Hi
I have two boxes running crunchbang, one has been 'infected' with
software from non standard repos.
Downgrading (removing, installing) ffmpeg to the older, official version
on the infected box I get this:
"ffmpeg: Symbol `av_pix_fmt_descriptors' has different size in shared
object, consider re-linking"
My question is: how do I figure out what library(ies) I need to downgrade?

`ldd /usr/bin/ffmpeg` lists all libs used by the binary. It must be one
of the libs listed there, but which of those is harder to find out.
objdump (1) or ltrace (1) can provide detailed information, but simply
re-installing all the ones 'ldd' prints (and possibly also their
dependencies, run ldd recursively) should do it.
av_pix_fmt is in libavutil - at least for the official ffmpeg from
ffmpeg.org. But the situation in res libav.org and ffmpeg.org is tricky.
The problem could also have arisen by mixing the two, or installing one
of them in /usr/local/

Thanks, very useful!
av_pix_fmt is in libavutil
Ok, so I removed libavutil and installed it again (already removed the
offending repo in sources.list.d/) and now everything seems to work just
fine!
Thanks for the help!

By the way on Debian (so I guess this would apply also to Crunchbang)
compiling the 'real' ffmpeg is rather straightforward. I did it by
following the official guide [1].

JFTR. Don't confuse Debian and Ubuntu. Although Ubuntu is *based* on
Debian, they are not the same.

The permalink might be confusing. The title of the guide is:
"Compile FFmpeg on Ubuntu, Debian, or Mint"
Merry Christmas :)
