Build GStreamer for Debian

The source code should be placed on the board, and make sure that the debian/ directory exists in the root directory of the source code.

Enter the source root directory and execute the following procedure:

Use the following command to update software resources.
```
apt update
```
Use the following command to install library dependencies.
```
apt build-dep
```
(Optional) Use the following command to start build the Debian installation package.
```
dpkg-buildpackage -b -d -uc -us
```
Result: After the building is completed, the Debian installation package will be generated in the upper directory, which can be installed by using dpkg -i xxx.deb.
Build and install.
```
meson build && ninja -C build install
```

It is generally recommended to use the first way to build the Debian installation package, which can ensure that the options such as compilation and installation are unified.

Note: Some compilation options depend on the macro definitions in header files such as video-format.h, so you need to install the libgstreamer-plugins-base1.0-dev package first to ensure the headers such as video-format.h to the latest and ensure that certain features are turned on.
