# GStreamer-1.18.4-RPi_64-bits
## GStreamer + OpenCV on a Raspberry Pi 4
[](https://opensource.org/licenses/BSD-3-Clause)
An working example of the GStreame 1.18.4.
It works on a Raspberry Pi with an 64-bits OS.
If you want to use the new 32-bits **rpicamsrc** see https://github.com/Qengineering/GStreamer-1.18.4-RPi_32-bits
------------
## Dependencies.
To run the application, you have to:
- A Raspberry Pi 4.
- GStreamer 1.18.4 installed. [Install GStreamer](https://qengineering.eu/install-gstreamer-1.18-on-raspberry-pi-4.html)
- OpenCV 64 bit installed. [Install OpenCV 4.5](https://qengineering.eu/install-opencv-4.5-on-raspberry-64-os.html)
- Code::Blocks installed. (```$ sudo apt-get install codeblocks```)
- A working Raspicam or Webcam
------------
## Installing the app.
To extract and run the app in Code::Blocks
$ mkdir *MyDir*
$ cd *MyDir*
$ wget https://github.com/Qengineering/GStreamer-1.18.4-RPi_64-bits/archive/refs/heads/main.zip
$ unzip -j master.zip
Remove master.zip, LICENSE and README.md as they are no longer needed.
$ rm master.zip
$ rm LICENSE
$ rm README.md
Your *MyDir* folder must now look like this:
GStreamerTest64.cpb
main.cpp
------------
## Running the app.
To run the application load the project file GStreamerTest64.cbp in Code::Blocks.
Next, follow the instructions at [Hands-On](https://qengineering.eu/deep-learning-examples-on-raspberry-32-64-os.html#HandsOn).
On this [page](https://qengineering.eu/install-gstreamer-1.18-on-raspberry-pi-4.html) you can see how to make the **webcam** work.
------------
## Frame rate.
The Raspicam supports many sizes and frame rates, as you can see [here](https://www.raspberrypi.org/documentation/raspbian/applications/camera.md).
You can switch between the different options by altering the parameters in the pipeline.
As long it's a valid combination, it will work. For instance:
```
//pipeline parameters
int capture_width = 640 ;
int capture_height = 480 ;
int display_width = 640 ;
int display_height = 480 ;
int framerate = 90 ;
```
