GStreamer element cannot be created: no element textoverlay ?

[piwpiw]

Hi community,

I'm trying to create a GStreamer element on Kurento with the following command : 

    Command : textoverlay text="Room A"

But I'm getting the error : 

    GStreamer element cannot be created: no element textoverlay ?

Am I missing a plugin or something ? Does anyone know how to solve that please ?

Thank you in advance for your help.

Regards,

[Juan Navarro]

Is that a local install? (with apt-get install) or a Docker container? (docker run)

please try installing this package: gstreamer1.5-x

$ sudo apt-get update && sudo apt-get install --yes gstreamer1.5-x

Thanks for your answer Juan.

I don't know actually. I have the version of Kurento that I installed from AWS Cloud Formation Template Here : https://doc-kurento.readthedocs.io/en/latest/user/installation.html#amazon-web-services

I run the command but I'm still getting the same error. Do you know how to add this plugin please ?

Thanks.

You used the AWS CF template, which creates a new EC2 machine in your AWS account. So, just get an admin terminal to that machine (with the AWS console or just connecting with SSH from your computer), and run in there the apt-get command I suggested.

That's exactly what I did Juan. Running the command from ssh :  $ sudo apt-get update && sudo apt-get install --yes gstreamer1.5-x

But I'm still getting the same error. 

Do you what can cause this please ?

Thanks

I can think of a couple checks:

• Also install package "gstreamer1.5-tools", and then run "gst-inspect-1.5" to verify if the textoverlay plugin is correctly installed. You should see something like this:
  
  $ gst-inspect-1.5 | grep textoverlay
  pango:  textoverlay: Text overlay
  
  
• Install package "kms-datachannelexample", and run the Java - Show DataChannel tutorial. This tutorial uses the textoverlay plugin to write text on top of the remote video. This would be a good way to ensure that the plugin itself is working with Kurento.
  
  
• I found this message: https://github.com/Kurento/bugtracker/issues/78#issuecomment-502695184
  which seems to imply that the valignment and halignment parameters don't work well, but I didn't verify if that's true or not. Still, you might want to simplify your plugin config to the bare minimum, to see if it works (no parameters at all), before using any additional parameter.
