10 years ago 你说的是 ffmpeg 最新版本还是你修改的这个 fmd 的最新版本？最新的 ffmpeg 我已经试过了，一样的结果。
或许你把自己的开发环境信息贴出来会让同学们更快的上手

10 years ago 嗯， 看起来 error 少了很多了 ：） 但还有一些问题，我试着把 -lswresample 放到最后也不成，一样的结果:

10 years ago 看起来好像在编码安装 ffmpeg 的时候没有把相应的 lib 放对位置还是需要在 Makefile 里面指定一下？

collect2: ld returned 1 exit statusdev 分支上的已经可以编译通过了！ :+1:
但运行的时候还是找不到 lib 文件，报错如下:
pi@raspberrypi ~/afmd $ ./fmd
./fmd: error while loading shared libraries: libjson-c.so.2: cannot open shared object file: No such file or directory我的这个库位置是 :
/usr/local/lib/libjson-c.so.2能不能运行下ldconfig然后再build一下
可能需要sudo

10 years ago dev branch最新的再试下吧，我把json-c也放到pkg-config的libs里了，这样希望可以尽量解决compatibility issues.

7 years ago 能帮我看一这个问题吗？这个是因为c的标准库的问题吗，我装的ffmpeg的最新版本，程序一编译就报错

7 years ago 不清楚你编译的是什么 - 不过看error好像是没有glibc的math lib的symbol。可以尝试在command line最后加上-lm

2 months ago 试试，调整 avutil 的链接顺序
结果如下：
