Could NOT find FFmpeg (missing: FFmpeg_INCLUDE_DIRS) in Mint17

Please specify the ffmpeg header include directories via FFmpeg_INCLUDE_DIRS (assuming you have ffmpeg installed on your system)

I installed ffmpeg by "apt-get install ffmpeg", but I do not have any packages like ffmpeg-dev, so what would that header directory should be look like?

I undertake the same problem. Do we have to download the ffmpeg source code or something ?

[bevinhex]

I only wanted to test the library to know what exactly it is, but after frustrating with the compiling process, I already gave up, looks like we need ffmpeg souce code, and specify it by FFmpeg_INCLUDE_DIRS, I didn't tried it myself, you can give it a try.
And I hate to compile download the ffmpeg stuff, since it should be in the repository

Ended up using Qt instead. Much less effort into the getting of the tools. I agree with bevinhex, those "third parties" should be redistributed, or at least redirected to how to get them.

I made an effort to include most dependencies in the source tree, with the exception of ffmpeg and openssl which aren't convenient for redistribution.

There are two options here:

Please either build ffmpeg on your system by following one of the many guides out there. Once installed, CMake should configure ffmpeg automatically thanks to the pkgconfig files, otherwise just specify the FFmpeg_INCLUDE_DIRS and FFmpeg_LIBRARY_DIRS manually.

The other alternative is to disable ffmpeg support entirely by setting WITH_FFMPEG to OFF. This will also exclude many of the media related modules from the output build.

Hope this helps.
