Re: Accessing shockwave/flash video via HttpUnit?

Use HTTPUnit to capture the webpage that contains your embedded flash
video. Since the video file is nothing but a web resource sitting on
some server, download it to your local directory. Once you have this
file on your local drive you can do a benchmark comparison with your
existing file that you want to compare against which is also accessible
locally. 
I am attaching the code to download this video file. 

Assuming you have a webResponse object called "currentPage"

     private static final String SRC_MARKER   = "src=";
      String text;
            try
            {
                text = currentPage.getText();
            }
            catch (IOException e)
            {
                throw new GenericException("Unable to read response
page: " 
                + e.getMessage(), e);
            }
        
            String lower = text.toLowerCase();
            URL pageURL = currentPage.getURL();    
            StringBuffer notFoundImages = new StringBuffer();
        
            for(int i = 0; (i = lower.indexOf(SRC_MARKER, i + 1)) != -1;
)
            {
                int start = i + SRC_MARKER.length();
                char quoteChar = text.charAt(start);
                int end = text.indexOf(quoteChar, ++start);
                String src = text.substring(start, end);
         
                try
                {
                    URL imageURL = new URL(pageURL, src);
                    String urlString = imageURL.toString();
                    InputStream in;

Subject: [Httpunit-develop] Accessing shockwave/flash video via
HttpUnit?


I'm looking for a means to apply HttpUnit to capture a shockwave/flash
video that may be embedded in a web page. I recognize that HttpUnit can
identify an HTML object of the form:

<object width="425" height="350"><param name="movie"
value="http://www.website.com/v/IwD25nkGV1A"></param>
<param name="wmode" value="transparent"></param><embed
src="http://www.website.com/v/IwD25nkGV1A"
type="application/x-shockwave-flash" wmode="transparent" width="425"
height="350"></embed></object>

But how can I capture the video stream that arises from the URL and
compare against a known reference? The media stream resides within our
firewall. Thx.
