  • How to get input basename in output ?

    12 août 2023, par becauseim
    @echo off
set source="%1"

for %%a in (*.wav, *.aac, *.mp3,) do (
    ffmpeg -i "%1" -i "%%a" -c:v copy -map 0:v:0 -map 1:a:0 -shortest "%1_123.mov"

  • Converting mkv to mp4 with ffmpeg sometimes loses video

    9 décembre 2019, par RobertW

    How can I create a universal as possible command line to convert mkv to mp4 ?

    I fixed an issue where sometimes I’d lose audio (I think) and now I’m losing video.
    This is the command I currently use (I’ve used a few, including -analyzeduration 1G -probesize 50M but I always end up with broken videos at some point) :

    if [[ $(pgrep -i ffmpeg) ]] ; then
    
  echo "FFMPEG IS ALREADY RUNNING!"
    
else 
    
  echo "Starting mkv to mp4 conversion...";
    
    for i in /var/www/html/uploads/Videos/*/*/*/*.mkv;
    
      do name=$(echo "${i//.mkv/}");
    
      echo "$name";
    
      ffmpeg -n -i "$i" -c copy -c:a aac -movflags +faststart "${name}.mp4"; rm -v -f "${name}.mkv";
    
    done
    
fi

    Output of running that on the specific videos I’m losing picture on :

  • getting video duration with ffmpeg, php function

    17 novembre 2014, par keithp

    I have FFMpeg installed and I know it’s functional, but i’m trying to get the duration time from a flv video through PHP but when I use this code :

    function mbmGetFLVDuration($file)

    /*  
    
* Determine video duration with ffmpeg   
    
* ffmpeg should be installed on your server.  
    
*/  
    

    
//$time = 00:00:00.000 format   
    
$ffmpeg = "../ffmpeg/ffmpeg";
    

    
$time =  exec("$ffmpeg -i $file 2>&1 | grep 'Duration' | cut -d ' ' -f 4 | sed s/,//");   
    

    
$duration = explode(":",$time);   
    
$duration_in_seconds = $duration[0]*3600 + $duration[1]*60+ round($duration[2]);   
    

    
return $duration_in_seconds;  

    and :

    $duration = mbmGetFLVDuration(’http://www.videoaddsite.com/videos/intro.flv’) ;
    echo $duration ;

    I get an output of 220. THe video is 3:40. Can any help me on what i’m doing wrong, or if there’s something else I can use ?
