Question

我正在尝试使用getid3将APIC图片写入mp3文件。这是代码;

$cover = "/home/user/public_html/artwork/cover.jpg";
$TagData['attached_picture'][]=array(
'picturetypeid'=>2, // Cover. More: module.tag.id3v2.php -> function APICPictureTypeLookup
'description'=>'cover', // text field
'mime'=>'image/jpeg', // Mime type image
'data'=>$cover // Image data
);

但它不起作用。图像大小约为1.5 MB。我应该把它调整大小吗？

我哪里错了？

Answer 1

观看他们在网站上的演示：http://www.getid3.org/source/demo.write.phps

代码片段：

$fd = fopen($_FILES['userfile']['tmp_name'], 'rb')
$APICdata = fread($fd, filesize($_FILES['userfile']['tmp_name']));
fclose ($fd);

$imagetypes = array(1=>'gif', 2=>'jpeg', 3=>'png');
if (isset($imagetypes[$APIC_imageTypeID])) {
    $TagData['attached_picture'][0]['data']          = $APICdata;
    $TagData['attached_picture'][0]['picturetypeid'] = $_POST['APICpictureType'];
    $TagData['attached_picture'][0]['description']   = $_FILES['userfile']['name'];
    $TagData['attached_picture'][0]['mime']          = 'image/'.$imagetypes[$APIC_imageTypeID];
}

似乎数据键需要是图像内容，而不仅仅是图像文件的路径。所以在你的情况下，它应该是这样的：

$cover = "/home/user/public_html/artwork/cover.jpg";
$fd = fopen($cover, 'rb')
$APICdata = fread($fd, filesize($coverFile));
fclose ($fd);

$TagData['attached_picture'][]=array(
'picturetypeid'=>2, // Cover. More: module.tag.id3v2.php -> function APICPictureTypeLookup
'description'=>'cover', // text field
'mime'=>'image/jpeg', // Mime type image
'data'=>$APICdata  // Image data
);

注意：这只是在快速浏览一下演示代码之后，我没有使用过这个库或测试过这段代码。

Answer 2

GetID3需要为数据发送文件的内容，而不是文件路径。然后只有它能够将它们嵌入到文件中。尝试

$cover = "/home/user/public_html/artwork/cover.jpg";
$TagData['attached_picture'][]=array(
    'picturetypeid'=>2, // Cover. More: module.tag.id3v2.php -> function APICPictureTypeLookup
    'description'=>'cover', // text field
    'mime'=>'image/jpeg', // Mime type image
    'data'=> file_get_contents($cover) // Image data; not the file name
);

测试和工作：）

Answer 3

我在源代码中找到了这个：

case 'APIC':
    // 4.14  APIC Attached picture
    // Text encoding      $xx
    // MIME type          <text string> $00
    // Picture type       $xx
    // Description        <text string according to encoding> $00 (00)
    // Picture data       <binary data>

因此图片数据必须是二进制的。

这个对我来说很长时间了：

    $TagData = array(); //your other tags
    $fd = fopen($albumPath, 'rb');
    $APICdata = fread($fd, filesize($albumPath));
    fclose($fd);

    if($APICdata) {
        $TagData += array(
            'attached_picture' => array(0 => array(
                'data'          => $APICdata,
                'picturetypeid' => '0x03',
                'description'   => 'cover',
                'mime'          => image_type_to_mime_type($albumExifType)
            ))
        );
    }
    //and write the tags to file

对于那些只需更新其ID3标签（包括专辑封面）的人来说，上面的代码工作得很好你需要让getID3库工作。这个答案基于JacopKane的答案，所以归功于他

使用getid3（id3v2）将APIC写入mp3文件
