Missing library, I think I have found it!?!


I have installed slackware 11, along with mplayer and kplayer from hte linuxpackages.net website.

When I try to play a wmv in kplayer it complains that it can't find libavformat.so.1

afetr a breif search on hte internet all references to libavformat (and libavcodec) point to a program called ffmpeg.

Does this mean that I need to install ffmpeg to get that required library? looking on linuxpackages.net there is an ffmpeg package but the description says it has further requirements, do all those requirements need installing as well? and is this what is meant by dependance hell?

I have downloaded them from linuxpackages.net but I can't remember whether I have installed them. would these then give me libavformat.so.1?

You need the codecs for all the various media including wmv. So I would install those and see if it works.

ffmpeg is a funny old beast and I had mega trouble getting it working with transcode for dvd::rip if you do need it download it using cvs from the ffmpeg web site and run configure with --enable-shared parameter. if you have any further problems you might want to check this link out. http://www.linuxforums.org/forum/lin...suse-10-a.html.

It has nothing to do with MPlayer but it may help.

libavformat.so.1 is not part of mplayer codecs.

If this library is indeed part of ffmpeg, then there's a slackbuild available here:

I haven't installed it, but given the source I'm sure it works.
