[packman] ffmpeg rpm

[Michel de Boer]

Hi,

I installed the following RPM from packman:

ffmpeg-0.4.9-8.pm.svn20070120

I think there is a problem with the build of ffmpeg.
I get this error:

ffmpeg: symbol lookup error: /usr/lib/libavformat.so.51: undefined
symbol: dlopen

ffplay works fine.

It seems ffmpeg is not linked against libdl (-ldl):

ldd /usr/bin/ffmpeg
        linux-gate.so.1 =>  (0xffffe000)
        libavformat.so.51 => /usr/lib/libavformat.so.51 (0xb7eb6000)
        libavcodec.so.51 => /usr/lib/libavcodec.so.51 (0xb7ad2000)

        libpthread.so.0 => /lib/libpthread.so.0 (0xb759e000)

ffplay is linked against libldl (-ldl) and hence it works:

HTH to solve the problem.
