Problem with installation - make step about displaycluster HOT 10 OPEN

Looks like a version problem in ffmpeg. We are using a pretty old version here - 1.1.2, I think, and it looks like ffmpeg has moved ahead with non-backwards compatible changes. In particular, I think PIX_FMT_RGBA has been changed to AV_PIX_FMT_RGBA and https://ffmpeg.org/pipermail/libav-user/2016-February/008841.html might help with the error: ‘avcodec_alloc_frame’ was not declared in this scope problem.

Hi, Leonardo - Its included with the source code in the ‘dependencies’ directory. Extract it, and assuming you have Qt (4.8.x - I haven’t tried anything else) installed and accessible, cd in and qmake, then make all. Greg Gregory D.

Sorry - pretty swamped here. Yes, there are PythonQt CMAKE variables you’ll need to set - PythonQt_INCLUDE_DIR and PythonQt_LIBRARY Set PythonQt_INCLUDE_DIR to the src subdir of the PythonQt source tree. Greg Gregory D.

I had some issues with not finding Python.h as well but I set CPLUS_INCLUDE_PATH so it moved ahead but still PythonQt.h is not found. Is there a variable that needs to be set for this or something to change in the cmake modules? — You are receiving this because you commented.

Bet you need to enable Python support in the CMAKE confguration - the screen-saver stuff (which I recently added) really should be dependent on that being set. Greg Gregory D.

When you run cmake (or ccmake), there’s an option called ‘ENABLE_PYTHON_SUPPORT’ I think you should see it if you use ‘ccmake’ - the GUI version - or if you are using the command-line cmake version, set -DENABLE_PYTHON_SUPPORT=ON Gregory D.
