我有一個ffmpeg轉換器,可將視頻轉換爲mp4。轉換後,我想刪除原始視頻以保存文件空間。 我嘗試使用unlink($file_path)
,但它說權限被拒絕。使用取消鏈接從服務器中刪除文件
到目前爲止,視頻轉換並生成轉換的縮略圖。
$ffmpeg = 'ffmpeg';
$output = dirname(__DIR__).'/uploads/thumbs/'.$_file.'.jpg';
$input = dirname(__DIR__).'/uploads/'.$file;
$mov = new ffmpeg_movie($input);
$d = $mov->getDuration();
$iscopy = $mov->getCopyright();
$h = $mov->getFrameHeight();
$w = $mov->getFrameWidth();
$pos = ceil((int)$d /3);
$size = $w.'x'.$h;
$i = explode('.',$input);
$o = $i[0].'.mp4';
if(ceil($d) < 1200){
if($ext != 'mp4'){
$cmd = "ffmpeg -i $input -vcodec h264 -acodec aac -strict -2 $o";
shell_exec($cmd);
}
$cmd = "ffmpeg -ss $pos -i $o -an -s $size $output";
shell_exec($cmd);
$total_time += $pos;
$succedeed[] = array('name' => $name,'file' => 'thumbs/'.$_file.'.jpg', 'type' => 'mp4');
if(file_exists('../uploads/'.$file)){
unlink('../uploads/'.$file);
}
}else{
$failed[] = array('name' => $name, 'file' => $file, 'error' => 'Video length cannot exceed 20mins.');
}
該文件的路徑是這樣的:
unlink(../uploads/fdbc716e18173d4fe895c6d0b03365df1399237360.avi)
我已經試過this (question),this (question)和大量的谷歌搜索,都沒有成功:
chdir($FilePath); // Comment this out if you are on the same folder
chown($FileName,465); //Insert an Invalid UserId to set to Nobody Owner; for instance 465
$do = unlink($FileName);
if($do=="1"){
echo "The file was deleted successfully.";
} else { echo "There was an error trying to delete the file."; }
