[FFmpeg-user] "ERROR: libx264 not found" Ubuntu 11.10

[medi]

Hi,

It seems ffmpeg cannot find libx264, one way to get sure that libx264
is installed is to use the following command :
"whereis libx264.so"
the result should be something like:
libx264: /usr/lib/libx264.so

To install x264, you can do it like this:
sudo apt-get install x264 libx264-dev

you can also build libx264 from source, then it may install library
files in '/usr/local/lib' instead, you should check /etc/ld.so.conf
and add '/usr/local/lib
' if it is not already there, then you should run 'sudo ldconfig' to
refresh library paths.

I'm using a different Linux distribution, but I guess the above
procedure should work on Ubuntu. I hope it goes well. I'm eager to
know the result.
