  • Extracting aspect ratio from ffprobe

    29 décembre 2020, par Linx

    I'm using ffprobe to determine a video's properties and assign them as variables in a bash script for batch encoding with ffmpeg, like so :

    


    eval $(ffprobe -v quiet -show_format -of flat=s=_ -show_entries 
        stream=height,width,duration,display_aspect_ratio "$f");
        width=${streams_stream_0_width};
        height=${streams_stream_0_height};
        aspect=${streams_stream_0_display_aspect_ratio};
    
    echo -e "Height/Width = $height/$width, Aspect = $aspect\n";


    


    That returns "Height/Width = 480/720, Aspect = 4:3" exactly like it should. But I need to insert the variable into my encode command as 4/3 and not 4:3. I'm not very good with bash scripting and I've searched for a solution, but I'm not even sure what you call what I'm trying to do, so I'm sure I've done the wrong search terms. How can I convert this ratio into a fraction to insert into a ffmpeg command ?

    


  • Images to video in PHP with FFmpeg

    14 mars 2013, par Boris Kremenovic

    I got a terrible problem. I've been searching, and google-ing my whole day and can't find the answer to this problem..

    I am trying to convert 5 pictures to video using FFmpeg in PHP. I have FFmpeg extension installed in my php.ini.

    Trying running this command :

    <?php
    
exec("ffmpeg -r 25 -qscale 2 -i %05d.jpg output.mp4");
    
?>

    but it gives me a blank page with no errors or something. Can anybody help me ?

  • FFMPEG GOP Extraction

    29 mars 2015, par user3601375

    I have an MPEG -4 video and I would like to extract a one GOP (Group of pictures ) at a time to BMPs (using FFMPEG and c++ (code block) ) rather than the whole video in one go, since now all my code writing is stuck there I use to sketch everything in my mind then program and I can’t imagine how to do this, I searched the net for something like that but of no use.. any command line or any library used to do that (I have no full experience on FFMPEG I have read the documentation but that thing was not there). I will appreciate any kind help and thanks for reading y post.
