Issues

Issues related to Homebridge, any camera plugins, or your config.json, should be raised on the corresponding project page or community support forums.

Issues strictly related to the compatibility or installation of the resulting binary may be raised here.

Plugin Dependency

This section is for Homebridge Plugin developers only, if you need to install ffmpeg see the instructions above.

You can optionally include this package as a dependency in your Homebridge camera plugins, by doing this the correct ffmpeg binary will automatically be downloaded to your user's server when they install your plugin.

npm install --save ffmpeg-for-homebridge

// .js
var pathToFfmpeg = require('ffmpeg-for-homebridge');

// .ts
import pathToFfmpeg from 'ffmpeg-for-homebridge';

// fallback to system ffmpeg (replace this with your own ffmpeg spawn command)
child_process.spawn(pathToFfmpeg || 'ffmpeg', []);

If ffmpeg is not supported on the user's platform, or this package failed to download the ffmpeg binary, the package will return undefined, you should check for this and and try and use ffmpeg from the user's PATH instead.

You will need to update your plugin's README installation command to include the --unsafe-perm flag. For example:

# example 
sudo npm install -g --unsafe-perm homebridge-fake-camera-plugin

FFMpeg是国外的一个开发小组开发的用来转换各种格式的多媒体的软件。目前他们的软件和介绍文档主要在http://www.sourceforge.net里。专区为：http://ffmpeg.sourceforge.net 在一般的视频处理里，往往会接触到很多处理视频格式的要求，比如把wmv转换成flv等等的。在.net的环境里，如果没有第三方的程序，一般可以处理的也就是WMV，WMA，WA
