Push XML on T38G

[cptjack]

It seems like you have the same issue that I encountered a while ago; static images do get displayed correctly, but dynamic images don't. It took me quite a while to realize that the Yealink T38G phone needs to have the Content-Length header set or the image won't be displayed...

I solved this with a PHP script by adding the appropriate Content-Length header to the output like this:

PHP Code:

<php
$dst = imagecreatetruecolor(480,272);
imagealphablending($dst, true);

$src = imagecreatefromjpeg("http://ipcamera/snapshot.cgi");
imagecopyresampled ($dst, $src, 0, 0 , 0, 0, imagesx($dst), imagesy($dst) , imagesx($src), imagesy($src));

// Yealink phone needs the Content-Length header
// Get the Image Data Length
ob_start(); // start a new output buffer
   imagejpeg( $dst, "", 90 );
   $ImageData = ob_get_contents();
   $ImageDataLength = ob_get_length();
ob_end_clean(); // stop this output buffer

//header('Last-Modified: '.gmdate('D, d M Y H:i:s', filemtime($fn)).' GMT', true, 200);
header("Content-type: image/jpeg") ;
header("Content-Length: ".$ImageDataLength);
echo $ImageData;

// Free up memory
imagedestroy($src);
imagedestroy($dst);
?>

So you will need an intermediate script, if the camera doesn't have the Content-Length header by default. I hope this solves your problem as well. Please, let us know if it does or not
