飞天的梦想

还记得童年时候的动画吗？ 奔奔是我当时非常喜欢的一部动画，居然在土豆上看到了。

在个人电脑做如下操作：

ssh-keygen -d #生成公钥和私钥,此过程可以选择输入私钥密码

cat .ssh/id_dsa.pub | ssh user@remote “cat – >>.ssh/authorized_keys” #将公钥写到服务器

ssh-agent $SHELL

ssh-add

如果你设了私钥密码，此时输入你的私钥密码。

经过一年多的等待， mplayer 1.0pre8终于正式发布了。以下摘自发布说明：

t’s been more than one year since our last release and yes, we are still alive! Like always, the length of the ChangeLog clearly shows we have been lazy to release but not lazy to code.

First off, we have uncovered some new security bugs in the AVI, Real and MOV code so we urge you to upgrade in any case.

Given how old pre7 is by now, it’s strongly recommended to upgrade. We also recommend users to test and use the Subversion version when possible in order to both benefit from latest development, and report/fix bugs. Contrary to running a development kernel, it won’t eat your data or make your cat pregnant, but it will help us improve the overall quality of MPlayer.

Among the many features that have been added, it should be noted that libavformat now supports a greater variety of files. If you have a hard time playing some files, please try demuxing with libavformat (-demuxer lavf). MEncoder can also take advantage of libavformat, in order to, for example, create Flash videos.

There have also been many enhancements to the H.264 decoder to make it a lot faster and more error-resilient. More audio and video codecs are supported. Audio/Video synchronisation has been further improved, especially on Real streams and Vorbis.

And that’s not it yet! We have some more tricks for you up our sleeves for upcoming versions of MPlayer: experimental DVDnav (DVD menus) support and an experimental graphical user interface for our Windows port. Please join in the testing effort so that these features don’t remain experimental ;-).
