Installing ffDiaporama Development Version in Fedora 23

Preliminary
As the maintainer for ffDiaporama is not maintaining the project, i decided to try out the development version which tends to be ahead of the stable version.

 Select the Linux button from ffDiaporama Landing site (http://ffdiaporama.tuxfamily.org/?page_id=3635) .

We shall see this page.



There is a script for Fedora, but i can't seem to get it to work. Hence, i downloaded the zip files found under the section "Other cases".

Download the three files, Resource package – Source files package,Application package – Source files package, Texturemate extension – Source files package.



Installing Qmake and other prequisites

 Go for Qt5


Installation prerequisites:
     sudo dnf groupinstall development-tools
     sudo dnf install gcc-c++
     sudo dnf install qt5-qtbase-devel qt5-qttools-devel qt5-qtsvg-devel qt5-qtbase qt5-qttools qt5-qtsvg qt5-qtimageformats qt5-qtmultimedia-devel qt5-qtmultimedia qt5-qtdeclarative-devel
     sudo dnf install ffmpeg ffmpeg-devel
     sudo dnf install SDL SDL-devel SDL_mixer-devel SDL_mixer
     sudo dnf install exiv2 exiv2-devel
      

     cd
     test -d bin || mkdir bin
     cd bin
     ln -s /usr/bin/qmake-qt5 qmake
     ln -s /usr/bin/lrelease-qt5 lrelease

NB: If previous "symbolic link" (to earlier Qt, e.g. Qt3 and Qt4, exists, please remove them (e.g. sudo rm qmake) and relink again (e.g. ln -s /usr/bin/qmake-qt5 qmake)


Editing Header files (cDeviceModelDef.h & -EncodeVideo.cpp)

NB: Prior to install "ffDiaporama.zip" if you r using ffmpeg 2.8.7 (or above, which i believe applicable to higher version)

#define RESAMPLE_MAX_CHANNELS SWR_CH_MAX
to
    #define RESAMPLE_MAX_CHANNELS 32

in cDeviceModelDef.h

Add in
   VideoStream->time_base                  = VideoFrameRate;  
 //ffmpeg 2.8.7 and above
right after the line
   VideoStream->codec->time_base           = VideoFrameRate;
in _EncodeVideo.cpp.

Thumbdrive and Oracle VirtualBox

Safe Removal of Hdd/Thumbdrive

Safely remove Hdd/Thumbdrive on Linux Mint Debian Edition

Sometimes the eject option is not available to safely remove a external storage device, the way to do it manually is to issue the following command:

Installing Oracle VirtualBox

Resolving gpg-keyserver error updating VirtualBox

Advice: follow the instruction on https://www.virtualbox.org/wiki/Linux_Downloads to update the repository list in your /etc/apt/sources.list

NB: An error likely to surface when updating Oracle VirtualBox on Debian-based distribution (including Ubuntu):  "Error! Could not locate dkms.conf file.
File: does not exist."

1) Simply delete the previous version folder in /var/lib/dkms/vboxhost/ for e.g. (/var/lib/dkms/vboxhost/5.X.XX)

2) issue the command "sudo /etc/init.d/vboxdrv setup" and the error is gone.
