I'm trying to create thumbnails from external videos, mostly MP4s and FLVs. I'm using FFmpegPHP. I already have the thumbnail generation working fine, however, I need to load the video entirely on my server first. Would it be possible to stream only a small part of the video then extract the thumbnail from that?
Here's the code I have so far:
require_once PRIV . 'Vendor/FFmpegPHP/FFmpegAutoloader.php';
// Download the whole video.
$video = file_get_contents($_PUT['video']);
$file = 'path_to_cache';
file_put_contents($file, $video);
$movie = new FFmpegMovie($file);
// Generate the thumbnail.
$thumb = $movie->getFrame($movie->getFrameCount() / 2);
$thumb->resize(320, 240);
imagejpeg($thumb->toGDImage(), 'path_to_thumb');
Anyone has a suggestion?
EDIT
As Brad suggested, here is the updated code:
$file = CACHE . 'moodboard_video_' . rand();
$fh = fopen($file, 'w');
$size = 0;
curl_setopt($ch, CURLOPT_URL, $_PUT['video']);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_WRITEFUNCTION, function($ch, $data) use($fh, &$size){
$length = fwrite($fh, $data);
if($length === FALSE) {
return 0;
} else {
$size += $length;
}
// Downloads 1MB.
return $size < 1024 * 1024 * XXXXXX ? $length : 0;
});
curl_exec($ch);
fclose($fh);
curl_close($ch);
// Create the thumbnail.
$thumb = $movie->getFrame(XXXXXX);
$thumb->resize(static::DEFAULT_THUMBNAIL_WIDTH, $thumb->getHeight() / $thumb->getWidth() * static::DEFAULT_THUMBNAIL_WIDTH);
$image = $thumb->toGDImage();
imagejpeg($image, PRIV . static::THUMBNAILS_PATH . $item->getLastInsertIdentifier() . '_' . static::DEFAULT_THUMBNAIL_WIDTH);
