这似乎应该很简单，但我在这里空手而归。我正在尝试制作一个简单的VLC脚本，检查“随机”按钮是否打开，如果它跳转到随机文件，而不是在时间= 0开始，它将随机开始。
到目前为止，它正在寻找我喜欢它应该是一个播放列表脚本，我可以从播放列表对象获得持续时间，但在this documentation page或Google，我似乎没有找到任何方式跳到一个特定的时间内Lua脚本。有没有人有更多的经验来控制VLC播放与Lua？
解决方法
实际上，文件确实说你可以做到这一点，尽管不是这么多话。以下是播放列表解析器的界面说明：
VLC Lua playlist modules should define two functions:
* probe(): returns true if we want to handle the playlist in this script
* parse(): read the incoming data and return playlist item(s)
Playlist items use the same format as that expected in the
playlist.add() function (see general lua/README.txt)
如果你遵循playlist.add()的描述，它说这些项目有一个很大的可以提供的字段列表。有很多选择(.name，.title，.artist等)，但唯一需要的一个似乎是.path …这是“项目的完整路径/ URL”。
没有明确提到在哪里寻找，但您可以选择提供的参数之一是.options，被称为“VLC选项列表”，以全屏为例，如果平行到全屏幕工作，可以其他命令行选项如 – 启动时间和停止时间工作？
在我的系统上，他们做，这里是脚本！
-- randomseek.lua
--
-- A compiled version of this file (.luac) should be put into the proper VLC
-- playlist parsers directory for your system type. See:
--
-- http://wiki.videolan.org/Documentation:Play_HowTo/Building_Lua_Playlist_Scripts
--
-- The file format is extremely simple and is merely alternating lines of
-- filenames and durations,such as if you had a file "example.randomseek"
-- it might contain:
--
-- foo.mp4
-- 3:04
-- bar.mov
-- 10:20
--
-- It simply will seek to a random location in the file and play a random
-- amount of the remaining time in the clip.
function probe()
-- seed the random number since other VLC lua plugins don't seem to
math.randomseed(os.time())
-- tell VLC we will handle anything ending in ".randomseek"
return string.match(vlc.path,".randomseek$")
end
function parse()
-- VLC expects us to return a list of items,each item itself a list
-- of properties
playlist = {}
-- I'll assume a well formed input file but obvIoUsly you should do
-- error checking if writing something real
while true do
playlist_item = {}
line = vlc.readline()
if line == nil then
break --error handling goes here
end
playlist_item.path = line
line = vlc.readline()
if line == nil then
break --error handling goes here
end
for _min,_sec in string.gmatch( line,"(%d*):(%d*)" )
do
duration = 60 * _min + _sec
end
-- math.random with integer argument returns an integer between
-- one and the number passed in inclusive,VLC uses zero based times
start_time = math.random(duration) - 1
stop_time = math.random(start_time,duration - 1)
-- give the viewer a hint of how long the clip will take
playlist_item.duration = stop_time - start_time
-- a playlist item has another list inside of it of options
playlist_item.options = {}
table.insert(playlist_item.options,"start-time="..tostring(start_time))
table.insert(playlist_item.options,"stop-time="..tostring(stop_time))
table.insert(playlist_item.options,"fullscreen")
-- add the item to the playlist
table.insert( playlist,playlist_item )
end
return playlist
end
