它只是output.Could somoone的一部分帮助我的工作人员？我在这里，thx。

Its only a part of output..Could somoone help me with that staff? I stucked here, thx.

我给了一些关于ld的信息--verbose -l avformat：

Also I give u some info about ld --verbose -l avformat:

attempt to open /usr/i686-linux-gnu/lib32/libavformat.so failed

一切都将是avutil的问题....所有未定义的引用来自文件libavutil。但我不知道为什么和做什么。

Everything is going to be problem with avutil....all undefined reference comes from files of libavutil. But I have no idea why and what to do.
