• PHP code not proceeding to the line after exec ffmpeg

  5 avril 2014, par Sel

  I have this PHP snippet that I call through curl, in order to perform an ffmpeg encoding. I also have another line afterwards that marks this as having been done, using a database. I want this to trigger after the exec finished, which would imply that the file has finished encoding. However, the database is never actually changed (works if I try commenting out the exec) and I can't get a good gauge of when the file is done encoding. The database only changes when you run ANOTHER request on top of this one. Code below.

  $ID=$_POST['ID'];
  
  
  
  exec("/usr/local/bin/ffmpeg -i stockvideos/Intro2.m2v -f image2 -loop 1 -r 24 -i temppics/Intro2pic".$ID.".png -filter_complex \
  
  '[1:v]fade=in:st=0:d=1:alpha=1,fade=out:st=3:d=1:alpha=1[2wm];
  
  [0:v][wm]overlay=10:10[outv]' \
  
  -map [outv] -q 0 tempvideos/Intro2-".$ID.".m2v  >> 1.log 2>&1");
  
  
  
  $query_CreditVideoDone  =sprintf("Update Messages SET CreditTitlesDone=%s WHERE ID=%s", GetSQLValueString(1, "boolean"),GetSQLValueString($ID, "text"));
  
  
  
  $result = mysql_query($query_CreditVideoDone, $MMixer) or die(mysql_error());

  UPDATE : When I check the log (>2), it seems FFMPEG continues running even after the process is finished.

  And so on until it times out on the server. Any idea why this happens ? It seems to prevent execution from anything after it. Redirecting to dev/null doesn't help either - there is no error output of course but the process is still hanging the same way.

  Any help would be appreciated. Thanks !

  Thanks !

• Rotate video, output maximum 1920 x 1080 pixels

  9 avril 2014, par Fabien Biller

  I used

  ffmpeg.exe -ss 310 -i "H:\_REC\100MEDIA\someavi.AVI" -ss 0 -t 14 -vf "rotate='54*PI/180:ow=hypot(iw,ih):oh=ow'" -vf scale=1920:1080 "H:\_REC\100MEDIA\somemp4.mp4"

  which should rotate the video(currently 1920 x 1080, MJPEG, 30fps) around 54° and fit it into 1920 x 1080 Pixels.

  What it does is, it ignores the -vf "rotate='54*PI/180:ow=hypot(iw,ih):oh=ow'" -vf scale=1920:1080 and returns the snippet.

  What to change ?

  PS : ffmpeg version N-59696-gc0a33c4
