ffmpeg installation problems Ubuntu 12.04

I am a newbie on Ubuntu therefore when I want to install a new program I just follow the instructions step by step and I usually succed. Not this time.

I first installed serviio as instructed on serviio-wiki and is running.
(serviio start/running, process 1075)
The Serviio Console is also working and my TV is listed.

Then I followed the Building FFmpeg Guide :
Install “Essential Build Tools and Libraries” – done – no apparent errors
Install “Yasm” – done – no apparent errors
Build and install x264 – done – no apparent errors (Please note that I did disable OpenCL)
Build and install librtmp – done – no apparent errors

When I tryed to build and install ffmpeg (again following exactely the instructions given on wiki)
due to errors the installetion failed.

I removed x264 (using dpkg -r x264) then I reinstalled it but I had the same errors again!

Any idea of what I am doing wrong?

ERROR: libx264 not found
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

Thanks for the tip "npuser"
I did the following:

Checked where x264 is located

luigi@luigi-IXTREME-MC-9600:~$ whereis x264
x264: /usr/local/bin/x264

added : include /usr/local/bin to /etc/ld.so.conf
ran: ldconfig

removed x264

Compiled/installed x264 with –disable-opencl

Unfortunately trying to compile and install FFmpeg gives the same errors.

I have found libx264.a which is an AR archive in the src/x264 directory, do you know what is it?

[npuser]

What do you get when you run 'x264' from a terminal? you should see following if x264 is in path and installed correctly.

  Code:

x264 [error]: No input file. Run x264 --help for a list of options.


if the x264 is installed correctly then opencl is the issue. Try following.

  Code:

cd ~/src
git clone git://git.videolan.org/x264
cd x264
./configure --enable-static --disable-opencl
make
sudo checkinstall --pkgname=x264 --pkgversion="3:$(./version.sh | \
    awk -F'[" ]' '/POINT/{print $4"+git"$5}')" --backup=no --deldoc=yes \
    --fstrans=no --default

Problem solved!

I rermoved and then reinstalled everything, ffmpeg is now compiled. I do not know what was wrong.

Serviio is stil not detected by my TV but I will keep searching for an answer.

Thanks a lot npuser
