ffmpeg shared libraries

dbc001 · 09-02-2006, 12:29 PM

Trying to get ffmpeg to work, which i downloaded from linuxpackages.net. here's what happens when i run it:

Code:

# /usr/bin/ffmpeg
/usr/bin/ffmpeg: error while loading shared libraries: libavutil.so: cannot open shared object file: No such file or directory

anybody know where to get libaviutil.so? i've been googling it for hours with no luck - i can't even tell what package it's a part of...

thanks in advance!

Don't know if ldd would help. This is my output:

Code:

        linux-gate.so.1 =>  (0xffffe000)
        libm.so.6 => /lib/tls/libm.so.6 (0xb7faa000)

I think its a core part of ffmpeg or transcode, sounds like you are missing a symlink or something. Check to see if you have libavutil.so.1 or libavutil.so.2 or something similar.
You might want to reinstall or install mplayer as that usually includes the libav* libraries.

alright, here's the output from ldd:

Code:

# ldd /usr/bin/ffmpeg
        libavformat.so => /usr/lib/libavformat.so (0x40030000)
        libavcodec.so => /usr/lib/libavcodec.so (0x400a7000)

        libfaac.so.0 => not found
        libmp3lame.so.0 => not found

I went ahead and installed MPlayer and I can't tell if it installed the files that I'm looking for... (I didn't have MPlayer installed before - I just need commandline access to ffmpeg so that my gallery will build thumbnails for videos. I'm not really sure what to do next...

From the mplayer page with instructions for compiling from svn it says:

"The sources will contain the libav* directories from FFmpeg so you don't need to download these separately."

The source also contains libfaad2 so that might solve one of your other deps.
