[vlc-devel] configure: error: Missing libav or FFmpeg

[qma ster]

I got a really helpful advice from Rémi Denis-Courmont at VLC forums thread
- https://forum.videolan.org/viewtopic.php?f=13&t=137096

    Make sure that "pkg-config --modversion libavcodec" works.
    If not, then FFmpeg is essentially not installed.

This command gave me the following error message:

    Package libavcodec was not found in the pkg-config search path.
    Perhaps you should add the directory containing `libavcodec.pc'
    to the PKG_CONFIG_PATH environment variable
    No package 'libavcodec' found

Checked my PKG_CONFIG_PATH variable - it was empty :

    echo $PKG_CONFIG_PATH

Then I searched at /usr directory for libavcodec.pc , and found it:

    find /usr -name "libav*.pc"
    /usr/lib/pkgconfig/libavutil.pc
    /usr/lib/pkgconfig/libavcodec.pc
    /usr/lib/pkgconfig/libavfilter.pc
    /usr/lib/pkgconfig/libavformat.pc
    /usr/lib/pkgconfig/libavdevice.pc
    /usr/lib/pkgconfig/libavresample.pc
    /usr/lib64/pkgconfig/libavc1394.pc

Now all I needed to do is to add these path: /usr/lib/pkgconfig/ , and also
/usr/lib64/pkgconfig/ just in case, to PKG_CONFIG_PATH (could be done
through bashrc or any other way). After that, "pkg-config --modversion
libavcodec" outputs a version number of libavcodec instead of error, and
vlc could be configured and built without any problems! ^_^
