根据 VideoLAN 的说法，为了避免得到一个非常基础版本的 VLC，需要设置某些特定的 USE 标志[2]。其中许多可能已经过时，或由所选的 profile 设定。
多媒体在线流
VLC provides users with the option to stream multimedia objects (YouTube, Vimeo, music, and more). To enable this functionality, simply enable the lua USE flag. If app-portage/gentoolkit is installed (it is a highly recommended package to have), simply issue:
root #euse -E lua -p media-video/vlcAfter proper configuration and installation, streams can be opened via Media --> Open Network Stream.... Enter URLs to popular multimedia websites, such as YouTube or other websites.
Webm 支持
Webm is a popular video format. To have it work the vorbis, vpx, and matroska USE flags must be enabled.
Emerge
在设置了初始安装所需的 USE 标志后，安装 VLC：
root #emerge --ask media-video/vlcUsage
Alternate interfaces
VLC provides multiple interfaces in addition to the default GUI interface. There is an ncurses-based interface, and a HTTP interface that can be used for streaming or as a remote control. The VLC wiki has a section dedicated to explaining the alternative interfaces.
HTTP
When connecting to the HTTP interface, make sure a password is set.
Leave the user name field blank when entering credentials on the web page.
Hotkeys
VLC supports a host of hotkeys[3] for more efficient operation. There is an article on the VLC wiki detailing all available hotkeys for the Qt interface.
