EBC Exercise 29 GStreamer
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.
- Get the updated files from the git repository
beagle$ git clone firstname.lastname@example.org: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
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.
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
