruby extension:

  • Download the 0.1.7 version from: wget
  • Uncompress the archive file: tar xvzf ming-ruby-0.1.7.tar.gz
  • Change into the source directory: cd ming-ruby-0.1.7
  • Download the new SWFVideoStream file and stick it into the ext/ming/mingc directory: wget -O ext/ming/mingc/swfvideostream.c
  • Download the patch: wget
  • Apply the patch: patch -p0 -u < patch
  • Run the setup script: ruby setup.rb

If you want the source and patch by themselves you can find get those from: swfvideostream.c and patch

And here is an example of using the SWFVideoStream to embed a Flash video into your Flash movie:

[code lang=”ruby”]
#!/usr/bin/env ruby

require ‘ming/ming’
include Ming


m =
m.set_background(0xff, 0xff, 0xff)
m.set_dimension(320, 240)

vstream =‘test.flv’)
vstream.set_dimension(320, 240)


0.upto(vstream.get_num_frames) do

The above example assumes you have a Flash video file available named test.flv. If you don’t have one you can make one by reading about creating flash videos with FFMpeg.
