Hi, I am a new user of the BlueROV2. When I connect the ROV with my computer(which is working on Ubuntu 16.04) and I open the QGroudControl, there are no video input from the BlueROV. When I check the console output, there are error message of “VideoReceiver::start() failed. Error with gst\_element\_factory\_make(‘avdec\_h264’)”. I have used the `apt install gstreamer1.0-plugins-bad gstreamer1.0-libav` command, however it is not working. When I connect the ROV with other computer working on windows and MacOS, everything works well. Can anyone suggest a way to trace the problem? And if everything failed, how can I restore QGround Control? ---

Hi, Are you using QGC with AppImage ? Please, download the [last version here](https://github.com/bluerobotics/qgroundcontrol/releases/tag/v3.2.4-BlueRobotics-Rev6). QGC is a standalone application and no library installation should be necessary. ---

I installed the QGC from the ardusub gitbook [Installation | ardusub-gitbook](https://www.ardusub.com/getting-started/installation.html) . The most confusing part is I am using dual boot for my computer and when I run QGC on the windows 10, it works fine. But when I work on Ubuntu 16.04, the video cannot be captured from the BlueROV. ---

Hello, Can you run [these commands](https://github.com/mavlink/qgroundcontrol/tree/master/src/VideoStreaming#linux) and check if it helps? ---

Thank you for all your help. I’ve tried to install gstreamer by all these commands ```auto list=$(apt-cache --names-only search ^gstreamer1.0-* | awk '{ print $1 }' | grep -v gstreamer1.0-hybris) ``` ```auto sudo apt-get install $list ``` ```auto sudo apt-get install libgstreamer-plugins-base1.0-dev ``` However, the problem remains the same. The console keep reporting “VideoReceiver::start() failed. Error with gst\_element\_factory\_make(‘avdec\_h264’)” I am wondering if this is the configuration problem for the Ubuntu? As I can control the ROV, I am quite sure that I have established a valid connection with the ROV but not for video streaming ☹ ---

This specific issue affects video only. For some reason gstreamer is unable to create the h264 decoder node. What is your current hardware? Do you have a dedicated GPU? If so, what drivers are you using for it? ---

I have run `gst-inspect-1.0 avdec_h264` on the terminal. It returns "No such element or plugin ‘avdec\_h264’ ". I did a brief search on the internet but most of them suggested me to install the libraries which I have already installed. What will you suggest me to try next? Should I uninstall all the related gstreamer files and re-install them? ---

@williangalvani @patrickelectric @jwalser Thank you for all your help. I have reinstall the whole system and with the libraries installed, it works! 😄 ---

I am glad you managed to get it working. I tested in a Ubuntu 16.04 VM here and all it took was `apt install gstreamer1.0-plugins-bad gstreamer1.0-libav`. Maybe something got corrupted in your install. If you see something like this again, I suggest reinstalling the packages above using the same command with the `--reinstall` flag. ---
