I'm trying for the first time to install ffmpeg2theora using scons. The scons command gives me the following error:

scons: Reading SConscript files ...
Checking for pkg-config... (cached) yes

Checking for libavcodec libavformat libavdevice libpostproc libswscale... (cached) yes
Package libavcodec was not found in the pkg-config search path.
Perhaps you should add the directory containing `libavcodec.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libavcodec' found
OSError: 'pkg-config --cflags --libs "libavcodec"' exited 1:

return function(self, self.backtick(command))
File "/usr/lib/scons-1.1.0/SCons/Environment.py", line 545:
raise OSError("'%s' exited %d" % (command, status))



"locate libavcodec" gives:

"pkg-config --cflags --libs "libavcodec"" returns:

My $PKG_CONFIG_PATH is:

The config.log has:

I have uninstalled and reinstalled ffmpeg twice. I get the same results using ffmpeg2theora svn and tarball.

I am not familiar with scons or python and I have no clue what to do. Any help would be appreciated.

avcodec.h used to be installed in ffmpeg/avcodec.h, but some time near the beginning of this year it was moved to libavcodec/avcodec.h. It would appear that ffmpeg2theora isn't aware of the change.

The easiest thing to do to get it to compile would be to find in all the source files where you have "#include <ffmpeg/avcodec.h>" and change it to "#include <libavcodec/avcodec.h>"

Thank you for the suggestion. But grep finds no instances of avcodec.h in any file in the source tree.

I wonder if the warning about libavcodec not being found in PKG_CONFIG_PATH isn't a false lead, since when I run "pkg-config --cflags --libs "libavcodec"" I get the following:I would guess that one of the components of libavcodec is missing, so it's failing to recognize the package.

Did you install ffmpeg via "get_ffmpeg_svn.sh"?

I had already installed ffmpeg via svn. I did use get_ffmpeg_svn.sh to download and compile ffmpeg in the source directory but didn't actually install that one.

Edit to add: I should say by saying I'd already installed ffmpeg via svn I should say that I had just updated the svn files and installed it 10 minutes before I started on ffmpeg2theora.

Edited again: Looking again at your output I should note that when installing ffmpeg I did not enable faac, a52, or x264. I don't know what the -lz is

Just uninstalled ffmpeg and reinstalled it via the script. Got the same results.

I tried recreating your issue, but after uninstalling the currently installed ffmpeg (which was ffmpeg-svn_13024-i586-2gsb) and building via get_ffmpeg_svn.sh I was able to successfully build ffmpeg2theora without a problem. I also got the same output as you now when running "pkg-config --cflags --libs "libavcodec"" after installing the new ffmpeg.

Which distro are you using? Maybe you're missing the ffmpeg development libraries, and pkg-config is using outdated cache information. I would suggest reinstalling ffmpeg that's provided, and check for ffmpeg-dev* package as well.

I really appreciate the time and effort. It is odd. I've used both of these programs before. Something in the upgrade broke it, I guess. Maybe I can try to find the old versions.

I'm using Linux From Scratch 6.3. Everything I have was compiled from source.
