i have a xmoov.php pseudo-flv-streaming script setup on a site and it works, but when you start loading a video, you cannot navigate the site anymore until the video is completely loaded.... why is that??
PHP Code:
<?php
$require_login=1;
include("includes/config.php");
//------------------------------------------------------------------------------------------
// MEDIA PATH
//------------------------------------------------------------------------------------------
// you can configure these settings to point to video files outside the public html folder.
//
// points to server root
define('XMOOV_PATH_ROOT', '');
//
// points to the folder containing the video files.
define('XMOOV_PATH_FILES', './videos/');
//------------------------------------------------------------------------------------------
// BEHAVIOR
//------------------------------------------------------------------------------------------
//
//set to TRUE to use bandwidth limiting.
define('XMOOV_CONF_LIMIT_BANDWIDTH', FALSE);
//
//set to FALSE to prohibit caching of video files.
define('XMOOV_CONF_ALLOW_FILE_CACHE', TRUE);
//------------------------------------------------------------------------------------------
// BANDWIDTH SETTINGS
//------------------------------------------------------------------------------------------
// these settings are only needed when using bandwidth limiting.
//
// bandwidth is limited my sending a limited amount of video data(XMOOV_BW_PACKET_SIZE),
// in specified time intervals(XMOOV_BW_PACKET_INTERVAL).
// avoid time intervals over 1.5 seconds for best results.
//
// you can also control bandwidth limiting via http command using your video player.
// the function getBandwidthLimit($part) holds three preconfigured presets(low, mid, high),
// which can be changed to meet your needs
//
//set how many kilobytes will be sent per time interval
define('XMOOV_BW_PACKET_SIZE', 90);
//
//set the time interval in which data packets will be sent in seconds.
define('XMOOV_BW_PACKET_INTERVAL', 0.3);
//
//set to TRUE to control bandwidth externally via http.
define('XMOOV_CONF_ALLOW_DYNAMIC_BANDWIDTH', TRUE);
//------------------------------------------------------------------------------------------

// accessed by your player
