Create the gstreamer plugin step by step

1. Obtain the template GST-template for creating the plug-in.

Method 1: CVs
$ CVS-D: pserver: anoncvs@cvs.freedesktop.org/CVS/gstreamer Login
Password: [Root Password]
$ CVS-Z3-D: pserver: anoncvs@cvs.freedesktop.org:/CVS/gstreamer Co GST-template

Method 2: git
If git is not installed, install git first:
$ Sudo apt-Get install Git-core
Then obtain the template:          
$ Git clone git: // anongit.free?top.org/gstreamer/stp-template.git

2. Go to the directory GST-template/GST-plugin/src.
$ Cd gst-template/GST-plugin/src
$ ../Tools/make_element examplefilter
(Pay attention to the sequence here, otherwise the compilation will fail to find the stststplugin. c error)
Generate files
Gstexamplefilter. c gstexamplefilter. h

3. Modify the makefile. Am file (Note: makefile. AM in the src directory)
$ Sudo gedit makefile. AM

Plugin_ltlibraries = libstexamplefilter. La

Libststexamplefilter_la_sources = maid. c

Libststexamplefilter_la_cflags = $ (ststst_cflags)
Libststexamplefilter_la_libadd = $ (ststst_libs)
Libststexamplefilter_la_ldflags = $ (ststst_plugin_ldflags)
Libststexamplefilter_la_libtoolflags = -- tag = Disable-static

Noinst_headers = maid. h

There are seven rows in total

4. Import the pkg_config_path environment variable and enter the following in the command line:

$ Export pkg_config_path =/usr/lib/pkgconfig

5. Go to the directory GST-template/GST-plugin and modify the file autogen. Sh.
Go to the directory at the previous level
$ CD ..
Edit the autogen. Sh file:

$ Sudo
Gedit autogen. Sh

(The following error may occur: Can't.
Exec "libtoolize": No file or directory at/usr/bin/autoreconf line 196. Solution: APT-Get install libtool)

If the template is obtained through CVs, modify the original
Srcfile = src/Main. c
New:
Srcfile = src/gstexamplefilter. c

If the template is obtained through git, add it at the beginning of autogen. sh:
Srcfile = src/gstexamplefilter. c

6. Run autogen. Sh to generate the MAKEFILE file.

$./Autogen. Sh

7. Start installation:
$./Configure
$ Make
$ Sudo make install

Go to the SRC subdirectory.
$ CD SRC

The. libs directory will be generated during LS-a query.
(Note:. libs is a hidden directory)
Enter. libs
$ Cd. libs
$ LS-

You will find that

Libststexamplefilter. La
Libststexamplefilter. So

8. Add the plug-in to the gstreamer library.
Put libststexamplefilter. La
Libststexamplefilter. So
These two files are copied to the system directory:/usr/lib/gstreamer-0.10

$ Sudo CP libstexamplefilter. La/usr/lib/gstreamer-0.10/libststexamplefilter. La

$ Sudo
CP libststexamplefilter. So/usr/lib/gstreamer-0.10/libststexamplefilter. So

(There seems to be no need to copy here, and there are these two files under the gstreamer-0.10 directory)

Check the plug-in:
$ GST-inspect examplefilter

If the plug-in information is displayed, the plug-in is created.
