New issue 299 by aiyapan....@gmail.com: Webp image can't open
https://bugs.chromium.org/p/webp/issues/detail?id=299

Hi, I am using the following code for convert jpg to webp.

$ii = imagecreatefromjpeg('Lighthouse.jpg');
// Save the image
imagewebp($ii, 'Lighthouse.webp');
// Free up memory
imagedestroy($ii);

The output will be produced by run this program and I open that webp image format on Window Photo Viewer, the web image can't open. But other webp images are open. Can you please give me a solution

Hi, which library/version/language are you using ? It does not seem to be from the official WebP library. Thx.

My full code of convert jpg to webp is below,

In this case, some images seems to be crashed and some images are display well at the time of run this page. Again i reload the page previously display images also crashed.

$images = array('fb_instant.jpg','Lighthouse.jpg','Penguins.jpg','Sample Jpeg Image.jpeg');

foreach ($images as $value) {

$file = 'images/'.$value;
$file_extension = pathinfo($file, PATHINFO_EXTENSION);
$file_name = basename($value, '.'.$file_extension);
$image= imagecreatefromjpeg($file);
ob_start();
imagejpeg($image,NULL,100);
$cont= ob_get_contents();
ob_end_clean();
imagedestroy($image);
$content = imagecreatefromstring($cont);
imagewebp($content,'images/webp/'.$file_name.'.webp');
imagedestroy($content);

This is a bug-report form for libwebp library. You should try to identify a bug in the library, if possible.
Providing samples and exact reproduction steps, as well as exact operating conditions, would be helpful too.

Otherwise this discussion should be carried out either in StackOverflow (where there seem to be some progress made, btw) or the PHP authors (and/or posting to webp-d...@webmproject.org).

Thanks.
