GStreamer 源码 Meson 编译 1.24¶

版本与环境介绍

GStreamer version : 1.24

Ubuntu : 22.04

1. 下载 GStreamer 源码¶

$ cat /proc/version
Linux version 6.5.0-44-generic (buildd@lcy02-amd64-103) (x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0, GNU ld (GNU Binutils for Ubuntu) 2.38) #44~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Jun 18 14:36:16 UTC 2

 git clone -b 1.24 https://gitlab.freedesktop.org/gstreamer/gstreamer.git

这里下载1.24版本

2. 依赖相关包安装¶


python3	>= 3.8
ninja	>=
meson	>=1.1

2.1 部分包安装¶

为了解决后续配置编译问题还需要安装【不然出现错误】：

sudo apt install flex bison

可选依赖包

sudo apt-get install libxv-dev libasound2-dev libtheora-dev libogg-dev libvorbis-dev libbz2-dev libv4l-dev libvpx-dev libjack-jackd2-dev libsoup2.4-dev libpulse-dev faad libfaad-dev libfaac-dev libx264-dev libmad0-dev yasm

2.2 安装 Meson 和 Ninja¶

sudo apt install python3-pip

更新meson 版本

pip3 install meson==1.3.1 --break-system-packages

3. 配置编译安装¶

3.1 配置编译¶

# 配置
meson setup builddir
# 推荐！！！！配置安装指定路径
mkdir _install
meson setup --prefix=/home/hywelstar/Develop/gstreamer/_install builddir

# 编译
meson compile -C builddir

假如需要安装指定目录可以选择一下方式：

# ===============以下可选择==============
# 更换安装目录方法：
# 首次配置的话采用
meson setup --prefix=/home/hywelstar/Develop/gstreamer/_install builddir
# 中途更改安装到指定路径
meson setup  builddir --reconfigure  --prefix=/home/hywelstar/Develop/gstreamer/_install
# =====================================

配置完成：

编译

meson compile -C builddir

3.2 安装¶

meson install -C builddir

看到下图表示安装成功

4. 环境测试¶

运行gst-env.py 将带你进入刚刚编译的那个环境

./gst-env.py

## 本工程使用这个
./gst-env.py --builddir builddir

## 或者这个代替
ninja devenv

测试命令：

$ gst-inspect-1.0 --version
gst-inspect-1.0 version 1.24.6
GStreamer 1.24.6 (GIT)

图像测试【如果出现错误，请跳转配置参数章节】：

GST_DEBUG=3 gst-launch-1.0 videotestsrc ! autovideosink

5. 问题解决¶

5.0 网络问题代理¶

git config --global user.name "hywelstar"
git config --global user.email "hywelstar@126.com"
git config --list

export http_proxy=http://192.168.5.104:10809
export https_proxy=https://192.168.5.104:10809

git config --global http.proxy http://192.168.5.104:10809
git config --global https.proxy https://192.168.5.104:10809

############取消代理############
git config --global --unset http.proxy
git config --global --unset https.proxy

unset http_proxy
unset https_proxy

5.1 ERROR: Meson version is 0.61.2 but project requires >= 1.1¶

The Meson build system Version: 0.61.2 Source dir: /home/hywelstar/Develop/gstreamer Build dir: /home/hywelstar/Develop/gstreamer/builddir Build type: native build

meson.build:1:0: ERROR: Meson version is 0.61.2 but project requires >= 1.1

解决办法：

$ meson --version

其他可能报错 error: externally-managed-environment

解决：

pip3 install meson==1.3.1 --break-system-packages

meson 版本过低，强制安装meson 版本。
