How about this.
$str = "video_get_current_url\":\"Copy frame link\",\"url240\":\"http:\\\/\\\/cs534515v4.vk.me\\\/u163220668\\\/videos\\\/1c1b06aec9.24‌​0.mp4\",\"url360\":\"http:\\\/\\\/cs534515v4.vk.me\\\/u163220668\\\/videos\\\/1c1b06aec9.36‌​0.mp4\",\"jpg\":\"http:\\\/\\\/cs534515.vk.me\\\/u163220668\\\/video\\\/l_8a5b0712.jpg\",\"‌​ip_subm\":1,\"nologo";
preg_match('/\\"Copy\sframe.*"jpg\\"/is', $str, $matches);
var_dump($matches);
Output:
array(1) {
[0]=>
string(199) ""Copy frame link","url240":"http:\\/\\/cs534515v4.vk.me\\/u163220668\\/videos\\/1c1b06aec9.24‌​0.mp4","url360":"http:\\/\\/cs534515v4.vk.me\\/u163220668\\/videos\\/1c1b06aec9.36‌​0.mp4","jpg""
}
Edit:
And then, if you wanted to extract the video url's from that:
preg_match_all('/(https?:.*?\.mp4)/', $matches[0], $id);
//Then echo out the url's
foreach ($id[0] as $url) {
// the preg_replace strips out the double backslashes.
echo preg_replace('/\\\\/', '', $url)."<br />";
}
Output:
http://cs534515v4.vk.me/u163220668/videos/1c1b06aec9.24‌​0.mp4
http://cs534515v4.vk.me/u163220668/videos/1c1b06aec9.36‌​0.mp4
