How to have dot separator in animategraphics filename?

Question

I really like to use dot separator as an universal separator, also in filenames, now trying to find a way to use it with animate package. Code where the filename gait.ataxia fails but also surrounding it with curly brackets fails: {gait.ataxia}

\documentclass{beamer}
\usepackage{animate}
\usepackage{graphicx}
\begin{document}
\begin{frame}
    \begin{figure}
        %https://tex.stackexchange.com/a/373780/13173
        % TODO fails here
        \animategraphics[controls,autoplay,loop]{2}{gait.ataxia}{00}{16}
    \end{figure}            
\end{frame}
\end{document}

Output: ! Package animate Error: None of the files

Output with surrounding extra curly brackets: ! Argument of \end has an extra }.

Adding \usepackage{grffile}, clear the errors but the animation itself is full-stop where action links do not respond. Without filename.dot structure, the animation works normally.

Output: animation in full-stop + animation link actions do not respond

Hm. Works out for me. I will put together an example on ShareLaTeX. – AlexG Jun 15 '17 at 10:53

Well, on ShareLaTeX it works even without grffile. – AlexG Jun 15 '17 at 11:05
I am using TeXLive-2017 too (with packages updated this morning). grffile does the trick. – AlexG Jun 15 '17 at 11:11
Works now on my system too with/without grffile after TeXLive 2017 package updates! How is grffile necessary here? Can it improve the stability? I want to understand why the code did not work in my earlier system state. – Léo Léopold Hertz 준영 Jun 15 '17 at 11:14

I seem to use a different mirror site for TL updates. I test without grffile tomorrow. – AlexG Jun 15 '17 at 11:16

No change, grffile still needed. – AlexG Jun 16 '17 at 13:35
What is your output without grffile? – Léo Léopold Hertz 준영 Jun 16 '17 at 13:39

No output file. It does not compile. ! LaTeX Error: Unknown graphics extension: .file00000.png. – AlexG Jun 16 '17 at 13:59
