Raspberry Pi dependency package authentication warning

arm
#1

Hi! There is something wrong with the ./install_dependencies.sh script as it stops at a point and throws out this:

WARNING: The following packages cannot be authenticated!
libgstreamer1.0-0 liborc-0.4-0 libgstreamer-plugins-base1.0-0 gstreamer1.0-omx libgstreamer-plugins-bad1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gir1.2-gstreamer-1.0 gir1.2-gst-plugins-base-1.0 gstreamer1.0-alsa gstreamer1.0-plugins-good gstreamer1.0-pulseaudio gstreamer1.0-x libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev

I tried to install different versions of those, libgstreamer0.10-0 (replaced all 1.0 with 0.10). I was able to install everything except gstreamer1.0-omx (it was also not possible to find an alternative version with apt-cache search).

oF compiled fine, but then I had problems with launching the opencvExample project. It compiled and launched fine, except it had problems with ofGstVideoUtils:

[warning] ofGstVideoUtils: update(): ofGstVideoUtils not loaded

I will try to launch the opencvExample on my old RPi oF system that was made about 3 months ago and did not have any dependency problems and see what happens, but maybe someone has faced the same issue and knows what could be wrong there?

I’m using 2014-01-07-wheezy-raspbian.img

The same happens if I clone the master branch from the oF github repo.

OF on the rPI depends on the omx package to decode h264 so unless you install it you won’t be able to use video files with that format. you can use 0.10 but it won’t do hardware decoding (that’s what omx does) and will be too slow

the authentication error, is ok just answer yes when it asks you and it’ll install 1.0 without problem

#3

Could it be that there is some problem with the repo? One or more of the packages missing or so? Because I’m answering yes, but anyway I get the error and the packages are not being installed.

#4

this is the repo address - I am able to get to it at this moment so it should be ok

@arturo actually I don’t think gstreamer will use the omx pipeline unless it is explicitly setup. The main reason that we we required gstreamer 1.0 is that playing video caused segfaults with the gstreamer .10 setup and OF 8.0

When the new version of Raspbian (Jessie) is released we will be able to drop the 3rd party repo

#5

Ok. I got it working eventually - I was pressing ‘Return’ instead of ‘y’ + ‘Return’ when prompted to install unverified packages. But good to know about the reasons of choosing 3rd party repo.
