Question

我正在尝试安装ffmpeg和ffmpeg-php，当我尝试使用make时出现错误。我试图找到它的底部，但它让我难过。我试着找到哪个文件引用了swscale.h但没有任何运气。有没有人遇到过这个错误？

看起来无法找到swscale.h。您应该检查该文件是否包含在您的FFmpeg安装中，如果是，则ffmpeg-php具有使用-I/path/to/includes指定的正确路径集来查找它。如果没有，您可以添加正确的目录，如：

CFLAGS=-I/path/to/ffmpeg/includes ./configure
make

如果找不到swscale.h，可能是FFmpeg和ffmpeg-php之间存在一些版本不匹配。前者非常积极地开发，ffmpeg-php期望找到的碎片可能不再存在。检查ffmpeg-php的文档，看看它是否与特定版本绑定。
