ubuntu20.04环境下编译TBS系列DVB卡驱动模块安装到系统内核实现Tvheadend识别

一：编译环境配置

1：ubuntu下载安装：https://ubuntu.com/download/desktop

2：移除旧驱动：sudo apt autoremove

3：内核更新：sudo apt update

4：依赖库安装

sudo apt-get install build-essential sudo apt-get install checkinstall

sudo apt-get install dpkg-dev sudo apt-get install dh-make sudo apt-get install fakeroot

sudo apt-get install gnupg sudo apt-get install patchutils libproc-processtable-perl

5：安装内核头文件

sudo apt install build-essential linux-header-$(uname -r)

sudo apt install dkms build-essential linux-headers-$(uname -r)

二：获取源码

1：git clone https://github.com/crazycat69/linux_media latest #分支或指定commit

git clone https://github.com/tbsdtv/linux_media master #分支或指定commit

2：TBS官方本地下载：https://www.tbsdtv.com/download/index.html #推荐选择此源码

3：解压源码包至主目录：media_build-2025-04-28.tar.xz

4：进入源码目录

ubuntu@ubuntu-MacBookAir:~$ cd media_build-2025-04-28

ubuntu@ubuntu-MacBookAir:~/media_build-2025-04-28$ cd media_build

ubuntu@ubuntu-MacBookAir:~/media_build-2025-04-28/media_build$ sudo ./build

[sudo] ubuntu 的密码：输入设定的权限密码即可

截取编译过程开头日志如下：

make: 进入目录“/home/ubuntu/media_build-2025-04-28/media_build/linux”
wget https://github.com/tbsdtv/media_build/releases/download/last/linux-media.tar.bz2.md5 -O linux-media.tar.bz2.md5.tmp
此处获取临时源码树： https://github.com/tbsdtv/media_build/releases/download/last/linux-media.tar.bz2.md5

三：模块编译生成v4l目录下

make -C /lib/modules/5.15.0-139-generic/build M=/home/ubuntu/media_build-2025-04-28/media_build/v4l modules
