There are many open source efforts that run on desktop Linux that have been ported to the BeagleBoard. You can see many here. One effort is GStreamer a library for constructing graphs of media-handling components, or more simply, a open source multimedia framework.
Here are some audio and video demos based on a RidgeRun talk at ESC.
Getting Started
- Get the updated files from the git repository
beagle$ git clone git@github.com:MarkAYoder/BeagleBoard-exercises.git exercises
or if you've already git'ted them, make sure you have the most up to date versions.
beagle$ cd exercises beagle$ git pull
Audio Demos
There are several scripts that show what GStreamer can do. They all begin with a'.
beagle$ cd gstreamer beagle$ ./a2
Go try all the audio files. Make a note (1 or 2 sentences max) about what each one is showing.
a5 is an audio through demo. I've set it up to take input from the PS EYE mikes, but I don't hear anything coming out. Can you make it work? Don't take more that 5 minutes.
Video Demos
The files beginning with v are video demos.
- Try them and make a note about what each does.
- v5 is video through, so you'll need the PS EYE. Use gst-inspect to learn what v4l2src can do. Modify v5 to use a image that half the size.
- v6 and v7
