I am using the following params via ffmpeg to convert videos to webm format: <pre class="prettyprint"><code>-c:v libvpx -qmin 0 -qmax 50 -crf 4 -b:v 2M -c:a libvorbis -q:a 10 </code></pre> However it takes lot of time (more than 5 minutes) just to convert 5 MB video. Can I write some other params to make the conversion fast?

<code>ffmpeg -i input -vcodec libvpx -cpu-used -5 -deadline realtime out.webm</code> The <code>-cpu-used</code> and <code>-deadline</code> options control speed/quality for libvpx codec. See <code>ffmpeg -h full</code> for details in the <code>libvpx-vp8 encoder AVOptions</code> section.
