De l’upload à la vidéo finale [version standalone]
31 janvier 2010, parLe chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
Upload et récupération d’informations de la vidéo source
Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

PHP Foreach query only displays final result for slideshow ?
22 janvier 2023, par ShaneRibzUsing a query I pull the most liked video's on a localhosted stream webpage, and use FFMPEG to create a thumbnail if one isnt already existing and the video length.


The query succesfully pulls the 4 most liked video's and displays them in a carousel. FFMPEG succesfully creates each thumbnail, and gets the length of each video.


Somewhere, for whatever reason I cant figure out, only the final slide in the carousel displays the thumbnail as its background.


Sorry if my code is messy, I'm learning how to better optimize.


<?php
 $sql = "use info";
 $pdo->exec($sql);
 $stmt = $pdo->query("SELECT * FROM `files` ORDER BY `like` DESC LIMIT 4");
 $filelist = $stmt->fetchAll(PDO::FETCH_ASSOC);
 $h = 0;
 foreach ($filelist as $row) {
 if ($h < 25){
 $h++;
 
 $name = $row['name'];
 $location = $row['location'];
 $type = $row['type'];
 $uploadby = $row['uploadby'];
 $like = $row['like'];
 $id = $row['fileid'];
 $cat1 = $row['Cat1'];
 $cat2 = $row['Cat2'];
 
 $ffmpeg = 'F:\\xampp\ffmpeg.exe'; 
 $location = str_replace("/","\\", $location);
 $video = 'F:\xampp\htdocs\\'. $location; 
 $bigloc = "F:\\xampp\htdocs\\thumb\big";
 $smallloc = "F:\\xampp\htdocs\\thumb\small";
 $image = $bigloc . "\\" . $name . ".jpg"; 
 $image2 = $smallloc . "\\" . $name. ".jpg"; 
 
 if (file_exists($image) and (file_exists($image2))) {
 
 } else {
 echo $image . " does not exist";
 $cmd="$ffmpeg -ss 00:25:00 -i ". "\"" . $video . "\"". " -s 1920x540 -vframes 1 ". "\"" .$image. "\"" . " -report"; 
 $cmd2="$ffmpeg -ss 00:25:00 -i ". "\"" . $video . "\""." -s 270x370 -vframes 1 ". "\"" .$image2. "\"";
 echo "<br />". $cmd . "<br />".$cmd2."<br />";
 exec($cmd);
 exec($cmd2);
 }
 
 $file = "\"". $video. "\"";
 $result = shell_exec('ffmpeg -i ' . escapeshellcmd($file) . ' 2>&1');
 preg_match('/(?<=Duration: )(\d{2}:\d{2}:\d{2})\.\d{2}/', $result, $match);
 $time = $match[1];
 $image = "thumb/big/" . $name . ".jpg"; 
 $image2 = "thumb/small/" . $name. ".jpg";

 ?>

 <div class="single-hero-slider-wrap single-animation-wrap slider-height-hm4 bg-image-hm4 slider-bg-color-black d-flex align-items-center slider-bg-position-1 bg-black" style="&lt;?php echo &#x27;background-image:url(&#x27;. $image.&#x27;);&#x27;;?>">
 <div class="slider-content-hm4 slider-animated">
 <h1 class="title animated"><?php echo $name;?></h1>
 <div class="sub-title-time-wrap">
 <span class="sub-title animated"><?php if ($cat2 != ""){ echo $cat1 .", ". $cat2; }else{ echo $cat1;}?></span>
 <span class="time animated"><?php echo $time;?></span>
 </div>
 <div class="slider-button">
 <a href="http://stackoverflow.com/feeds/tag/movie-details.html" class="btn-style-hm4 animated">Watch Now</a>
 </div>
 </div>
 </div>

 <?php 
 }
 } 
 ?>


When inspecting the source code on my web browser ;
"
style="<?php echo 'background-image:url('. $image.');';?>"", this will only appear on the final slide. The first 3 slides wont have "background-image" at all.

I feel as though I'm making a silly mistake and just cant see it.


EDIT
I should note, the "$name" and "$time" for each displays properly, its just the background-image that does not.


EDIT 2
Here is the source code :


<div class="single-hero-slider-wrap single-animation-wrap slider-height-hm4 bg-image-hm4 slider-bg-color-black d-flex align-items-center slider-bg-position-1 bg-black" style="background-image: url(&#x27;thumb/big/Alita Battle Angel.png&#x27;);">
</div>

The "background-image" shows in source, but during inspect element it does not. No errors populate either.

ffmpeg final video no audio when combining images + video clips that have sound
14 juillet 2022, par Cabdi CilmI am using pytube to merge some downloaded clips and it downloads the clips with audio in the final folder, however when it combines the 2 clips together, there is no audio.


config.IMG_WIDTH = None
final_clip = concatenate(clips, method="compose")
ffmpeg_write_video(
 final_clip,
 os.path.join(os.path.dirname(__file__), "final", "final_vid.mp4"),
 fps=60,
 codec="h264_amf",
 bitrate="8000k",

FFMPEG - 2-pass video conversion final file size is larger than expected
14 juin 2022, par Kevin KorbWe are converting files and the target filesize is important. For one version of the video it can not be above 750KB.


We are using the 2-pass encoding and specifying the target audio bitrate and target video bitrate, however the longer the duration of the video, the larger the file becomes and exceeds our 750KB target.




For example, our file is 53.3 seconds, we know our final target of
750KB. We like our audio at 48kbps (mono).


So we calculate our target (total) bitrate at : 750*8/53.3 = 112.57
total kbps Audio bitrate = 48kbps Video bitrate = 112-48 = 64kbps
video


We would expect the file produced to be 746.2KB. (112*53.3 / 8)


The file produced is 850k(ish).




Is there something that takes up space in the file that isn't video or audio that we need to take into consideration ?
