Thanks for the "yum provides" tip, I was eventually able to make this work. Uninstalled ffmpeg.i386, and then installing vlc.i386 got everything installed (ffmpeg, gsm, vlc), with all libraries. I've a i386 system, not x86_64, and I tried: yum provides libavcodec.so.51 Which told me ffmpeg.i386 0.4.9-0.lvn.0.20.20051 livna-stable Matched from: /usr/lib/libavcodec.so.51 libavcodec.so.51 There is no such file - libavcodec.so.51 on my system, even though I've ffmpeg installed, doing a "yum install ffmpeg.i386" gives: Nothing to do But I suspected that was the root of the problem - when I try to run ffmpeg, I get this error: ffmpeg: error while loading shared libraries: libpostproc.so.0: cannot open shared object file: No such file or directory So, I there is something wrong with the ffmpeg install.... Did this to fix it: yum erase ffmpeg.i386 yum install vlc.i386 On 1/28/06, B Wooster <bwooster47@xxxxxxxxx> wrote: > I see vlc.i386 on livna-stable, and when I go to "yum install > vlc.i386", for the last few weeks, I always get the same set of > missing depenencies: > > Error: Missing Dependency: libavcodec.so.51 is needed by package vlc > Error: Missing Dependency: libavformat.so.50 is needed by package vlc > Error: Missing Dependency: libavutil.so.49 is needed by package vlc > Error: Missing Dependency: libpostproc.so.51.0.0 is needed by package vlc
