Jwplayer视频播放器无法正常工作
[英]Jwplayer video player not working
问题描述
I am trying to set up Jwplayer video player but nothing is appearing, no video player is being displayed at all. 
我正在尝试设置Jwplayer视频播放器，但是什么也没出现，根本没有显示视频播放器。 What am I doing wrong in the set up as I have followed the instructions but the video file is coming from a database and the mysqli is definitely correct: 我按照说明进行操作时，我在做错什么，但是视频文件来自数据库，而mysqli绝对正确：
<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>
Ok what is happening is that when I use the $GET method to get the video's file name from a previous page (using a hyperlink), it opens up a new page and the url is this: 好的，是发生了什么事，当我使用$ GET方法从上一页（使用超链接）获取视频的文件名时，它会打开一个新页面，其网址为：
http://helios.hud.ac.uk/u05454444/Mobile_app/previewvideo.php?filename=sample_mpeg4_5.mp4
In the database when I try to retrieve the video file, it is stored in the database as VideoFiles/sample_mpeg4_5.mp4 . 当我尝试检索视频文件时，在数据库中，该文件以VideoFiles/sample_mpeg4_5.mp4形式存储在数据库中。
This is because the videos are stored in the VideoFiles folder 这是因为视频存储在VideoFiles文件夹中
Now at moment it is display a black square where the video player is suppose to be stating: 现在，此时显示一个黑色方块，视频播放器应该在该方块中指出：
Error loading player:
No playable sources found
Do I need to include the js file of jwplayer.html5.js , am i missing any other files that may be needed or is it something else which is the problem? 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，或者是其他问题吗？

IMAGE: 图片：
Below is displaying image code: 下面显示图像代码：
If I select a hyperlink known as Tulips_3.png , then the url is displays in url is this: 如果我选择一个称为Tulips_3.png的超链接，则该URL显示为：
http://helios.hud.ac.uk/u05545444/Mobile_app/previewimage.php?filename=Tulips_3.jpg
Yet all I do is retrieve the filename using the get method, find the image in database with its directory in front ImageFiles/ as the image in database is saved as ImageFiles/Tulips_3.png and then display the image using source, code is below: 但是我要做的就是使用get方法检索文件名，在数据库中找到其目录位于ImageFiles/前面的图像，因为数据库中的图像另存为ImageFiles/Tulips_3.png ，然后使用源代码显示该图像，代码如下：
<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>

UPDATE 2 : 更新2 ：
<script type="text/javascript">
jwplayer("myElement").setup({
file: "<?php echo $dbVideoFile; ?>",
image: "example.jpg",
});
</script>
echo 'this is $dbVideoFile: '.$dbVideoFile;
output: this is $dbVideoFile: VideoFiles/sample_mpeg4_5.mp4` 输出：这是$ dbVideoFile：VideoFiles / sample_mpeg4_5.mp4`
Hope it's help. 希望对您有所帮助。

You have a typo in your script: 您的脚本中有错字：
<script type="text/javascript">
jwplayer("myElement").setup({
file: "<php echo $videoPath ?>",
image: "example.jpg",
});
</script>
should be: 应该：
<script type="text/javascript">
jwplayer("myElement").setup({
file: "<?php echo $videoPath ?>",
image: "example.jpg",
});
</script>
Note the extra questionmark "?" 注意额外的问号“？” in the starting php-tag. 在开始的php-tag中。
