As far as I know, animate never, and most likely will never work with tex4ht.

It does not even work with pdf readers embedded in browsers. i.e. if you open the
pdf inside the browser, the animation will not run.

I think it works only with standalone adobe pdf reader and may be with 1-2 other
standalone pdf readers.

This is what I do to run animations in HTML

----------------
\documentclass[12pt]{book}

\usepackage{graphicx}
\ifdefined\HCode
\else
\usepackage{animate}
\fi

\usepackage{lipsum}

\begin{document}

\ifdefined\HCode
\ScriptEnv{html}
      {\NoFonts\hfill\break}
      {\EndNoFonts}

     \HCode{
     <IMG SRC="f.gif" ALT="some text" WIDTH=750 />
     }
\else
\animategraphics[controls,loop,width=3in]{3}{f}{1}{10}
\fi

\lipsum[1-3]
\end{document}
