I had some problems getting Gstreamer to display video on iOS. This was primarily due to a lack of examples. Here, is a modification of the gstreamer tutorials that worked for me on iOS 7.1 with gstreamer 1.2.3. The original tutorials are available on the gstreamer website

The main things that I didn't get from the tutorial were:

• gst_ios_init.h needs to be edited to include the gstreamer plugins you need. By default almost no plugins are included.

• Gstreamer for iOS provided is out of date. I used the freedesktop packages

• x_overlay has been renamed to video_overlay.

• You need a GLKView in order to support the video display.
