如何使用 docker 安装 guacenc？

Question

我用docker安装了guacamole和guacadmin，所以我也想用docker安装guacenc，但是没找到资料

其实我还没有找到其他安装guacenc的方法。如果有人知道，希望能得到答案。

非常感谢

Answer 1

如果guacamole和guacadmin可以安装在linux/windows/MacOS上那么就可以在docker里面运行.

Here 是 dockerhub 上 guacamole 的官方 docker 图片，你可以试试看。

同时检查 this。

更新：

要在 centos docker 映像中安装 guacenc，您需要安装必要的软件包 here。

引用thislink的说法。

The guacenc utility, provided by guacamole-server to translate screen recordings into video, depends on FFmpeg, and will only be built if at least the libavcodec, libavutil, and libswscale libraries provided by FFmpeg are installed.

The libavcodec, libavutil, and libswscale libraries provided by FFmpeg are used by guacenc to encode video streams when translating recordings of Guacamole sessions. Without FFmpeg, the guacenc utility will simply not be built.

您需要使用 yum install 安装这些包，以便可以构建和安装 guacenc 实用程序。

希望对您有所帮助。

此 dockerfile 仅供参考。谢谢

# This is a Dockerfile to build the docker image including guacenc service and ffmpeg utility.
# To reduce docker image size, utilize multi-stage build method and copy shared library file required while executing guacenc. 
# Copying shared library method is inspired by this thread "https://gist.github.com/bcardiff/85ae47e66ff0df35a78697508fcb49af"

# This Dockerfile is built off the https://github.com/apache/guacamole-server Dockerfile.
# In this repo, only Dockerfile provided. If you're about to build your own docker image, download whole project file from the link above.


# Encode existing session recordings to .m4v:
# $ docker exec -it guac_encoder guacenc -f /recordings/file-name-to-encode

# Convert .m4v to .mp4:
# $ docker exec -it guac_encoder ffmpeg -i /recordings/file-name-to-convert.m4v /records/file-name.mp4
