  • How to overlay 2 videos at different time over another video in single ffmpeg command ?

    17 mars 2018, par Qandeel Abbasi

    Using ffmpeg command line I want to overlay 2 different videos on top of another (main video) at different time for different duration. I have successfully overlayed 1 video over the main video at specific time and for specific duration using following command :

    ffmpeg -i main.mp4 -i first.mp4 \
    
-filter_complex "[1:v]setpts=PTS-32/TB[a]; \
    
                 [0:v][a]overlay=enable=gte(t\,5):eof_action=pass[out]; \
    
                 [1] scale=480:270 [over]; [0][over] overlay=400:400" \
    
-map [out] -map 0:a \
    
-c:v libx264 -crf 18 -pix_fmt yuv420p \
    
-c:a copy \
    
output.mp4

    How can i modify the same command to apply the same operations on two secondary videos at the same time ?

  • 2>&1 and log file at the same time

    14 mai 2018, par Bruno Andrade

    I’m using this code to run ffmpeg and return when it succeeded or failed using 2> & 1 and $var. The problem is that I would also like to generate a log.txt with the current ffmpeg process. I know it does using 2> log.txt but how do I use both options at the same time ?

    <?php
    
$ffmpeg = '"D:\FFMPEG\bin\ffmpeg.exe"' . " -loglevel verbose -n -i https://URLVIDEO -map p:0 -acodec copy -bsf:a aac_adtstoasc -vcodec copy video.mp4 2>&1";
    

    
    exec($ffmpeg, $output, $var);
    

    
    if($var){
    
       echo 'error';
    
    }else{
    

    
      echo 'success';
    

    
    }
    
?>

  • Align media file size with exFAT cluster size

    2 avril 2021, par Crissov

    Some multimedia container formats with embedded metadata tags (e.g. ID3v2 for MP3) support to allocate some free space inside the file to improve editing speeds for metadata tag updates, because not the whole file needs to be rewritten to disk for minor changes. In MOV and MP4 files, the boxes / atoms free and skip are used for this, as far as I know.

    


    In order to use disk space efficiently, how can I use FFmpeg, MP4Box or some other commonly available software to increase the allocated free space within dozens of 100+ MB video files in a way that the resulting total file sizes are exact multiples of the partition’s allocation unit size, e.g. 128 KiB by default for a 1-terabyte exFAT drive ?
