It will make more sense if you look at \CGG{}'s ffmpeg config directory and the \CGG{} menus at the same time. It is meant to include everything necessary for complete understanding. You will be able to personalize your own options files without knowing all of the information included below if you know the basics. The word encoding is used interchangeably with the word rendering. The possible combinations for ffmpeg options files are literally combinatorial -- that is a lot (factorial!). The allowed media file format / codec choices are much more flexible than you might realize. When the ffmpeg design was initially added, some parameter files which describe the choices which the program uses had to be created. There are way too many to enumerate in the deliverable \CGG{} package. Some quite detailed information for how ffmpeg options work is given here and hopefully, enough basics for simple understanding. It may all seem complicated at first, but will become obvious. +AppImage does not provide this capability unless you use the workaround as described in the Appendix \nameref{cha:faq_problems_workarounds}. \subsection{File naming convention}% \label{sub:file_naming_convention} -AppImage does not provide this capability. In \CGG{}'s ffmpeg configuration directory you will see files as listed and described below. File type and extension names are the key for \CGG{}'s use of ffmpeg. Basically the \texttt{.opts} file extension represents options; \texttt{.dfl} represents defaults; and all the rest are media types. For example one media type is quicktime so that \texttt{*.qt} file names would be the \textit{quicktime} choices. In the file names below, \textit{ext} refers to a set of files with file names matching the \texttt{*.ext} file extension. And \textit{typ} refers to a type of format / codec combination used, that is, the media type. +In \CGG{}'s ffmpeg configuration directory you will see files as listed and described below.

Currently only the most common codecs, such as MPEG-1, MPEG-2, MPEG-4, H.264 /MPEG-4 and h265 (hevc), are accelerated/optimized by the graphics card to play these particular video formats efficiently. The other formats are not optimized so you will see no performance improvement since the CPU will handle them as before, just as if no hardware acceleration was activated. There are many different graphics cards and computer systems setup, so you will have to test which specific settings work best for you. So far this has been tested at least with Nvidia, Radeon, and Broadwell graphics boards on some AMD and Intel computers; depending on the graphics card, two to ten times higher processing speeds can be achieved. However, most graphic operations are single-threaded so that performing the operations in the hardware may actually be slower than in software making use of multiple CPUs, which frequently multi-thread many operations simultaneously.
