MacTheRipper是一个非常简单的安装-只要拖动M acTheRipper的。药到您的应用程序文件夹。 ffmpegX is a bit more tricky (but certainly not hard) - just follow the instructions at ffmpegX是一个更棘手的（但肯定不是很难） -只需按照指示 http://ffmpegx.com/download.html carefully.仔细。

I’ve been looking all over to figure out how to do this.我一直在找都找出如何做到这一点。 I thought I was going to have to buy Conversion - Thanks!!!我想我必须要购买的转换-谢谢！
Ian,伊恩，
Glad to hear it helped很高兴听到它帮助
Has anyone else seen this problem?别人已经看到这个问题？
After clicking Encode, the encoding process finishes almost immediately, and apparently successfully, but no audio file is saved.在点击编码，编码过程完成后几乎立即，显然成功，但没有音频文件保存。 Clicking the info button shows this:按一下按钮，显示信息如下：

Any help/thoughts?任何帮助/想法？ Thanks!谢谢！
The process above works well for DVDs that have AC3 audio track.这个过程上述工程以及DVD的有AC3音频轨道。 I was wondering what to do about those DVDs that have PCM tracks instead.我不知道该怎么做那些有DVD的轨道不是的PCM 。 Mac The Ripper and osex will both rip the DVD audio to .PCM files, but I can’t find a way to go from .PCM files to .MP3.苹果的手和osex都将撕裂的DVD音频。的PCM文件，但我不能找到一种方法，从。的PCM文件。 MP3播放。 Any hints on that are much appreciated.任何暗示的高度赞赏。 I have two concert DVDs that I really want in my iPod and am having zero luck.我有两个音乐会的DVD ，我真的希望在我的iPod和10:00零运气。 Thanks!谢谢！
If you encounter where 0kb mp3 files are generated and get error “could not find input stream” , then try running the following from terminal:如果您遇到在0kb mp3文件的产生和得到的错误“无法找到输入流” ，然后尝试运行以下从终端：
/Applications/ffmpegX.app/Contents/Resources/ffmpeg -ab 256 -i in.ac3 out.mp3 /应用/ ffmpegX.app /目录/资源/ ffmpeg抗体256一in.ac3 out.mp3
You need to key in the correct file paths and names but it worked for me!你需要的关键在正确的文件路径和名称，但它为我！
Another tip solution that worked without using the console - just ensure you select the target format in ffmpegX to be AUDIO file to MP3 - the others are not working as Ross rightly mentions in the tutorial.另一端的解决方案，努力不使用控制台-只要确保您选择的目标格式f fmpegX将音频文件的M P3-其他人无法正常工作提到罗斯正确的教程。
Great guide.伟大指南。 However, I am having one problem by following these steps.不过，我有一个问题，按照下列步骤。
I extract a single AC3 stream with MTR, and test it with VLC player.提取一个单一的AC3流与地铁站，并测试它与可变长编码的球员。 It plays fine.它发挥的罚款。
However, after I encode the mp3 using ffmpegx the song shows up in the mp3 2 times (back to back)然而，在我的mp3编码使用ffmpegx这首歌出现在了MP3的2倍（背靠背）
(FYI I am running this on Leopard) （供参考，我运行这对豹）
Any Ideas?任何想法？
I take that back!我是否该回来了！
MTR is the one putting the song 2 times in the extracted AC3 file.地铁是一个把歌曲的2倍中提取的AC3文件。
I am using MTR 3我使用的地铁3
Any ideas?任何想法？
For those who had trouble using this method, here’s an alternative (I just used it with PCM audio):对于那些谁遇到了麻烦使用这种方法，在这里的另一种（我只是用它与PCM音频） ：
I was able to extract a chapter of a DVD using Handbrake, as an AVI with MP3 (you probably want a ridiculously high bitrate, as it will later be converted to AIFF, before being converted to whatever you want.) I was able to open and play the AVI with Quicktime Player (and the help of Flip4Mac to handle the AVI video encoding–which may not be necessary just to access the MP3 track–I already had it installed.) I was able to trim the combined audio and video to the starting and ending point desired using Quicktime Player, then export the trimmed portion of the audio to AIFF using Quicktime Player’s export function.我能提取一章的一个DVD使用手刹，作为一个带有MP3格式（你可能想要一个可笑的高码率，因为它稍后将转换为AIFF ，然后被转换成任何你想要的。 ）我能打开并发挥的AVI与Quicktime播放器（和帮助下， Flip4Mac处理的AVI视频编码，它可能没有必要仅仅获得了MP3跟踪我已经安装了它。 ）我能削减合并音频和视频在开始和结束点理想的使用Quicktime播放器，然后出口缩减的部分为AIFF音频使用Quicktime播放器的出口功能。 If you want another format, you can convert it with iTunes.如果你想要另一种格式，您可以转换与iTunes 。
Oh my gosh, I wish I had found this article two days ago.噢，我的天哪，我希望我已经找到本条前两天。 I wasted SOOO much time. SOOO我浪费了很多时间。
Thank you, thank you, THANK YOU!!!!谢谢你，谢谢你，谢谢你！ ！
Thanks for this step-by-step guide, couldn’t be any easier.感谢这一步一步指导，不能有任何方便。 On occasion though, the speed of my resulting mp3 is too fast, like doubled.有时不过，我的速度造成的MP3是太快了，就像增加了一倍。 Any suggestions on what I’m doing wrong or missing?任何建议，是我做错了或失踪？
@ Marco6 : ：
OK you have me stumped on that one.确定你有我难倒的一个。 I’ll google it and see if I can find anything, then get back to you.我将谷歌，看看我是否可以找到任何东西，然后回来给你。
Wow!哇！ Talk about complex for no reason.浅谈复杂，没有任何理由。
Use YADEX.使用YADEX 。 Its free and will do the same in a second!其自由和将采取同样在第二个！
How can I choose multiples chapters ((choose a start and end chapter)?我该如何选择倍数章（ （选择一个开始和结束章） ？
