    On playing the input.mp4 with exo player i was able to see the injected ttml subtitle.

    


    Now im trying to conver this mp4 file in to hls using the following command

    


    ffmpeg -i input.mp4 -profile:v baseline -level 3.0 -s 640x360 -start_number 0 -hls_time 10 -hls_list_size 0 -f hls index.m3u8

  • FFMPEG fade in/out expressed in milliseconds

    22 juillet 2020, par orestino

    I working on a programmatic sketch to cut, crop and fade in/out audio from a single input video file.
Everything works pretty well except for the audio fade in fade out.

    


    Everything work fine if I set a fade in and fade out time of 1 (or more) seconds. Here's my command :

    


    ffmpeg -ss 0:1:11.10 -i INPUT_FILE.mp4 -filter:a afade=t=in:st=0:d=1.0,afade=t=out:st=55.867:d=1.0 -filter:v crop=720:720:138:0 -to 0:0:56.86 OUTPUT_FILE.mp4


    


    Fade filter stop working if I set time less than 1 secs (say 100ms like the following example).

    


    ffmpeg -ss 0:1:11.10 -i INPUT_FILE.mp4 -filter:a afade=t=in:st=0:d=0.1,afade=t=out:st=56.767:d=0.1 -filter:v crop=720:720:138:0 -to 0:0:56.86 OUTPUT_FILE.mov


    


    I mean, ffmpeg is not complaining about any error but the output video file simply has no fade in or fade out.

    


    Why ?
What I'm doing wrong ?

    


    Thank you so much for your support

    


    Edit 22/07/2020 :
here's the output from the second command :

  • FFmpeg (Thumbnail from video) works in command line, but not in PHP script

    2 mars 2017, par Jun Kim

    I looked at the similar questions, and the solutions there do not work in my case. Anyone has any idea ? I am trying to capture a thumbnail from a given video file.

    Later, my goal is to capture a thumbnail from live streaming video file.

    Below is my current set up.

    Linux Ubuntu 16.04

    PHP version 7.0

    Nginx Version 1.10.3

    FFmpeg Version FFmpeg 2.8.11

    I installed FFmpeg through below commands in my Ubuntu server.

    apt-get update
    
apt-get install ffmpeg

    When I type the below command line in the terminal, it does the conversion fine.

    ffmpeg -i /etc/nginx/html/test.mp4 -ss 00:00:01 -vframes 1 -vf scale=240:120 /etc/nginx/html/Share/ffmpeg/thumbnails/test.png;

    In order to use it in php file, I confirmed the location of ffmpeg binaries by I typing in the terminal, which ffmpeg, and it returns /usr/bin/ffmpeg

    I also gave permission to the directory by using chmod 755 command line.

    Here is what I have in my ffmpeg.php file.
    I included the full path to my ffmpeg as you can see.

    <?php
    
header("Content-Type: text/html;charset=UTF-8");
    

    
$ffmpeg = "/usr/bin/ffmpeg";
    
$videoFile="/etc/nginx/html/test.mp4";
    
$thumbnail= "/etc/nginx/html/Share/ffmpeg/thumbnails/thumbnail1.jpg";
    

    
$cmd = "$ffmpeg -i $videoFile -ss 00:00:01 -vframes 1 -vf scale=240:120 $thumbnail 2>&1 &";
    

    
$output = shell_exec($cmd);
    
echo "<pre>".$output."</pre>";
    
?>

    This returns the message like below.
