如何在Ubuntu18.04 LTS上安装OBS (开放广播软件)而没有错误

Question

在没有依赖项或ffmpeg错误的情况下，为Ubuntu18.04LTS构建OBS有哪些步骤？

我最初在这里遵循了Ubuntu正式文档：https://obsproject.com/wiki/install-instructions#linux，如下所示：

$sudo apt-get install ffmpeg $sudo add-apt-repository ppa:obsproject/obs-studio $sudo apt-get update $sudo apt-get install obs-studio

这将导致软件包版本出现问题：

The following packages have unmet dependencies: obs-studio : Depends: libavcodec57 (>= 7:3.4.4) but 7:3.4.2-2 is to be installed or libavcodec-extra57 (>= 7:3.4.4) but it is not going to be installed Depends: libavdevice57 (>= 7:3.4.4) but 7:3.4.2-2 is to be installed Depends: libavformat57 (>= 7:3.4.4) but 7:3.4.2-2 is to be installed Depends: libavutil55 (>= 7:3.4.4) but 7:3.4.2-2 is to be installed Depends: libswresample2 (>= 7:3.4.4) but 7:3.4.2-2 is to be installed Depends: libswscale4 (>= 7:3.4.4) but 7:3.4.2-2 is to be installed E: Unable to correct problems, you have held broken packages.

从源头构建，用Git克隆：

git clone --recursive https://github.com/obsproject/obs-studio.git

...still给了我错误：

CMake Error at /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message): Could NOT find FFmpeg (missing: FFMPEG_AVCODEC_LIBRARIES FFMPEG_AVCODEC_INCLUDE_DIRS avcodec avdevice avutil avformat)

Answer 1

在运行cmake和make之前添加以下库：

$sudo apt install libavcodec-dev libavformat-dev libavdevice-dev (参考文献：如何从Launchpad下载和安装ffmpeg？)

接下来您需要：$sudo apt-get install libmbedtls-dev

Qt5Svg也是必需的：$sudo apt-get install libqt5svg5-dev
