GStreamer 源码 Meson 编译 1.20¶

版本与环境介绍

GStreamer version : 1.20

Ubuntu : 18.04

1. 下载 GStreamer 源码¶

git clone -b 1.20 https://gitlab.freedesktop.org/gstreamer/gstreamer.git

这里下载1.20版本

2. 配置¶

不指定option的情况下，执行meson，会按默认的规则编译，是不带libav，x264的。

cd gstreamer
meson build

meson configure | grep 264可以查看是否编译进去；

 pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer$ meson configure | grep 264
 libopenh264          auto               [enabled, disabled, auto]    libopenh264
 libx264            auto               [enabled, disabled, auto]    libx264
 openh264            auto               [enabled, disabled, auto]    H.264 video codec plugin
 uvch264            auto               [enabled, disabled, auto]    UVC compliant H.264 camera source plugin
 x264              auto               [enabled, disabled, auto]    H.264 video encoder plugin based on libx264 (GPL - only built if
 x264_libraries                                          Colon separated list of additional x264 library paths, e.g. for

Subproject openh264:

指定reconfigure

meson --reconfigure build

指定安装目录

meson --reconfigure build --prefix=/mnt/work/zheng/gstreamer/gstreamer/install

3. 编译¶

ninja -j36 -C build

4. 安装¶

安装

meson install -C build

5. 虚拟环境测试¶

pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer$ cd build/
pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer/build$ ls
build.ninja compile_commands.json GstDocumentedSubprojects GstPluginsPath.json meson-info meson-logs meson-private meson-uninstalled subprojects tests
pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer/build$ ninja devenv
[0/1] Running external command devenv (wrapped by meson to set env)
[gst-1.20] pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer/build$

6. 遇到问题¶

6.1 Python 版本切换¶

# 查看有哪些版本
ls /usr/bin/python*
# 设定：
alias python=/usr/bin/python3.8
alias python3=/usr/bin/python3.8

再更新为3.7

pub@ubuntu64:/mnt/wo rk/zheng/gs t reame r/gs t reame r$ pub@ubuntu64:/mnt/wo rk/zheng/gs t reame r/gs t reame r$ pub@ubuntu64:/mnt/wo rk/zheng/gs t reame r/gs t reame r$ pub@ubuntu64:/mnt/wo rk/zheng/gs t reame rigs t reame r$ python 3.7.5 alias python=/us r/bin/python3.7 python - - ve rs Ion

6.2 Meson 版本¶

sudo apt-get install meson

版本需要0.60以上，发现版本不对

pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer$ meson --version
0.45.1
pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer$ pip3 install --user meson

pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer$ meson --version
0.45.1

发现版本还是不对；

[原因: 继续搜索发现pip3会将软件安装到/home/user/.local/bin 而系统默认是使用/usr/bin/meson]

设置环境变量

pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer$ export PATH=~/.local/bin:$PATH
pub@ubuntu64:/mnt/work/zheng/gstreamer/gstreamer$ meson --version
0.61.4

正常

部分需要修改root 用户相关的版本

$ git clone -b 1.20 https://github.com/GStreamer/gst-rtsp-server.git
meson --reconfigure build --prefix=/home/mhpub/gstreamer/gst-rtsp-server/build/out
