RP3 & Camera v2

Having a little trouble with setting up initial setup of an RPi Camera with the Navio2 & Mission Planner.

After running both commands found on the following page:

https://docs.emlid.com/navio2/Navio-APM/video-streaming/

The RPi runs and holds on:
‘Setting pipeline to PLAYING…’
‘New Clock: GetSystemClock’

Gstreamer fails on:
‘WARNING: erroneous pipeline: could not link rtph264depay0 to videoconvert0’

I have comms via wifi from PC running Windows to RPi3.

Apologies if this topic has been covered before & thanks in advance for any advice.

Which Raspbian image you are using? Did you perform update\upgrade?

VERSION_ID="8"
VERSION=“8 (jessie)”

Yes, Update/Upgrade was run a few days ago on initial setup.

Thank you for the response.

Prepend command with sudo and you should be good to go.

Slightly different error this time:

WARNING: erroneous pipeline: no element “avdec_h264”

Running using sudo, port is confirmed as open on PC as well.

Thanks again.

windows gstreamer install do not choice “typical” …you have to choice “complete” sorry bad english
