環(huán)境準(zhǔn)備
ubuntu發(fā)行版22.04，該發(fā)行版內(nèi)置Gstreamer1.20.1，gstreamer源碼最新版本為1.20.3，差距不大
下載gstreamer源碼
下載gstreamer源碼
安裝git
sudo apt install -y git
fuqiang@fuqiang-VivoBook:~/Workspace/gstreamer$ git --version
git version 2.34.1下載gstreamer
git clone https://gitlab.freedesktop.org/gstreamer/gstreamer.git
git checkout --track -b 1.20 origin/1.20 --->1.20是目前最新版本的穩(wěn)定分支，最新的小版本號為1.20.3準(zhǔn)備編譯環(huán)境
安裝meson
gstreamer1.60以后（不包含1.60），使用meson+ninja來構(gòu)建
sudo apt install -y meson
fuqiang@fuqiang-VivoBook:~/Workspace/gstreamer$ meson --version
0.61.2安裝glib
gstreamer是基于glib-gobject來實現(xiàn)的
sudo apt install -y libglib2.0-dev安裝libsoup
sudo apt install -y libsoup2.4-dev安裝libunwind
1.下載包，http://download.savannah.nongnu.org/releases/libunwind/
2. ./configure
3.make
4.sudo make install安裝libdw
sudo apt install -y libdw-dev安裝g-ir-scanner
系統(tǒng)中搜索g-ir-scanner，然后將其copy到/usr/lib/下，給予執(zhí)行權(quán)限
安裝gobject-introspection-1.0
sudo apt-get install -y libgirepository1.0-dev安裝gtk+-3.0
sudo apt-get install -y libgtk-3-dev安裝hotdoc
sudo apt-get install -y libjson-glib-devsudo apt install -y cmake python3-pip
sudo pip3 install hotdoc安裝xgettext
系統(tǒng)中搜索xgettext，復(fù)制到/usr/bin/下，并給予執(zhí)行權(quán)限
安裝alsa
sudo apt-get install -y libasound2-dev安裝cdda_paranoia
sudo apt install -y cdparanoia還不行將cdparanoia先注釋掉
安裝libvisual-0.4
sudo apt install libvisual-0.4-dev安裝xv
打開終端輸入 sudo snap install xv --edge，如果不能正常安裝則按照提示輸入 sudo snap install xv --edge --devmode即可安裝成功
安裝SDL2
sudo apt-get install -y libsdl2-2.0 libsdl2-dev libsdl2-mixer-dev libsdl2-image-dev libsdl2-ttf-dev libsdl2-gfx-dev安裝qt5
sudo apt-get install -y clang qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools qtcreator
sudo apt-get install -y qt5*安裝bz2
sudo apt install -y libbz2-dev安裝nasm/yasm
sudo apt install -y nasm yasm安裝gettext
sudo apt-get install -y gettext編譯安裝
創(chuàng)建out目錄
cd gstreamer
mkdir out編譯
meson out
cd out
ninja
sudo ninja install帶參數(shù)編譯示例
meson --reconfigure -Dauto_features=enabled -Dgst-plugins-base:opus=disabled -Dgst-plugins-base:ogg=disabled out異常處理

The Meson build system

Build dir: /home/fuqiang/workspace/gstreamer/out
Build type: native build
meson.build:81:15: ERROR: lexer
['gstreamer', {'build-hotdoc': true}],解決方案：更新meson版本，ubuntu18.04會出現(xiàn)這個問題，原因是其meson版本過低，使用pip3來安裝meson
sudo pip3 install meson如果版本還是低的話，可能/usr/bin有原始的meson，/usr/local/bin中是新安裝的meson，將/usr/local/bin下面的copy到/usr/bin下面即可文章來源：http://www.zghlxwxcb.cn/news/detail-449598.html
