event.duration

概述

当用户使用 media.captureVideo() 或 media.selectVideo() 选择或录制视频后，completion 事件被派发时，此属性表示视频的长度（以秒为单位）。

示例

-- Video completion listener
local onVideoComplete = function( event )
    print( "video session ended" )
end

-- Capture completion listener
local function onComplete( event )
    if event.completed then
        media.playVideo( event.url, media.RemoteSource, true, onVideoComplete )
        print( event.duration )
        print( event.fileSize )
    end
end

if media.hasSource( media.Camera ) then
    media.captureVideo( { listener=onComplete } )
else
    native.showAlert( "Corona", "This device does not have a camera.", { "OK" } )
end
