Is there any way that I can speed up the ffmpeg processing time
20 mai 2020, par Ahmed Al-RayanI am facing a problem with the processing process. I use a real joint server in a digital hosting package of $ 10 and use cloud service from Amazon s3. The problem is when uploading a video, whatever the size of the video, whether its size is 1 megabyte or 2 Giga. After the upload process, the processing process starts to upload, there is no problem But when the processing process takes a very long time so that I cannot complete it, what is the solution to that, is there a problem for me or is this process normal ?
 I use laravel-ffmpeg and through laravel queue I am cutting the video into several qualities I will attach the code to you below.



public function handle()
{
 //180p
 $lowBitrate1 = (new X264('aac'))->setKiloBitrate(613);
 //270p
 $lowBitrate2 = (new X264('aac'))->setKiloBitrate(906);
 //360p
 $midBitrate1 = (new X264('aac'))->setKiloBitrate(1687);
 //540p
 $midBitrate2 = (new X264('aac'))->setKiloBitrate(2227);
 //720p
 $highBitrate1 = (new X264('aac'))->setKiloBitrate(4300);
 //1080
 $highBitrate2 = (new X264('aac'))->setKiloBitrate(7917);

FFMpeg::fromDisk('s3')
 ->open($this->movie->path)
 ->exportForHLS()
 ->onProgress(function ($percent) {
 $this->movie->update([
 'percent' => $percent
 ]);
 })
 ->setSegmentLength(10)// optional
 ->addFormat($lowBitrate1)

 ->addFormat($highBitrate1)

PHP : Convert file with FFMPEG and upload to S3 using shell_exec() and aws cli tools
18 septembre 2017, par andreaemI need a script that handle the upload of a video file from
dropzone.js
, convert tom4v
then generate 5 thumbnails using the name of file appending-(number)
to each jpg file (eg :file-1.jpg
,file-2.jpg
,file-3.jpg
etc) and finally upload to s3 using shell_script (or maybe if there is a better way to do this).Recap
- Upload file in a temp dir
- Convert file to
.m4v
- Generate 5 thumbnails from video
- Upload the converted video to Amazon S3
- Delete local video file
Here is my code, at the moment I don’t know where the file goes and nothing seems to be uploaded to Amazon S3 (doing the upload in command-line works, so the credentials are ok).
Dropzone.js
$("#dZUpload").dropzone({
url: "/ajax/admin/admin.acceptVideo.php",
maxFilesize: 200,
renameFile: new Date,
acceptedFiles: "video/*",
addRemoveLinks: true,
success: function (file, response) {
var imgName = response; file.previewElement.classList.add("dz-success");
console.log("Successfully uploaded :" + imgName);
$('#form_video').val(file);
},
error: function (file, response) {file.previewElement.classList.add("dz-error");
}
}).autoDiscover = false;
Dropzone.prototype.defaultOptions.dictRemoveFile = "Rimuovi file";
Dropzone.on("addedfile", function(file) {
var cancelLink = Dropzone.createElement('<a>Cancel upload</a>');
file.previewElement.appendChild(cancelLink);
cancelLink.addEventListener("click", function(e) {
e.preventDefault();
myDropzone.cancelUpload(file);
});
});PHP
$target_dir = "/var/www/html/example.com/web/temp/";
$target_file = $target_dir . basename($_FILES["file"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["file"]["tmp_name"]);
if($check !== false) {
echo "File is a video - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 200000000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "mp4" && $imageFileType != "mov" && $imageFileType != "avi" && $imageFileType != "m4v" ) {
echo "Sorry, only MP4 MOV AVI M4V files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {
S3Up(VideoConvert(basename( $_FILES["file"]["name"]),random_int('1','9999')));
echo "The file ". basename( $_FILES["file"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
function VideoConvert($video, $id) {
shell_exec('ffmpeg -i ' . $video . ' /var/www/html/example.com/web/temp/' . $id . '.m4v');
for ($i=0;$i <= 5;$i++) {
shell_exec('ffmpeg -i ' . $video .' -vf "select=gte(n\,' . $i .'00)" -vframes 1 ' .$id . '-' . $i. '.jpg');
}
return '/var/www/html/example.com/web/temp/' . $id . '.m4v';
}
function S3Up($video) {
shell_exec('aws s3 cp ' . $video .' s3://example-video/ --grants read=uri=http://acs.amazonaws.com/groups/global/AllUsers');
sleep(1);
//shell_exec('rm '. $video);
}Here is my error.log line relating to s3 upload :
error.log
example.mp4: No such file or directory

Behavior
At the moment
dropzone.js
stop uploading at 50% if I put a file of 8 MB, php maxUploadSize directive is set to 201M, php upload temp folder is inside the site root directory and permissions set to 7777. File where uploaded if I put a smallest file of 200Kb but don’t convert and make a 0 byte file. -
Find video resolution and video duration of remote mediafile
22 février 2012, par osgxI want to write an program which can find some metainformation of mediafile. I'm interested in popular video formats, such as avi, mkv, mp4, mov (may be other popular too). I want basically to get :
- Video size (720, 1080, 360 etc)
- Total runtime of video (may be not very exact)
- Number of audio streams
- Name of video codec
- Name of audio codec
There is already the mediainfo, but in my program I want to get information about remote file, which may be accessed via ftp, http, samba ; or even torrent (there are some torrent solutions, which allows to read not-yet downloaded file).
MediaInfo library have no support of samba (smb ://) and mkv format (for runtime).
Also, I want to know, how much data should be downloaded to get this information. I want not to download full videofile because I have no enough disk space.
Is this information in the first 1 or 10 or 100 KiloBytes of the file ? Is it at predictable offset if I know the container name and total file size ?
