還有一個問題需要求助一下@@,
在選1撥放320X240影片時, 相當正常,
但是選擇2撥放640X480的撥放時, 會出現
vo_bvdd: couldn't open /dev/bvdd, reason No such file or directory.

我檢查/dev下, 確實沒有bvdd的檔案或資料夾, 是少裝了什麼嗎?
我有裝教學裡的
mplayer_1.0pre8_armv5tel.ipk
mplayer-bvdd-iwmmxt_1.1.5-1_armv5tel.ipk,

而mplayer-bvdd-iwmmxt_1.1.5-1_armv5tel.ipk換成
mplayer-bvdd-iwmmxt_1.2.0-1_armv5tel.ipk也是出現一樣的訊息

 Post subject: BVDD的介绍
BVDD只用于pxa270以上的CPU，目前就是C1000, C3XXX机型，kernel支持的，楼上是用7500C的吧？

Bvdd Video Driver
From OESF
Jump to: navigation, search

This is information on the bvdd driver that I've gathered from the net. I'm not an expert on the subject, so right now this document is subject to errors Contents
1 What is bvdd?
2 How do I get it?
3 How do I use it?
4 Known Issues
5 Where to find more

[edit] What is bvdd?

bvdd seems to be an abbreviation for "Bulverde", the Intel code name for the XScale PXA27x CPUs that the C1000/C3x00 models are based on. This may indicate that this capability is built into the CPU rather than a Zaurus-specific hardware feature.

bvdd is a video driver that offers enhanced video performance on the C1000/C3000/C3100 models. It does not seem to be present in Sharp roms, so it appears to be a user contributed feature. It looks like it may have originated in the Tetsu kernels.

Several descriptions describe it as overlay, so perhaps it works similarly to the hardware overlays found in desktop cards which are often used for video and DVD playback.
[edit] How do I get it?

Bvdd is a kernel module or built into the kernel itself. The easiest way to get it is to install the Cacko Rom for the C1000/C3x00 series.

The package bvdd_0.4.0-1_arm.ipk might add bvdd to the stock Zaurus kernel.
[edit] How do I use it?

Applications need to take advantage of it. Currently these applications/libraries support bvdd: App/lib Package To Install Notes
mplayer mplayer-bvdd_1.1.5-1_arm.ipk use -vo bvdd or kino2 frontend
libSDL libsdl-1.2.5-bvdd-07-2_arm.ipk Extends bvdd support to games and emulators compiled against SDL ++

I do not know if using the bvdd version of SDL automatically improves performance of SDL apps, or if they need to take special steps to take advantage of it -- Uth
[edit] Known Issues

There is a bug in libsdl-1.2.5-bvdd-07-2_arm.ipk that prevents the FM Towns versions of Zak McKracken, LOOM and Indiana Jones and the Last Crusade from running in ScummVM. All other supported titles are not affected by this bug. If you wish to run these FM Towns games you can not use this version of libsdl and must use a different version (for example: libsdl-1.2.5-slzaurus20041025-j.ipk).

Tested on a C1000 with Cacko 1.23, ScummVM 0.8.2 and ScummVM 0.7.0.

难怪，bvdd在2.6以上核心用的是另外的功能代替

the bvdd is a 2.4 kernel enhancement as in module specific for the C3x00/C1000 hardware only. the equivalent in feature on the 2.6 kernel is the pxa overlay feature which currently is experimental and mplayer and other apps or libs such as sdl that want the specific optimization need to be compiled with support for that...

