Test filter-fps-cfr failed. Look at tests/data/fate/filter-fps-cfr.err for details.
make: *** [fate-filter-fps-cfr] Error 1

我发现是crc失败了，代码如下：

uint32_t crc = av_adler32_update(0, pkt->data, pkt->size);

我现在很困惑，谢谢你的回答。

分析：Yasm 是汇编编译器，ffmpeg 为了提高效率，使用了 MMX、SSE 等汇编指令，因此如果系统没有安装 yasm，就会报上述错误。解决方法：安装 yasm 编译器。
