FFMPEG - Green cast with Splash image in video
30 mai 2020, par rossmcmI'm using FFMPEG to produce a video consisting of a single monchrome JPG image :



ffmpeg -y -loop 1 -framerate 30 -t 5 -i SplashBW.jpg Splash.mp4



There are two issues with the resulting video :



- 

- When viewed with VLC it has a green cast
- When viewed with "Film and TV" (I suspect this is the Windows 10
viewer - the association for MP4 files seems to have been hijacked
on my PC) it has a green cast and a predominant flickering every
0.5 seconds or so.







When viewed with Irfan View it looks fine. I don't know whether the issue is with the original JPG, the FFMPEG command, or the viewers. Naturally, I want it to render properly on all outputs.



The first two links below look fine in my browser (Chrome) when I open them. The third link is a screen recording of what I see when I try to play the video with the
Film and TVapp.

Use ff mpeg inside a loop to create thumbnails
30 avril 2014, par Paul LedgerI have an uploader which I am creating for a site. The uploader is a jquery plugin which I am on creating that allows single of multiple uploads of images or videos.
The uploader works with no problems and ffmpeg does create thumbnails no problem. However I have a max file size of 1GB which I will implement to the total of uploads so that users cannot upload to much in one go. But for testing I haven’t yet so I can test the limits of the uploader capabilities before adding restrictions.
I have 4 videos I am using to test 246mb each. The files upload and move to the folder set on the test server (localhost) but the thumbnails don’t create as the PHP script extends the maximum time limit. The easy option would be to change this in php.ini easily.
The problem is thought the progress bar only tracks the upload not the ffmpeg conversion. Is there a way of tracking this in my progress bar or running this as a background task with multiple video files.
It might be worth mentioning but with smaller videos, under 70mb each there is no problem at all thumbnails are created but still after the progress bar reaches 100%.
If it helps heres the relevant sections of the code. I can add the full source on git if needed. But I do fear that the answer will be no or alter the php.ini file
JQuery/ Ajax :
$.ajax({
url: options.processor,
type: "POST",
data: formdata,
processData: false,
contentType: false,
dataType:"JSON",
beforeSend: init,
error: error,
xhr: function() {
var myXhr = $.ajaxSettings.xhr();
if(myXhr.upload){
myXhr.upload.addEventListener('progress',uploadProgress, false);
}
return myXhr;
},
success: onComplete
});
var uploadProgress = function(e){
if(e.lengthComputable){
if(options.single === true){
$('#'+options.counter).html('File 1 of 1');
}else{
$('#'+options.counter).html('Files '+ item_count +' of ' + item_count + ' uploading');
}
var p = (e.loaded / e.total) * 100;
$('#'+options.progress_text).html(Math.round(p) + '%');
$('#'+options.progress_bar).width(p + '%');
}
}PHP :
if(!empty($_FILES['file'])){
if(!empty($_POST['single'])){
//single file upload
if($_FILES['file']['error'] === 0){
$temp = $_FILES['file']['tmp_name'];
$name = $_FILES['file']['name'];
$ext = explode('.',$name);
$ext = strtolower(end($ext));
$file = md5($temp).time().'.'.$ext;
if(in_array($ext,$allowed) === true && move_uploaded_file($temp,"../uploads/{$file}") === true){
$succedeed[] = array('name' => $name,'file' => $file,'type'=>'image');
}else{
$failed[] = array('name' => $name, 'file' => $file, 'error' => 'File type not allowed');
}
}
}else{
//multiple file upload
foreach($_FILES['file']['name'] as $key => $name){
if($_FILES['file']['error'][$key] === 0){
$temp = $_FILES['file']['tmp_name'][$key];
$ext = explode('.',$name);
$ext = strtolower(end($ext));
$_file = md5($temp).time();
$file = $_file.'.'.$ext;
if(in_array($ext,$allowed) === true && move_uploaded_file($temp,"../uploads/{$file}") === true){
$file_type = explode('/',$_FILES['file']['type'][$key]);
if($file_type[0] === 'image'){
echo 'image';
$succedeed[] = array('name' => $name,'file' => $file, 'type' => 'image');
}else{
$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;
$cmd = "ffmpeg -i $input -an -ss $pos -s $size $output";
shell_exec($cmd);
$succedeed[] = array('name' => $name,'file' => '/thumbs/'.$_file.'.jpg', 'type' => 'video');
}
}else{
$failed[] = array('name' => $name, 'file' => $file, 'error' => 'File type not allowed');
}
}
}
}
}**UPDATE the process of converting the files to thumbnails takes less time if I drop the posotion of where the thumb is taken from ie :
$cmd = "ffmpeg -i $input -an -ss $pos -s $size $output";would become
$cmd = "ffmpeg -i $input -an -ss 3 -s $size $output";I presume this is because ffmpeg plays the video until it gets to that point in the video to take the thumbnail. There for if the video is 5mins and the the thumb is taken at 2.30 then each conversion would take 2 min 30. I think I answered my own question here but take the thumbnail form somewhere between 1 - 5 seconds. Or alternately add a second progress bar into the onComplete handler which would calculate the time this would take and display it to the user.

FFMPEG Add 2 watermarks (txt + png) to a video
21 mai 2020, par razzI'm trying to add 2 watermarks to a video, one should be a .png file and the second some moving/scrolling text.



Png = fixed at right bottom



Text = Moving/scrolling from the top right to the top left. Starting at 50% of total video length (appear at 1:00 if total length is 2:00) and disappearing in 20 seconds.



I already use a command to encode the video and add a logo at the right bottom but having trouble adding scrolling text at the same time.



-i logo.png -filter_complex "overlay=main_w-overlay_w:main_h-overlay_h-4" -keyint_min 20 -vcodec libx264 -c:a copy -b:v 1500k -movflags +faststart
