为何我不论Ａ卡Ｎ卡播放视频画面都会撕裂

[supernan]

系统12.04，自动升级的源内最新内核，Ｎ卡装的源内闭源驱动，Ａ卡开源驱动；为何我不论Ａ卡Ｎ卡不管什么播放器播放视频画面都会撕裂？怎么办？求大神解答

[taohunter]

先提供以下信息：
1. 机器配置
2. 内核版本、A/N驱动使用的分别是哪个安装包
3. 用哪个版本的什么软件播放视频
4. 视频源是什么

A卡用的开源内核驱动
3.播放软件：源内mplayer2 (2.0-426-gc32b3ed-2ubuntu0.1)加外壳SMPLYAER，还有源内vlc (2.0.8-0ubuntu0.12.04.1)
4.任何视频文件都是这样的

[taohunter]

在terminal命令行用mplayer path/filename > mp_output.log的方式启动mplayer观看一个视频文件，运行一段时间出现你所说的画面撕裂现象时，就关闭mplayer。然后将mp_output.log传上来看一下，先看一下在N卡驱动下的情况吧。。。

为什么不升级到14.04 ?
A卡开源驱动已支持电源管理,硬解高清视频.

单看这个视频播放的相关log，除在log的中间部分出现的¨[matroska,webm @ 0xc97100]Unknown entry 0xF0¨这个错误外，并没有记录有其他的问题。以上那个错误应该是和mkvmerge相关的一个bug。

后续的问题和建议：
1. 确认一下¨视频撕裂¨这个问题是否在播放其他格式的视频时同样出现？例如mp4、flv、rmvb等。。。
2. 是否使用过其他的播放器播放同样的视频？例如vlc。如没有使用过，建议尝试用vlc再测试一次。在vlc里是可以设置一个参数避开mkvmerge的那个bug的，详见：
https://trac.bunkus.org/wiki/FAQ%3APlay ... kvmerge590
3. 如果以上的测试结果都一样的话，建议考虑采取以下方式再多做几次系统层面的变化：
a. N卡改用系统自带开源驱动或其他版本的闭源驱动
b. 使用更高版本的ubuntu及内核
理由： 我在3.5内核的12.04上测试了在N卡开源驱动下的mplayer/smplayer播放mkv视频，除内存与你一样，其他配置都比你差很多，但完全可以以稳定的帧率流畅播放。内核版本和N卡的闭源驱动版本多少是有些¨兼容性¨的关系的，既然你目前的驱动版本还是比较新的，建议配合更新版本的内核。。。

首先谢谢楼上！我换了14.04后播放效果好多了！还在测试
