FFmpeg under Ubuntu 8.10

Details ffmpeg for Interpid (Jaunty)

Intrepid contains a pretty complete ffmpeg already, but you probably want to have ubuntu-restricted-extras installed which should pull in the 'unstripped' versions of several libraries. You can also look for them directly: libavcodec-unstripped-51, libavutil-unstripped-49 and libavformat-unstripped-52 from the multiverse repository.
Bug #291011 in Medibuntu: “Medibuntu ffmpeg for Ubuntu 8.10 Intrepid missing”

An "unstripped" build of ffmpeg is now included in the Ubuntu official repositories (intrepid/multiverse). You need to install the following libraries:

libavcodec-unstripped-51

libavdevice-unstripped-52

libavformat-unstripped-52

libavutil-unstripped-49

libpostproc-unstripped-51

libswscale-unstripped-0


Note that they should be automatically pulled in if you install ubuntu-restricted-extras (ou kubuntu-restricted-extras or xubuntu-restricted-extras).

Please, instead of blaming us, run "ffmpeg -formats" to find the correct
names (it seems they have changed).

[*] AMR support is not available in the Ubuntu package, because I
haven't had the time to update the patch which allows using libamr at
runtime. There is a candidate package available at
https://launchpad.net/~medibuntu-maintainers/+archive if you want to
check it.

netcat

My. Debian. » Something you should know…
Let’s say you want to establish a communication between two hosts (we will call them client and server); you could easily do it with:

server> nc -l -p 10000

client> nc server 10000

In this way, thanks to nc (a word that stands for netcat, that is cat over network) every string is typed by any of the parties is instantly transmitted to the other.
