Joost故障答疑之运行篇

今天登录Joost明显时间变长了，而节目却流畅了N多。谢谢诸位的安装和使用，让节目运行得更加顺畅。已经有部分网友留言，谈到了他们的经验和认知，因此我把它们贴出来和大家共享一下：

pearz：数据是使用H.264编码压缩的，画质远远超过rmvb。根据官方提供的数据，一小时的下载量为320M左右，在网络通畅的情况下，1Mb的宽带即可满足要求。软件最多会使用2G作为数据交换空间。

进化中：装在非系统盘是没用的,joost的文件保存在Documents and Settings\用户名\Application Data\joost下,也就是在系统盘下,即使装在非系统盘也是一样的.并且, joost下载完的文件是不会自己删除的.

此外，我也想告诉大家：Joost支持MAC和Linux操作系统。但是对于视窗系统，只支持XP sp2以上版本，包括Vista，但是不支持Win2000。从留言里看到有很多朋友为了安装Joost，居然放弃了自己的Win2000，重新安装XP。对此，我只能说：Dude, you are fucking crazy！

我昨天一度动了汉化Joost客户端程序的念头，但是没有合适的工具对对付JAR文件，也没有合法的数字签名。所以，这里我把需要汉化的文件名称和地址提交出来，希望有所帮助。不过，因为是Beta版，所以现在就动手翻译可能为时过早，因为新版本一旦出现，可能会立即覆盖这些文件。同时，也提醒国内的各大字幕组，Joost可能会提供节目的多语言版字幕翻译，你们的舞台又扩大了。

既然已经有如此之多的人在使用Joost，所以我就把Joost官网上的故障答疑翻译了一部分出来，希望对大家有所帮助（为了防止我翻译中的错误，因此提供双语版本）：

The client crashes and I get a message saying "software conflict detected"

We're working hard to improve Joost's interaction with other applications, especially with anti-virus and firewall software. We are aware of some issues and we're working to solve them for an upcoming release, but unfortunately there's no quick fix at the moment. Currently, your best bet is to disable any software you suspect interferes with Joost when you want to watch TV.

客户端程序崩溃了，我得到一条提示说：software conflict detected （侦测到软件冲突）

回答：我们正努力提高Joost客户端程序和其他应用程序的交互性，特别是和杀毒软件与防火墙的交互性。我们已经知道有类似问题的存在，而且我们也正努力在新版本中解决这些问题。可是，现在我们还不能提供快速修复的方法。就目前而言，当你用Joost看网络电视节目的时候，最好的办法是禁用任何你怀疑会影响到Joost客户端程序运行的应用程序。

I can't see any video! What do I do?

There are two common reasons why you may not see video - either 1) because UDP access is restricted by your broadband provider, or 2) because your firewall or router is blocking traffic to the ports used by the Joost software to stream video.

1) because UDP access is restricted by your broadband provider, or 2) because your firewall or router is blocking traffic to the ports used by the Joost software to stream video.

UDP access: Joost relies on UDP (User Datagram Protocol) for its video streaming and TCP (Transmission Control Protocol) for its peer-to-peer management. Both are internet standard protocols. It uses UDP instead of TCP because it gives users a faster, more robust experience. Using UDP, the application is able to more quickly switch channels and stream video with fewer interruptions and less stutter.

A few broadband providers restrict their UDP traffic more than they do their TCP traffic because they feel it makes them more secure, and UDP is not usually critical. A client may therefore be able to connect and start up because that depends on TCP, but then fail as soon as a video is tried because of the need for UDP. If you repeatedly experience problems connecting, contact your provider and ask them about enabling UDP access.

Opening ports required by Joost: If you know that your ISP allows you to use UDP but still can't see any video, you'll need to check that your firewall or router is configured to allow access by Joost application. In particular, make sure that the following are enabled:

* TCP access, outbound, to ports 80, 443 and 5223.
* UDP access, outbound, to port 33333.
* If you have a public IP address and UDP inbound on port 33333 is unfiltered, the client may use UDP on port 33333 inbound.
* If you want to chat from within Joost, you'll also need to enable inbound TCP access to port 5223.

Check also that your network has DNS servers configured - Joost client makes regular DNS requests like any other application.

