[libmicrohttpd] Stopping MJPEG streams

[David J Myers]

Hi,

I’m having some trouble with my streaming MJPEG webserver. It’s basically about how a client webpage can cause the stream to stop and trigger the MHD_Content_Reader_free_Callback.

 

The webserver uses MHD_create_response_from callback with MHD_SIZE_UNKNOWN, and the Daemon is set for 2 second client timeouts.

 

So the webpage starts the stream with this line of html.

 

    <td rowspan="2" align="center" valign="top" style="border-right:dashed 1px grey;"><div id="div1" style="width:640px; height:480px; border:solid 1px red; position:relative; left:0px"><img src="mjpg/video.cgi?view=1" name="main1" /> </div>

 

Then there is a button on the webpage to stop the video, which causes this _javascript_ function to execute

 

function stop()

{

       eval('document.main1.src="">);

}

 

The blank jpeg is drawn into the div, but the webserver continues to stream the video and the reader free callback isn’t triggered.

 

Does anyone know how I can stop the stream without totally navigating away from the page?

 

Thanks and regards
