        <?php
        $curl = curl_init('https://api.twitch.tv/kraken/channels/CHANNELNAME/videos');
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        $result = curl_exec($curl);
        $i = curl_getinfo($curl);
        curl_close($curl);
        $videos = json_decode($result);

Then

<iframe 
    src="http://player.twitch.tv/?video=<?php echo $videos->videos[0]->_id; ?>" 
    height="720" 
    width="1280" 
    frameborder="0" 
    scrolling="no"
    allowfullscreen="true">
</iframe>
