Add in gstreamer? X265 codecs

The official gstreamer version does not support x265 encoding/decoding? X265, You need to compile it yourself. This article is based on gstreamer1.3.3. You must first compile gstreamer1.3.3 and the corresponding base, good, bad, and uugly plug-ins.

1. Install and compile the x265 Encoder

1. Download the source code.

Open source x265 encoder official site is https://bitbucket.org/multicoreware/x265/wiki/Home

Source code: Hg clone https://bitbucket.org/multicoreware/x265

Of course, you must first install the Hg source code management tool, which is similar to git and comes with this tool in Debian 7. Its name is mercurial.

2. Install the compiling environment:

Sudo apt-Get install cmake-Curses-Gui build-essential

3. Debian 7 assembly software yasm version is 1.1, x265 Assembly compilation requires 1.2 version, so you need to compile yasm1.2

: Http://yasm.tortall.net/releases/Release1.2.0.html

After compilation, configure the environment variable path so that yasm1.2 runs first.

4. Compile x265

Go to the build/Linux folder and run:

/Make-Makefiles.bash

A character configuration interface is displayed, and the number of characters is changed based on your needs.

Then make and install.

At this time, the x265 command should be able to run and try to find a y4m original video file to encode it.

5. Compile and install the gstreamer x265 plugin

: Https://bugzilla.gnome.org/show_bug.cgi? Id = 726376

The bug attachment is the patch file. The author did not specify the version number based on which gstreamer is written, but the location is in the bad plug-in of gstreamer. To use this patch for your gstreamer version, you must compare the code and modify the patch according to your version number. I made changes based on the gstreamer1.3.3 version. The attachment contains my change file .. For details about how to use patch files, refer to relevant documents. After the patch, several bugs need to be changed. My patch files

After the patch, the bad plug-in includes the x265enc plug-in. In the EXT/x265 folder.

Compile and install the entire bad plug-in again.

Use the gst-inspect-1.0 | grep x265 should be able to see the x265enc plug-in. The plug-in usage is basically the same as the x264enc usage. Of course, the current function is still very preliminary, but the main x265 encoding has been completed.

Ii. Install the x265 Decoder

1. Install libde265

: Https://github.com/strukturag/libde265

Make and install

2. Install gstreamer-libde265

: Https://github.com/strukturag/gstreamer-libde265.git

Dependent on libbz2

Use autogen. Sh to configure

Make installation.

Set the installation location to the environment variable gst_plugin_path.

Iii. Trial and use

Please refer to my blog for another common gstreamer pipeline command.
