ffmpeg and libx264 not installing correctly

[cyocum]

I am on Xubuntu 17.04 (recently updated but this has been going on for a while) and when I install ffmpeg via apt and try to run it I get the following error:



ffmpeg: error while loading shared libraries: libx264.so.142: cannot open shared object file: No such file or directory


When I do ldd on the ffmpeg installed I see:



libx264.so.142 => not found


I checked my ldconfig to see what it thought was installed I get:



libx264.so.148 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libx264.so.148
libx264.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libx264.so


So, I have absolutely no idea where or why ffmpeg when installed via apt thinks that there should be a libx264.so.142. I have also done a find in /usr and cannot find libx264.so.142 anywhere on my system. Does anyone have any suggestions on what I should try next?

which ffmpeg


/usr/local/bin/ffmpeg

You have installed an older unpackaged version of ffmpeg to /usr/local/bin so get rid of it. Also check in /usr/local/* for any other ffmpeg files to remove.
To test as is run this, ffmpeg (repo version) will start

/usr/bin/ffmpeg

Great. Thanks. I removed the /usr/local/bin version and a few other ffmpeg related files but I am still getting the same error just with the /usr/bin/ffmpeg now.

[mc4man]

what do these show

ls -R /usr/local/lib |grep libavcodec

ls -R /usr/lib |grep libavcodec

ldd /usr/bin/ffmpeg

I finally got the hint from your questions that I had even more old libraries from a bad old ffmpeg compile installed in /usr/local/lib so I removed them and now it works. Thanks!
