<div>Dear David</div>
<div> </div>
<div>Thank you for your help, I have sorted out the problem. I did not include the ffmpeg include path in the file in the proper way, thank you. Double checked and the problem was solved. Thanks again. <br><br> </div>

${FFMPEG_INCLUDE_DIR}/ffmpeg/avformat.h. This can happen if ffmpeg did<br>not compile and install properly, or if the setting of the variable<br>does not match the location of the file.<br><br>Either the command prompt or editing the Cache can work, but I<br>
wouldn't recommend it. A better way to make settings is to use CMake's<br>UI to choose them interactively. To do that, run "ccmake ." in your<br>paraview build directory and run through the settings. When you change<br>
a setting and configure, for example turning VTK_USE_FFMPEG_ENCODER<br>on, the UI will prompt you to for any any other settings that depend<br>on that choice, for instance FFMPEG_INCLUDE_DIRECTORY. Running cmake<br>from the command prompt and editing the cache directly are better for<br>
scripting and do not have as nice a mechanism to help make sure the<br>settings are sane. The UI also has tab completion, which is<br>particularly helpful to make sure that the directory you are setting<br>exists. So make sure to choose the include directory in the ffmpeg<br>
install tree, and not the include/ffmpeg directory, also make sure<br>that the file avformat.h exists in the include/ffmpeg directory.<br><br>About the svn thingy, I would not recommend it. Since I put that copy<br>of the the ffmpeg source onto the vtk web site, the ffmpeg developers<br>
have substantially improved the library. Unfortunately some of their<br>changes broke backwards compatibility. This might be the source of<br>your problem. Their is an open bug on the vtk bug tracker to make<br>VTK/ParaView work with more recent ffmpeg, but until that is resolved<br>
we are stuck with ffmpeg from a particular date. To make a long story<br>short, compile the version of ffmpeg from the tar ball and not a<br>version from the ffmpeg repository.<br><br>n 2/19/08, Cally <<a href="mailto:kalpana0611@gmail.com">kalpana0611@gmail.com</a>> wrote:<br>
