[英]Jwplayer video player not working
我正在嘗試設置Jwplayer視頻播放器,但是什么也沒出現,根本沒有顯示視頻播放器。 我按照說明進行操作時,我在做錯什么,但是視頻文件來自數據庫,而mysqli絕對正確:
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<title>Preview Video</title>
<script type="text/javascript" src="jquery/jwplayer.js"></script>
</head>
<body>
<?php
$getvideo = 'VideoFiles/' . $_GET['filename'];
$videoquery = "SELECT VideoFile FROM Video WHERE (VideoFile = ?)";
if (!$videostmt = $mysqli->prepare($videoquery)) {
// Handle errors with prepare operation here
}
// Bind parameter for statement
$videostmt->bind_param("s", $getvideo);
// Execute the statement
$videostmt->execute();
if ($videostmt->errno)
{
// Handle query error here
}
$videostmt->fetch();
$videostmt->close();
?>
<div id="myElement">Loading the player...</div>
<script type="text/javascript">
jwplayer("myElement").setup({
file: "<php echo $getvideo ?>",
image: "/uploads/example.jpg",
});
</script>
**UPDATE:**
Current code:
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<title>Preview Video</title>
<script type="text/javascript" src="jquery/jquery-1.7.min.js"></script>
<script type="text/javascript" src="jquery/jwplayer.js"></script>
</head>
<body>
<?php
$getvideo = 'VideoFiles/' . $_GET['filename'];
$videoquery = "SELECT VideoFile FROM Video WHERE (VideoFile = ?)";
if (!$videostmt = $mysqli->prepare($videoquery)) {
// Handle errors with prepare operation here
}
// Bind parameter for statement
$videostmt->bind_param("s", $getvideo);
// Execute the statement
$videostmt->execute();
if ($videostmt->errno)
{
// Handle query error here
}
$videostmt->bind_result($dbVideoFile);
$videostmt->fetch();
$videoPath='http://domain.com/videos/'.$dbVideoFile;
$videostmt->close();
?>
<div id="myElement">Loading the player...</div>
<script type="text/javascript">
jwplayer("myElement").setup({
file: "<php echo $videoPath ?>",
image: "example.jpg",
});
</script>
</body>
好的,是發生了什么事,當我使用$ GET方法從上一頁(使用超鏈接)獲取視頻的文件名時,它會打開一個新頁面,其網址為:
http://helios.hud.ac.uk/u05454444/Mobile_app/previewvideo.php?filename=sample_mpeg4_5.mp4
當我嘗試檢索視頻文件時,在數據庫中,該文件以VideoFiles/sample_mpeg4_5.mp4
形式存儲在數據庫中。
這是因為視頻存儲在VideoFiles
文件夾中
現在,此時顯示一個黑色方塊,視頻播放器應該在該方塊中指出:
Error loading player:
No playable sources found
我是否需要包括jwplayer.html5.js
的js文件,我是否缺少任何可能需要的其他文件,或者是其他問題嗎?
螢火蟲:
使用Firebug,我下面有以下HTML,其中包含視頻播放器的顯示html:

圖片:
下面顯示圖像代碼:
如果我選擇一個稱為Tulips_3.png
的超鏈接,則該URL顯示為:
http://helios.hud.ac.uk/u05545444/Mobile_app/previewimage.php?filename=Tulips_3.jpg
但是我要做的就是使用get方法檢索文件名,在數據庫中找到其目錄位於ImageFiles/
前面的圖像,因為數據庫中的圖像另存為ImageFiles/Tulips_3.png
,然后使用源代碼顯示該圖像,代碼如下:
<body>
<?php
$getimage = 'ImageFiles/' . $_GET['filename'];
$imagequery = "SELECT ImageFile FROM Image WHERE (ImageFile = ?)";
if (!$imagestmt = $mysqli->prepare($imagequery)) {
// Handle errors with prepare operation here
}
// Bind parameter for statement
$imagestmt->bind_param("s", $getimage);
// Execute the statement
$imagestmt->execute();
if ($imagestmt->errno)
{
// Handle query error here
}
$imagestmt->bind_result($dbImageFile);
$imagestmt->fetch();
$imagestmt->close();
?>
<p><img alt="<?php echo $dbImageFile; ?>" height="200" width="200" src="<?php echo $dbImageFile; ?>"></p>
</body>
更新2 :
<script type="text/javascript">
jwplayer("myElement").setup({
file: "<?php echo $dbVideoFile; ?>",
image: "example.jpg",
});
</script>
echo 'this is $dbVideoFile: '.$dbVideoFile;
輸出:這是$ dbVideoFile:VideoFiles / sample_mpeg4_5.mp4`
希望對您有所幫助。
您的腳本中有錯字:
<script type="text/javascript">
jwplayer("myElement").setup({
file: "<php echo $videoPath ?>",
image: "example.jpg",
});
</script>
應該:
<script type="text/javascript">
jwplayer("myElement").setup({
file: "<?php echo $videoPath ?>",
image: "example.jpg",
});
</script>
注意額外的問號“?” 在開始的php-tag中。