 Post subject: 请您一定要帮帮我，我将感激不尽，永远不忘您的大恩大德
我去年买了一部大陆行货的SL-7500C掌上电脑，是夏普和CECT合作推出的。我一直用的原厂ORM，而且一

直用得好好的，直到前天在网上看到这个论坛上介绍的那个基于PDAX系统的影音播放器mplayer-bvd，说

是除rm格式外无所不能，号称全能播放器，我对软件方面尤其是掌上电脑这块可以说是完全的外行，我

买这个机器完全是因为我喜欢它的外形，就买了它，而我用得最多的也就是一些最基本最简单的功能，

如看电影，听音乐，看电子书。因为对软件太不懂了，所以当时就以为这个播放器一定也可以用在我的

7500上（现在的系统上），于是就下载了安装到机器上，谁知安装上去没显示，更别提能放电影了，于

是我就把它给卸载了，想想还是继续用我的超级播放器吧。可哪里知道，原来可以用的超级播放器现在

也用不成了，我好后悔啊，想想不能用了留着它也没有用处，反而占地方，于是把它也卸载了。我想在

网上找一下也许还可以下得到这个播放器，但毫无结果，不过最后在一个网页上看到7500C金蜂原厂的系

统恢复包，这个东西在我买机器时随机附送的软件光盘里有，而且超级播放器就在这里面，我高兴死了

，以为找到了救星，于是我以最快的速度把它下下来，安装在我的 SD卡上的根目录上（按说明操作的）

，然后在机器上进行恢复，可恢复没几秒钟机器就提示恢复失败，然后开机怎么也进不了系统了，我好

伤心啊，不下这个东西还可以用的，顶多就是不看电影了，看看书就完了，可现在，弄得完全不能用了

，我尝试着在网上找解决办法，OK方式试过了，不行，DM方式我不知道怎么开机，只看到论坛上介绍用

DM模式装PDAX系统，我突发奇想不如就在DM模式下装PDAX系统，也许装上了再运行恢复，可以回到原厂

系统，这样想，我就接照教程上说的一步步操作，下系统，然后安装，但开机时还是不能进入系统，虽

然开机界面换成了PDAX系统界面，但和开始的情况一样，一直在启动，但就是进不了系统，我想可能是

安那个网上下载的系统恢复包进行恢复，把系统的某个运行程序破坏了，倒致无法正常启动无法正常进

入系统，我后来安装了新的PDAX系统，但因为原来的运行程序被破坏了所以还是无法安装完成，无法进

入系统，我现在记得刚买机器时进行系统恢复包的恢复操作时也有过恢复失败的情况，经过卖家（金蜂

厂家专卖）的一步步口授，格式化机器，然后再运行恢复操作就可以恢复成功，然后正常开机，进入系

统。我想现在的情况和那时差不多，所不同的是我后来又把它刷成PDAX系统了，虽然没有刷成功，但界

面已经换成了PDAX系统的界面了。我不知道现在用格式化机器的方法有没有用？我不敢试，怕万一操作

不对，把机器弄坏就麻烦了，而且因为我现在在外地，没有带电源线（说明上说进行格式化操作时一定

要接上电源）无法进行格式化操作，我想请教您，我现在的这个情况正确的解决办法是怎样的？我试过

OK方式，不行，DM方式好象没有开机的，只有升级新系统的，请一定要帮帮我，我都快急死了，我好怕

机器坏了不能用了，那我就损失惨重了，而且如果是这样的话我想我会疯掉的，我会后悔死的，好好的

非要安什么鬼软件，现在好了，几千块钱的东西搞得不能用了，我想我会受不了这个刺激的。请帮帮我

吧，我会感激不尽的。请给我发信息13107536011，因为我不常上网（工作的关系），而且论坛的贴子太

多了，想找回复太不方便了，所以请给我回短信吧，真的感激不尽。谢谢了

zthdav你應該很緊張吧, 我想機器應該是不太會壞掉, 有可能是你下載的ROM不完整, 導致你恢復失敗或開機失敗, 你可以看一下這個討論串http://z.osall.com/viewtopic.php?t=1659, 裡面也有人遇到跟你類似的問題 , 你的問題也比較適合這個討論串, 希望你能夠解決

原來bvdd在2.6以上核心用的是另外的功能代替, 難怪我不能用了,
看來有點無解了, 除非我刷1.1.0.beta3, 或是有人為2.6 kernel 編一版mplayer, 有點遺憾, 最近幾乎想用的東西都爬文一個一個建置起來了, 差這一個,哈

謝謝ccpaging為我解答
