I have downloaded the latest version of Raspbian today, in the hope of being able to download and use GStreamer.

I need to use GStreamer to stream video across to another computer with minimal delay, currently I am achieving a delay of 2 seconds via VLC player. I need to have minimal if not any delay for the project (eyes for controlling a Lynxmotion Tri-Track robot running with a BotBoarduino).

Using this tutorial I have reached the step of adding deb http://vontaene.de/raspbian-updates/ . main to /etc/apt/sources.listand then sudo apt-get update however the following error occurs:

GPG error: http://vontaene.de. Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY

This error is preventing me from being able to install GStreamer.

Just to make sure that nobody looses two hours trying to fix this. You do not need to change anything in the sources.list anymore.

Install GStreamer with:

sudo apt-get install gstreamer1.0-tools

You need to install the debian-keyring. Then replace the key 1F41B907 in both placed below with the key that shows up after the "NO PUBLIC KEY" from the end of the update list. I'm still getting a package error but I think it is just an error in my /etc/apt/sources.list:

sudo apt-get install debian-keyring
gpg --keyserver pgp.mit.edu --recv-keys 1F41B907
gpg --armor --export 1F41B907 | sudo apt-key add -
