我已经为 mp4 格式的视频创建了字幕,我想将其作为 FLV 文件放到网上。是否可以将字幕与flv文件一起播放而无需将它们集成到视频图像中,因此将它们保持为srt格式?

我找到了一种方法,使用 JW flv 播放器:
- 将您的 .srt 文件转换为 xml 文件(下面的 php 代码)
- 然后添加一个指向您的 xml 文件的变量“captions”:
s0.addVariable("captions","path/to/subtitles.xml");
活的例子在这里
// script to convert multi-line srt caption files to new-format (02-05-08) tt XML caption files
$use_cdata_tags = true;
$debug_output = true;
// the directory to write the new files in
// it must exist, be writeable, and be outside of the directory that is being scanned
$new_directory = '../temp/';
/////////////////////////////////// no user configuration below this \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
// get filename or scan directory if it's a directory
$filename = (isset($_GET["filename"])) ? strval($_GET["filename"]) : "./";
// read each file into an array
$it = new RecursiveDirectoryIterator("$filename");
foreach(new RecursiveIteratorIterator($it) as $file)
{
// debug('Filename', $file); exit;
// debug('Ext', substr(strtolower($file), (strlen($file) - 4), 4));// exit;
// debug - only use test file
// if($file == '.\multi-line_test_file.srt')
// check for .srt extension
if(substr(strtolower($file), (strlen($file) - 4), 4) == '.srt')
{
$ttxml = '';
$full_line = '';
if($file_array = file($file))
{
// write tt , head, and div elements for the new file
$ttxml .= "";
$ttxml .= "\n";
$ttxml .= " \n";
$ttxml .= " \n";
$ttxml .= " \n";
$ttxml .= " \n";
foreach($file_array as $line)
{
$line = rtrim($line);
// debug('Line', $line);
// get begin and end
// 00 : 00 : 32 , 000 --> 00 : 00 : 37 , 000
if(preg_match('/(\d\d):(\d\d):(\d\d),(\d\d\d) --> (\d\d):(\d\d):(\d\d),(\d\d\d)/', $line, $match))
{
$begin = $match[1] . ":" . $match[2] . ":" . $match[3] . "." . $match[4];
$end = $match[5] . ":" . $match[6] . ":" . $match[7] . "." . $match[8];
$full_line = '';
}
// if the next line is not blank, get the text
elseif($line != '')
{
if($full_line != '')
{
$full_line .= '
' . $line;
}
else
{
$full_line .= $line;
}
}
// if the next line is blank, write the paragraph
if($line == '')
{
// write new paragraph
// Nothing is going on.
if($use_cdata_tags)
{
$ttxml .= " \n";
}
else
{
$ttxml .= " " . $full_line . "\n";
}
// debug('Text', $line);
// debug('ttxml', $ttxml); exit;
$full_line = '';
}
}
// write ending tags
$ttxml .= " \n";
$ttxml .= " \n";
$ttxml .= "\n";
// write new file
$new_file = $new_directory . substr($file, 0, (strlen($file) - 4)) . '.xml';
$fh = fopen($new_file, 'w') or die('Can\'t open: ' . $new_file);
fwrite($fh, $ttxml) or die('Can\'t write to: ' . $new_file);
fclose($fh);
}
}
}
function debug($title, $value)
{
global $debug_output;
if ($debug_output)
{
print "";
if (is_array($value))
{
print $title . ":\n";
print_r($value);
}
else
{
print $title . ": " . $value;
}
print "
\n";
}
}
?>
