Answer 1

Looks like you need to escape the backslash,

$pageContent = preg_replace_callback( '/\[hdvideo ([^]]*)\\o]/i', 'video_shortcodeplace', $pageContent );

Answer 2

Open \wp-content\plugins\contus-video-gallery\hdflvvideoshare.php file and find add_filter('the_content', 'videogallery_pagereplace'); and replace with the following code.

add_shortcode('videohome','video_homereplace');
add_shortcode('videomore','video_morereplace');
add_shortcode('hdvideo','video_shortcodereplace');

Answer 3

Replace

$pageContent = preg_replace_callback('/\[hdvideo ([^]]*)\o]/i', 
                                     'video_shortcodeplace', 
                                     $pageContent 
                                    );

with

$pageContent = preg_replace_callback('/\[hdvideo\s*.*?=(\d+)\]/i', 
                                     'video_shortcodeplace', 
                                     $pageContent
                                    );