我不能看到任何视频节目，我应该怎么办？

回答：有两种最常见的原因导致你无法看到视频节目，要么是1）你的宽带服务商限制了UDP（用户数据报协议）的访问；要么就是2）你的防火墙或者路由器禁用了Joost软件流媒体所需要的使用的端口。

UDP 访问：Joost依赖UDP（用户数据报协议）来得到视频流，同时使用TCP（传输控制协议）来进行点对点传输控制。它们两个都是标准的互联网协议。之所以用UDP协议代替TCP协议是因为UDP协议能带给用户更快更有力的使用体验。使用UDP协议的应用软件能更快地在频道和流媒体节目之间切换，减少中断和断断续续的情况。

出于安全上的考虑，和对TCP相比，少数宽带服务商对UDP做了更多的限制。但是，通常情况下UDP并不危险。因此，应用程序在一开始能够运行和开始，因为这时候它用的是TCP协议。但是，只要它开始试着下载视频，那么就会立即失败。因为这时候它用的是UDP协议。如果你在连接的时候重复发生类似的问题，请你联系你的宽带服务商，要求他们允许UDP访问。

Joost 需要开放的端口：如果你确信你的网络服务商（ISP）允许你使用USP协议，但是你依然看不到任何视频，那么你就需要检查一下你的防火墙或者路由器。看看它们是否设置了允许JOOST客户端程序进行访问。特别注意的是，你要确认以下端口已经打开：

* TCP 访问,，对外端口号： 80, 443 和5223.
* UDP 访问，对外端口号： 33333.
* 如果你有一个公有IP地址，而且UDP对内端口33333没有被过滤，那么Joost客户端程序可以使用UDP对内端口33333。
*如果你向使用Joost的聊天频道，那么你还需要打开TCP服务对内端口5223。

还需要检查你的网络DNS服务器配置，Joost客户端程序和其他应用程序一样，需要做常规DNS解析申请。

When I start Joost it immediately says "you got disconnected from the Venice network".

This is probably due to your firewall settings. You need to configure it to open the ports used by Joost. See I can't see any video! What do I do? for more details.

当我开始运行Joost以后立即看到了“你从威尼斯网络断开了连接“（you got disconnected from the Venice network）。

回答：这可能是因为你的防火墙设置而造成的。你需要设置你的防火墙，打开Joost需要使用的端口。参见“我不能看到任何视频节目，我应该怎么办？”问答以获得更多详细资料。

I get a "disk full" error

When the client runs, it creates a cache on your hard drive that on occasions can become relatively large in size (up to 2GB). However, it shouldn't normally fill up your disk, unless it was almost full to start with. We are aware that there is a Joost bug which shows up Disk Full errors when the disk is not full and asks for more info about your computer. If this happens, check if your disk is really full and if it is, try to free up some disk space and if the problem persists, check the support forums.

我遇到了“硬盘已满”（disk full）错误。

回答：当客户端程序运行以后，它会在你的硬盘上形成一个缓存文件。有的时候，它的大小可以达到2G。可是，除非你的硬盘早就快满了，否则正常情况下它不应该占满你的硬盘空间。我们知道有一个Joost的漏洞，当你的硬盘还没有全满，但是应用程序会报告硬盘已满错误，而且向你询问更多你电脑的信息。如果发生这样的情况，请检查你的硬盘空间是否真的满了。如果的确如此，那么请试着释放部分硬盘空间。如果问题依然存在，请访问我们的技术支持论坛。

Does Joost run on Windows Vista?

Yes. You will need an administrator password to install Joost, but running it as a normal user works.

Joost能够在Windows Vista下运行吗？

回答：可以，你需要使用管理员密码才能安装Joost，但是使用普通用户名就能够运行。

Where should I report bugs?

It's much better to report bugs from within the Joost application if possible, because it will automatically send us technical and version information that's very useful for solving problems. See below for details of how to do this.

我应该向哪儿报告错误？

回答：如果可能的话，最好使用Joost客户端程序内部的报告功能报告错误。因为这样的话，客户端程序将能自动报告我们关于技术上和版本上的信息，这将对我们解决问题非常有帮助。请参见以下如何提交错误的详细信息。

How do I report a bug?

There's a link in the client to the bug report page in the menu - just press F1 and it's at the bottom.

If for some reason the application won't run at all, you can use the bug report form on the website directly.

If you are using the Windows client, please send us a dxdiag summary - see the next question for details of this. If you have a directory named 'The Venice Project (Baaima N.V.)' in the %APPDATA% directory, please include the file anthill.log in your email. Also, details of any anti-virus or firewall software you use are very helpful.

我应该怎样报告错误？

回答：在客户端程序的菜单里有一个链接指向报告错误的页面---只需按下F1键，它就会出现在屏幕底端。

如果因为某些原因造成客户端程序根本不能运行，你可以直接使用我们官方网站上的错误报告论坛。

如果你使用WINDOWS客户端程度，请向我们发送dxdiag程序摘要。请在下一个问题里阅读相关详细信息。如果你的有一个叫 'The Venice Project (Baaima N.V.)'的子目录在在%APPDATA% directory目录下，请把其中的anthill.log 文件一并发送给我们。此外，你所使用的所有防火墙和杀毒软件的详细信息对我们也大有裨益。
