Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.

Use ffmpeg to stream live content to azure media services
9 juin 2016, par DadicoolI’ve been trying to stream content to azure media services using ffmpeg as it’s one of the options described here : http://azure.microsoft.com/blog/2014/09/18/azure-media-services-rtmp-support-and-live-encoders/
My command is :
ffmpeg -v verbose -i 300.mp4 -strict -2 -c:a aac -b:a 128k -ar 44100 -r 30 -g 60 -keyint_min 60 -b:v 400000 -c:v libx264 -preset medium -bufsize 400k -maxrate 400k -f flv rtmp://nessma-****.channel.mediaservices.windows.net:1935/live/584c99f5c47f424d9e83ac95364331e7
I have made sure that the streaming endpoint has one active streaming unit, I also made sure that the channel is actually Ready and I even get it to start streaming (which makes a PublishURL available).
When I execute the ffmpeg command to start streaming, I keep getting the following error :

checkasm : updated tests for sw_scale
13 août 2022, par Swinney, Jonathancheckasm : updated tests for sw_scale
Change the reference to exactly match the C reference in swscale,
instead of exactly matching the x86 SIMD implementations (which
differs slightly). Test with and without SWS_ACCURATE_RND - if this
flag isn't set, the output must match the C reference exactly,
otherwise it is allowed to be off by 2.Mark a couple x86 functions as unavailable when SWS_ACCURATE_RND
is set - apparently this discrepancy hasn't been noticed in other
exact tests before.Add a test for yuv2plane1.

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.
