我的iPad應用程序使用戶能夠觀看幾百部視頻。目前iPad應用程序將它們指向MP4文件。不過，我想將它們指向QuickTime參考電影。 （如果用戶通過3G與WiFi連接，則允許該應用發送較低比特率的視頻版本。）iOS自動編碼視頻（以及創建參考電影）
現在，我在QuickTime中創建各種版本以及參考文件，方法是轉到文件 - >導出到Web。但是，這個過程（1）只允許我一次完成一個文件，並且（2）生成大量無用的東西，比如HTML和JavaScript。
我該如何自動化過程？有沒有人知道現有的腳本/工具來完成這項工作？我相信其他開發者之前必須這樣做。
我寫的（和其他的東西拼湊起來在網絡上）這個的AppleScript做的工作：
--property exportFolder : (path to documents folder as Unicode text) & "Your Folder:"
property QTExportPath : (path to movies folder from user domain)
property completedFolderName : "completion" -- this folder must already exist
property referenceFiles : {}
property encodeCount : 0
on run
choose folder with prompt "Choose folder with video files:" -- with multiple selections allowed
open (result)
end run
on open droppedItems
tell application "Finder"
set allFiles to every file of entire contents of droppedItems as alias list
end tell
-- Error checking
repeat with testFile in allFiles
set myChars to characters of basename(testFile)
if count_matches(myChars, ".") > 1 then
display dialog "ERROR: The file " & basename(testFile) & " has too many periods."
return
end if
end repeat
-- Made it past error checking, let's get started
tell application "QuickTime Player"
activate
close every window
end tell
repeat with thisItem in allFiles
tell application "QuickTime Player"
close every window
open thisItem as alias
end tell
activate application "QuickTime Player"
tell application "System Events"
tell process "QuickTime Player"
keystroke "E" using command down

set fileBaseName to basename(thisItem)
set lengthWithoutExtension to (count of fileBaseName) - (count of fileExt) - 1

set end of referenceFiles to fileBaseNameWithoutExtension
repeat until startedExporting(fileBaseNameWithoutExtension)
-- wait for this file to start exporting before beginning another

它假定：
設置您在QuickTime想要的任何出口設置將其導出一次一個。如果要同時轉換多個文件，請修改startedExporting方法以僅檢查文件夾而不是.mov文件（該.mov文件是要生成的最後一個文件）。
