# How to include video with subtitle .mkv file in beamer

I would like to add video format .mkv in frame

i tired the following code but with no luck is there any solution I need to add this particular extension of video (.mkv) because it conains video and subtitles

\documentclass{beamer}
\usepackage{multimedia}

\begin{document}

\begin{frame}
\movie[width=8cm,height=4.5cm]{test}{m.mkv}
\end{frame}

\end{document}


ffmpeg -i m.mkv -vf subtitles=m.mkv m.mp4

will embed the subtitles in a .mp4 file which might work with media9.
