shell_exec  ("ffmpeg -i \"$FILENamE.flv\" -ss 00:00:04 -f image2 \"$FILENAME.jpg\"");

我很遗憾地说我没有测试过,所以先试试吧.

编辑：为了好玩,我把它变成了一个功能.这里是：

<?PHP
 
function GetThumbnailFileName($FileName,$ScreenShortSecond = 10) {
    $VDOLastModifiedDate = filemtime($FileName);
    $Thumbnail_FileName  = sPRintf("%s-(%s::%02d).jpg",$FileName,$VDOLastModifiedDate,$ScreenShortSecond);
     
    if (!file_exists($Thumbnail_FileName)) {
        $FFMPEG_Command = sprintf(
            "ffmpeg -i \"%s\" -y -ss \"00:00:%02d\" -f image2 \"%s\" > /dev/null 2>&amp;1",0 + $ScreenShortSecond,$Thumbnail_FileName
        );
        system($FFMPEG_Command);
    }
     
    if (!file_exists($Thumbnail_FileName))
        return null;
     
    return $Thumbnail_FileName;
}
 
$FileName  = "test.flv";
$Thumbnail = GetThumbnailFileName($FileName);
if ($Thumbnail != null)
     echo "Thumbnail file is: \"$Thumbnail\"\n";
else echo "Fail creating a Thumbnail of \"$FileName\".";
 
?>

此功能还会缓存缩略图,并确保在修改VDO时重新创建更新缩略图.
