Question

我想在codeigniter中使用ffmpeg将上传的音频文件转换为mp3。我已将ffmpeg文件放在我的codeigniter根文件夹中。这里是我的代码控制器，

$this->upload->initialize(
    array(
        "upload_path"   => './uploads/',
        "overwrite"     => FALSE,
        "max_filename"  => 300,
        "encrypt_name"  => TRUE,
        "remove_spaces" => TRUE,
        "allowed_types" => "mp3|amr",
        "max_size"      => $this->settings->info->file_size,
    )

);

if ( ! $this->upload->do_upload('audio_file')) {
    $error = array('error' => $this->upload->display_errors());
    $this->template->jsonError(lang("error_97") . "<br /><br />" .
    $this->upload->display_errors() . "<br />" . mime_content_type($_FILES['audio_file']['tmp_name']));
}

// $data = $this->upload->data();
$data                 = array('upload_data' => $this->upload->data());
$video_path          = $data['upload_data']['file_name'];
$directory_path      = $data['upload_data']['file_path'];
$directory_path_full = $data['upload_data']['full_path'];
$file_name           = $data['upload_data']['raw_name'];

exec("ffmpeg -i " . $directory_path_full . " " . $directory_path . $file_name . ".mp3");

$file_name = $file_name . '.' . 'mp3';

$audioid = $this->feed_model->add_audio(
    array(
        "file_name" => $file_name,
        "file_type" => $data['file_type'],
        "extension" => $data['file_ext'],
        "file_size" => $data['file_size'],
        "userid"    => $this->user->info->ID,
        "timestamp" => time()
    )
);

接下来使用ffmpeg.Or将音频文件转换为mp3的代码是什么？还有其他方法可以吗？

您无法使用PHP转换文件，但可以使用 ffmpeg

$ ffmpeg -i input.mp4 output.mp3

在PHP中，您可以使用exec()执行上述命令

exec("ffmpeg -i /path/to/input.mp4 /path/to/output.mp3");

将任何音频文件转换为mp3格式的codeigniter ffmpeg
