Playing a local video in UIWebView gives EXEC_BAD_ACCESS

Question

Playing a local video in UIWebView gives EXEC_BAD_ACCESS

I am new to iPhone development and trying to run local video in UIWebView. I am loading the UIWebView using the loadHTMLString method, and the video URL is //...documents/uploads/../ax.mp4. The application crashes when I click the play button of the video player in web browsing. The video file is downloaded by the application from my http server to the document folder. If I specify the path to the file on the server, it will play correctly.

This is the HTML snippet in the body tag that I upload to webview:

<div style=\"float:left;margin:5px 10px 5px 5px;\">
  <embed  qtsrc=\"%@\" type=\"application/x-shockwave-mp4\"  qtsrcdontusebrowser=\"true\" id=\"video\" src=\"%@\"  ></embed>
</div>

I also tried with the HTML5 tag, its snippet below:

<div style=\"float:left;margin:5px 10px 5px 5px;\">
  <video id =  \"video\" align=\"left\" src=\"%@\" controls=\"controls\">your  browser does not support the video tag</video>
</div>

The crash report has this for a crashed thread:
