i able play webcam video response in video view json response weather underground "camurl" so:

http://www.wunderground.com/webcams/cadot1/902/show.html

the url video need play embedded in html code url so:

https://www.wunderground.com/webcams/cadot1/1216/video.html?month=11&year=2016&filename=current.mp4

is there way url json response "camurl"? i've heard of term "html scraping", possible embedded video url json response html page?

this full json response looks webcam:

    {     "handle": "mahouser",     "camid": "mahousercam1",     "camindex": "1",     "assoc_station_id": "kcacamar18",     "link": "http://",     "linktext": "michael houser",     "cameratype": "foscam fi9900p",     "organization": "",     "neighborhood": "camarillo hills",     "zip": "93010-12",     "city": "camarillo",     "state": "ca",     "country": "us",     "tzname": "america/los_angeles",     "lat": "34.24947357",     "lon": "-119.03993988",     "updated": "2016-11-10 20:57:24",     "updated_epoch": "",     "downloaded": "2016-11-08 20:38:48",     "isrecent": "1",     "currentimageurl": "http://icons.wunderground.com/webcamramdisk/m/a/mahouser/1/current.jpg?t=1478812080",     "widgetcurrentimageurl": "http://icons.wunderground.com/webcamramdisk/m/a/mahouser/1/widget.jpg?t=1478812080",     "camurl": "http://www.wunderground.com/webcams/mahouser/1/show.html" }

i've looked @ jsoup , read documentation can't figure out how needed url. here how url looks in html:

    <td class="day">     <div class="row">     <div class="small-2 medium-5 columns">     <a href="/history/airport/kajo/2016/11/15/dailyhistory.html" class="day-num">     15     </a>     </div>     <div class="small-10 medium-7 columns">     <img src="//icons.wxug.com/i/c/v4/clear.svg" alt="clear" class="right" />     </div>     </div>     <div class="calthumb">     <a href="http://icons.wunderground.com/webcamramdisk/c/a/cadot1/902/current.jpg?1479239986" rel="lightbox[webcam]" title="">     <img src="http://icons.wunderground.com/webcamramdisk/c/a/cadot1/902/current-thumb.jpg?1479239986" width="100" height="75" alt="" title="click view time-lapse video day." />     </a>     </div>     <p><a href="video.html?month=11&year=2016&filename=current.mp4" class="videotext">view video</a></p>     </td>

how can "current.mp4" url within html code?

there lot of possible ways, here simple solution:

  1. retrieve html code jsoup:

    document doc = jsoup.connect("http://www.wunderground.com/webcams/cadot1/902/show.html").get();

  2. then, retrieve elements class videotext:

    elements elements = doc.getelementsbyclass("videotext");

    this give list of entries. select 1 ends current.mp4.

  3. to retrieve current.mp4 url:

    for (element link : elements) {     string linkhref = link.attr("href");     // linkhref contains video.html?month=11&year=2016&filename=current.mp4     // todo check if linkhref ends current.mp4 }
