Compiling NVIZ from SVN trunk, I get following problem:

If I manually add -lavformat, the compilation works ok.

The package is lib64ffmpeg51-devel-0.4.9-3.pre1.7407.10plf2007.1 (Mandriva)
which contains
rpm -ql lib64ffmpeg51-devel-0.4.9-3.pre1.7407.10plf2007.1 | grep lib64
/usr/lib64/libavcodec.so
/usr/lib64/libavformat.so
/usr/lib64/libavutil.so
/usr/lib64/libpostproc.so
...

Any ideas how to automate that -lavformat is included?

the new ffmpeg movie format-by-extension code needs libavformat which
may come in a separate package to libavcodec.
(libavformat-dev and libavcodec-dev packages on Debian)

I don't know much about ./config scripts, but the attached is an
untested cut & paste job which might work. (I don't know about
-lavutil,..)

I don't know much about ./config scripts, but the attached is an

LOC_CHECK_LIBS(avcodec, avcodec_init, FFMPEG, $FFMPEGLIBPATH, FFMPEGLIB,-lavutil $MATHLIB)
+LOC_CHECK_LIBS(avformat, av_set_parameters, FFMPEG, $FFMPEGLIBPATH, FFMPEGLIB,-lavutil $MATHLIB)

I initially thought that this would replace FFMPEGLIB, but it will
actually append to it, so it should be okay.

Works nicely.
