我想使用Java使用Quicktime进行录制，但是当我尝试输入文件夹和文件时出现了一些问题。我虽然这可能是一个时间问题，所以延迟但仍然会发生。开始录制的代码是：
public static void startQTrecord(){
//Activate QT
try{
String[] go = { "osascript", "-e", "tell application \"QuickTime Player\" to activate" };
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
//Start new recording
try{
String[] go = { "osascript", "-e", "tell application \"QuickTime Player\" to start new movie recording" };
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
停止和保存的代码是：
public static void closeQT(){
//Go to QT
try {
String[] go = {"osascript", "-e", "tell application \"QuickTime Player\" to activate"};
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
//Stop the recording
try {
String[] go = {"osascript", "-e", "tell application \"QuickTime Player\" to stop document \"movie recording\""};
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
//Save
try {
sleep(100);
String[] go = {"osascript", "-e", "tell application \"System Events\" to keystroke \"s\" using {command down}", "-e", "delay 1"};
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
//Enter the save directory
try {
sleep(100);
String[] go = {"osascript", "-e", "tell application \"System Events\" to keystroke \"G\" using {command down, shift down}", "-e", "delay 1"};
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
try {
sleep(100);
String gofolder = "tell application \"System Events\" to keystroke \"" + folder + "\"";
String[] go = {"osascript", "-e", gofolder, "-e", "delay 1", "-e", "tell application \"System Events\" to keystroke return", "-e", "delay 1"};
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
try {
sleep(100);
String[] go = {"osascript", "-e", "tell application \"System Events\" to keystroke\""+file+"\"", "-e", "tell application \"System Events\" to keystroke return", "-e", "delay 1"};
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
/////////////////////////////////////////////
//Wait for save then quit
boolean keepWaiting = true;
while(keepWaiting){
try{
Runtime rt = Runtime.getRuntime();
String[] commands = {"osascript", "-e", "delay 5", "-e", "tell application \"QuickTime Player\" to quit"};
Process proc = rt.exec(commands);
proc.waitFor();
BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream()));
String s = null;
// read any errors from the attempted command
if(stdError.readLine() == null){keepWaiting = false;}
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
}
}
有时它工作正常，但有时它会到达文件夹窗口，而不是粘贴正确的文本。
关于为什么这不起作用或者有更好的方法的任何想法？
谢谢！

最好使用AppleScript的保存命令，而不是使用按键命令
public static void closeQT(){
//Pause the recording, save and quit
try {
String[] go = {"osascript", "-e", "set tFile to \""+fullPosixPathOfFile+"\" as posix file", "-e", "do shell script \"touch \" & quoted form of posix path of tFile", "-e", "tell application \"QuickTime Player\"", "-e", "pause document 1", "-e", "save document 1 in tFile", "-e", "stop document 1", "-e", "close document 1 saving no", "-e", "quit", "-e", "end tell"};
Process process = Runtime.getRuntime().exec(go);
process.waitFor();
} catch (IOException ex) {
System.out.println(ex.toString());
} catch (InterruptedException ex) {
System.out.println(ex.toString());
}
}
将要保存影片的文件路径放在fullPosixPathOfFile变量
这是一个有效的AppleScript示例
set tFile to (path to desktop folder as string) & "MyMovie.mov" -- save the movie to the desktop
do shell script "touch " & quoted form of POSIX path of tFile -- "QuickTime Player" need an existing file (otherwise permissions issue), so the touch command create an empty file
tell application "QuickTime Player"
launch
set newMovieRec to new movie recording
tell newMovieRec
start
delay 10 -- duration in seconds of this new movie
pause
save in (file tFile) -- The term "file" is necessary when the type of the path is HFS (path with colon character --> "diskName:folder1:subFolder2:myMovie.mov")
--save in tFile -- use this line when the tFile variable contains a posix file (a posix path converted to a posix file)
stop
close saving no
end tell
quit
end tell
检查 Quicktime 的版本：
tell application "QuickTime Player"
set v to version
considering numeric strings
set newVersion to v > "7.6.6" -- change it to the old version which not work
end considering
if newVersion then
-- code to save
else
-- code to save as
end if
end tell
