Show Filename in Video ffmpeg batch script
19 mars 2019, par Oli ShingfieldI have a folder with around 10 different mov files. I would like to add the filename as text on each of the videos using ffmpeg in a bat file. Could someone help me achieve this please ?
EDIT :
I have tried using
@ECHO OFF&Setlocal EnableDelayedExpansion
Set INPUT=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3
Set OUTPUT=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3
for %%a in ("%INPUT%\*.*") DO (
set "filename=%%~na"
ffmpeg -i "%%a" -vf "drawtext=text=!fileName:.= !:x=105:y=120:fontfile=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3\\impact.ttf:fontsize=25:fontcolor=white" -b:v 1M -r 60 -b:a 320k -ar 48000 -crf 17 "%%~na.mov"
)`But it gives me the error :
Cannot find a valid font for the family Sans
[AVFilterGraph @ 0000026eb75a9f40] Error initializing filter 'drawtext' with args 'text=FileName1'

upload.php


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);

}

 unlink($imagename);
}

$result = array();

 <button type="button" class="btn btn-link remove_image">Remove</button>
 ';
 }
 }
}
$output .= '</div>';
echo $output;

?>


EDIT :
I put the example on an Array, I don't want it, I just want it to show the downloaded video I just uploaded as a result.


EDIT 2 :
There are some who say type $location and it displays the downloaded file, but this does not work !!!
I just tried more than once and with several uses, there is no display where the text is empty


This is an example of that


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);
 $locationStr = str_replace(" ","\ ",$location);
 $cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
 echo shell_exec($cmd);
}

if(isset($_POST["name"]))
{
 $filename = $folder_name.$_POST["name"];
 $imagename = $thumb_name.$_POST["name"].$imageext;
 unlink($filename);
 unlink($imagename);
}


$output .= 'Successfly file is "'.$location.'"';
echo $output;

?>


Result : Successfly file is ""
no name file :(


EDIT 3 :


this code upload.php
functions not working


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);
 $locationStr = str_replace(" ","\ ",$location);
 $cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
 echo shell_exec($cmd);
}


echo "The file " . $location . " has been uploaded";
// not working
echo "<br />";
echo "The file " . $upload . " has been uploaded";
// not working
echo "<br />";
echo "The file " . $uploadStr . " has been uploaded";
// not working
echo "<br />";
echo "The file " . $locationStr . " has been uploaded";
// not working

?>

About the developer solution Markus AO


I did the experiment and it is quite good, but dropzone is still missing, because I will upload a large video and the normal upload compresses the video before uploading, here is a picture from my mobile while uploading, but this does not happen with dropzone



I want to implement this in dropzone as well, because this library does not compress the video, but upload it in full size.


Thank you bro.

Hide ffplay window and just show input video [closed]
5 mai 2023, par Scott WilkersonI'm using FFMPEG/FFPLAY to display video on a monitor from a Decklink card. After much research I finally found a good command to get the video displayed correctly, and at a specific location in the monitor with no border :


ffplay -f dshow -video_size 1280x720 -left 631 -top 19 -rtbufsize 702000k -framerate 59.94 -i video="Decklink Video Capture":audio="Decklink Audio Capture" -threads 2 -noborder


The problem is I need to ONLY display the borderless input video. NOT ffplay running. I figured out I could use -nostats to get rid of the video statistics, but not the command prompt window.


-nostdin DOESN'T WORK
-nodisp HIDES THE INPUT VIDEO, not the command prompt window.


Thanks in advance !
