Error when installing ffmpeg-php

Question

I am trying to install ffmpeg and ffmpeg-php and am getting an error when I try to use make. I've tried to get to the bottom of it but it has me stumped. I tried finding which file has references to swscale.h but didn't have any luck. Has anyone encountered this error before?

Answer 1

It looks like it can't find swscale.h. You should check to see if that file was included with your FFmpeg install, and, if so, that ffmpeg-php has the correct set of paths specified with -I/path/to/includes to find it. If it doesn't, you can add the correct directory with something like:

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

If you can't find swscale.h, it could be that there's some version mismatch between FFmpeg and ffmpeg-php. The former is pretty actively developed, and pieces that ffmpeg-php expects to find might no longer be present. Check the docs for ffmpeg-php to see if it's tied to a particular version.

Installing libswscale-dev helped me on Debian Squeeze
