• 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"
  )


  



  I get DJI_0002.MOV_123.mov, but I need to get DJI_0002_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 ?
