It seems that changing in FindFFMPEG.cmake<br>
get_filename_component(FFMPEG_INCLUDE_DIR ${FFMPEG_INCLUDE_DIR} PATH)<br>
<br>
by<br>
get_filename_component(FFMPEG_INCLUDE_DIR ${FFMPEG_INCLUDE_DIR}

<br>
make it work on my configuration and on an ubuntu installation. I mean
it detects that it is a new version (and that should normally compile
afterwards).<br>
<br>
Can you confirm that it works on your machine?<br>

each libs header in a separate directory, such as libavcodec/avcodec.h.<br>

What is supposed to be FFMPEG_INCLUDE_DIR in my configuration?

I have just updated and tried again, same errors:<br>

<br>
ffmpeg headers are installed as follows:<br>
<br>
/usr/include/ffmpeg/libavcodec/avcodec.h<br>
/usr/include/ffmpeg/libavformat/avformat.h<br>
/usr/include/ffmpeg/libavutil/avutil.h<br>
/usr/include/ffmpeg/libswscale/swscale.h<br>
<br>
They seem seem to be found during the cmake configuration time, which
is supposed to be for recent version of ffmpeg (It may be a wrong
assumption here).<br>
The error sounds like it assume my system has an older version of
ffmpeg...<br>

<div>The intention of my change was to get it working with
where
apt-get installs the headers/libraries on Debian. :-/ Can you share
where the ffmpeg headers and libraries are installed on your machine,
particularly avcodec,h avformat.h avutil.h swscale.h (this one may not
exist at all) and the equivalent libs (libavcodec, libavformat,
libavutil, libswscale? Also if you try updating and doing a build right
now does the error go away? I checked in a few more changes this
morning. <br>

<br>
With the recent changes in FindFFMPEG.cmake, vtk is not compiling
anymore with FFMPEG on my machine. It was perfectly working until last
night...<br>

<br>
I can set up a nightly build to track/solve this error if needed.<br>
<br>
My machine is a Linux Fedora Core 12 (64 bits) with ffmpeg installed
using yum.<br>
<br>
The commit message on FindFFMPEG.cmake states "COMP: further fixes to
get FFMPEG to be found properly on Linux."<br>
Is there any distribution dependency on how ffmpeg is installed?<br>
