php视频上传和ffmpeg不会创建缩略图 [英] php video upload and ffmpeg won't create a thumbnail
问题描述
我正在尝试为我的项目制作视频上传功能.但是我在 ffmpeg 部分中遇到了问题. ffmpeg 已安装在我的服务器上.但是我无法得到任何缩略图.我尝试使用以下代码创建缩略图:
I am trying to make a video upload feature for my project. But I have a problem with ffmpeg section. ffmpeg is already installed on my server. But i can not get any thumbnail. I have try to create thumbnail using the following code:
$videoa = exec("/usr/bin/ffmpeg -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4 2>&1");
$videob = exec("/usr/bin/ffmpeg -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");
但是当对var_dump($videoa);和var_dump($videob);
string(74)" https://mywebsite.com/uploads/video/ey1kXNew_video. flv : 输入/输出错误字符串(0)""
string(74) "https://mywebsite.com/uploads/video/ey1kXNew_video.flv: Input/output error" string(0) ""
如果我像这样使用shell_exec:
$videoa = shell_exec("/usr/bin/ffmpeg -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4");
$videob = shell_exec("/usr/bin/ffmpeg -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");
和var_dumps()给我NULL NULL.
请帮助我我在哪里错了.
Please help me where am I wrong.
这是我完整的视频上传代码:
And here is my full video upload code:
$valid_formats = array("mp4","MP4","flv");
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST") {
$name = $_FILES['uploading']['name'];
$size = $_FILES['uploading']['size'];
if(strlen($name)) {
$ext = strtolower(pathinfo($name, PATHINFO_EXTENSION));
$name = alphaID(microtime(true) * 10000).'_video';
if(in_array($ext,$valid_formats)) {
if($size<(50024*50024)) {
$GetVideoName = $name;
$video_ext=$ext;
$tmp = $_FILES['uploading']['tmp_name'];
if(move_uploaded_file($tmp, $videoPath.$GetVideoName.'.'.$video_ext)) {
$videoUrlp = $base_url.'uploads/video/'.$GetVideoName;
$videoa = exec("/usr/bin/ffmpeg -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4 2>&1");
$videob = exec("/usr/bin/ffmpeg -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");
echo var_dump($videoa);
echo var_dump($videob);
} else {
echo "Fail upload folder with read access.";
}
} else
echo "Image file size max 1 MB";
} else
echo "invalidvieo";
} else
echo "Please select image..!";
exit;
}
我也这样测试过:
echo exec("/usr/bin/ffmpeg -i $videoUrlp.flv -ar 22050 -ab 32 -f flv -s 780x400 $videoUrlp.$video_ext");
echo exec("/usr/bin/ffmpeg -i $videoUrlp.$video_ext -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $videoUrlp.png 2>&1");
我看到以下回声
video:71kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.000000%
video:71kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.000000%
，再尝试一次，我得到此注释: https://mywebsite.com /uploads/video/1547892356_video.flv :连接被拒绝
and another try then I get this note: https://mywebsite.com/uploads/video/1547892356_video.flv: Connection refused
echo exec("/usr/bin/ffmpeg -i $videoUrlp.flv -ar 22050 -ab 32 -f flv -s 780x400 $videoUrlp.$video_ext");
echo exec("/usr/bin/ffmpeg -i $videoUrlp.$video_ext -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $videoUrlp.png 2>&1");
这是最后一个shell_exec输出:
Here is last shell_exec Output:
$local = 'https://website.com/uploads/video/'.$GetVideoName.'.'.$video_ext;
$localTumb = 'https://website.com/uploads/video/'.$GetVideoName.'.png';
echo shell_exec("/usr/bin/ffmpeg -i $local -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $localTumb 2>&1");

推荐答案
如果您使用的是https，则必须为ffmpeg配置ssl支持(
If you are using https, your ffmpeg has to be configured with ssl support (ffmpeg over https fails).
