title: Converting an HLS (m3u8) to MP4
body: <p>Can anyone advise on how to construct an <code>MP4</code> file from an <code>HLS</code> stream (the reverse of what you usually want)? Say I have the m3u8 - is there a straightforward way of getting a single <code>MP4</code> using <code>FFMPEG</code> or some other tool?</p>
