是否可以使用 jsfl 从 flash 库中导出声音文件？

Question

我发现这个脚本似乎可以满足我的需要，但是，当我尝试导出文件时，我得到“文件名：假”作为输出。有什么想法吗？

花了我一点时间，但我发现了你的问题。问题在于您的声音文件的这个小属性：soundItem.originalCompressionType。 You can find some detail for the issue here。您的代码中发生的情况是，它将尝试将声音文件导出为存储在库中的类型。即 filename.mp3 保存为 .mp3 文件，filename.wav 保存为 .wav 文件。如果soundItem.originalCompressionType 等于“RAW”，则无法将声音文件另存为 .mp3 文件，因此会输出“filename: false”。您必须将文件另存为 .wav 文件。在定义 imageFileURL 时，我稍微修改了代码。

// Result of attempts to export will go to the output panel,
// so clear that first fl.outputPanel.clear();

// If bitmaps/audio in the library have been selected, export only
// those. Otherwise, export all bitmaps/audio in the library.

var lib;
if (fl.getDocumentDOM().library.getSelectedItems().length > 0) {
    lib = fl.getDocumentDOM().library.getSelectedItems(); 
} else { lib = fl.getDocumentDOM().library.items; } 

// Get destination directory for files 
var imageFileURLBase = fl.browseForFolderURL("Select a folder."); 
var imageFileURL; 

var totalItems = lib.length;
// Iterate through items and save bitmaps and 
// audio files to the selected directory.
for (var i = 0; i < totalItems; i++) 
{
    var libItem = lib[i];
    if (libItem.itemType == "bitmap" || libItem.itemType == "sound") 
    {
        // Check the audio files original Compression Type if "RAW" export only as a .wav file
        // Any other compression type then export as the libItem's name defines.
        if(libItem.itemType == "sound" && libItem.originalCompressionType == "RAW")
        {
            wavName = libItem.name.split('.')[0]+'.wav';
            imageFileURL = imageFileURLBase + "/" + wavName;
        } else {
            imageFileURL = imageFileURLBase + "/" + libItem.name;
        }
        var success = libItem.exportToFile(imageFileURL);
        fl.trace(imageFileURL + ": " + success);
    }
}
