GStreamer won't show video

Question

I ran Gstreamer tutorial's example code in both my own 2 computers.

• One PC was install Ubuntu 20.04.2, GPU Nvidia GTX 1050Ti
• And the remain one (i.e laptop) was install Ubuntu 18.04.5, with NVIDIA GeForce GTX 950M

And the result when built successfully ./basic-tutorial-1 was:

• the ubuntu 20 PC can show the video in the display.
• but the ubuntu 18 laptop is not display anything, or even any error logs.

Is there any Gstreamer's problem relate to OS.

Answer 1

There might be an issue with installation:

try:

sudo apt install gstreamer1.0-tools
sudo apt install gstreamer1.0-plugins-base
