先试试命令行
sp-sc sop://sop.sopcast.org:3919/official/star_sports 8000 9000
mplayer http://127.0.0.1:9000
是否可以播放。

再在xterm下运行sopcast，看终端是否一会儿就停止输出了，如果是，说明sp-sc停止了。

先sp-sc sop://sop.sopcast.org:3919/official/star_sports 8000 9000
结果显示

url=sop://sop.sopcast.org:3919/official/star_sports
resourceID=28f3

mplayer http://127.0.0.1:9000
结果播放就闪掉，结果显示

再在xterm下运行sopcast，终端没有停止输出，仍是无法启动播放器

实验前先ps -axu检查是否有sp-sc进程，如果有，就用pkill sp-sc和kill -9 杀死。

Post by jazzi
先sp-sc sop://sop.sopcast.org:3919/official/star_sports 8000 9000
不知道怎么停止，就关掉终端后再输入

关掉终端会使sp-sc驻留内存。正确操作应该按ctrl-C退出。

mplayer http://127.0.0.1:9000
结果播放很流畅。

再在xterm下运行sopcast，终端没有停止输出，仍是无法启动播放器

运行sopcast后，再运行mplayer http://127.0.0.1:9000，看行否

检测端口使用情况：
nmap -sS -O -p- -PI -PT 127.0.0.1
结果通常有8000,9000

结果显示
mplayer http://127.0.0.1:9000
结果播放就闪掉，结果显示

闪掉说明sp-sc先提供了一会的媒体流，然后就中断了

输入mplayer http://127.0.0.1:9000后出现如下情况，
播放器没有启动

提了这么多问题，非常感谢楼主的解答

发现了一个解决办法，就是先输入:sopcast，选择所要看的频道

最后输入在MPlayer中打开网址http://127.0.0.1:9000
这样就能看了

dyte200

我在Ubuntu5.10 live cd下试了一下，sopcast运行基本正常。但信号驱动的gtk状态显示出问题了。信号是从一个子进程发出的。信号处理函数没有正常工作，这是我遇到的最奇怪的问题。
没有mplayer，我将player的命令行换成totem，但不支持wmv格式。

用两个终端，一个运行sp-sc，另一个运行mplayer

我用的也是MPlayer,奇怪的是为何sopcast无法启动MPlayer呢？？？
MPlayer播放前总有错误提示，具体见附件,错误提示窗口关掉之后播放正常

0.0.11 changlog: 不再采用子进程控制状态显示，改为时钟中断控制。
使用ubuntu的请帮助测试一下状态显示是否正确

我用的Ubuntu5.10
make 时有以下错误提示：

其他一切正常

只是一直有一个问题，CCTV1声音老是很嘈杂
