c#制作视频音频歌词相关技术代码记录

开发类似千千静听或者KMplayer等音频视频播放器播放字幕或者歌词的技术

从两方面着手,一是时间轴,二是帧(对于视频)。

方法一的实现比较简单,只需要内置一个定时器,在媒体播放时开始计时,然后读指定的脚本即可。

重装Windows后修复引导ubuntu

重装了windows后ubuntu就不能自动引导了,网上有很多方法,这里只说两种简单的

win xp:

  1. 复制wubildr.mbr,wubildr到C盘(这两个文件在安装Ubuntu磁盘下的winboot文件夹中)

  2. 然后打开磁盘下的boot.ini手动添加ubuntu选项

win7:

1.使用grub(方法网上有),但前提是使用硬盘安装而非wubi安装

Win7安装vs2010

安装VS2010到内牛满面

开始在win7 64位旗舰版下遇到错误无法安装vs2010,网上查找说与office07冲突……卸载后还是无法安装。

随后换成win7 32位,安装Framework4成功,可接下来遇到Object model失败,查了N久,无解,网上有人提出修改注册表RightOUT什么的,我是没见有谁用那个成功。偶然看到某些评论说是win7版本问题,原因不知。便更换了Lenovo的OEM版,重装vs2010。

果然,成功安装了。所以问题归结到操作系统上来。

自己做了实验:(总共重装系统9次)
