                <p>x262 is a <b>free software</b> <b>library</b> and <b>application</b> for encoding video streams into the

            <h2>Features Overview</h1>
            <p>x262 is an MPEG-2 encoder based on the best-in-class features of x264.<br />
               It also has the big advantage that the codec is simple enough for people new to video-compression to get involved.<br />
