• 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 !

  lavfi : Always propagate hw_frames_ctx through links
  Also adds a new flag to mark filters which are aware of hwframes and
  
  will perform this task themselves, and marks all appropriate filters
  
  with this flag.
  This is required to allow software-mapped hardware frames to work,
  
  because we need to have the frames context available for any later
  
  mapping operation in the filter graph.
  The output from the filter graph should only propagate further to an
  
  encoder if the hardware format actually matches the visible format
  
  (mapped frames are valid here and have an hw_frames_ctx, but this
  
  should not be given to the encoder as its hardware context).

• FFMPeg stuck while processing a video

  15 juin 2017, par Muhammad Umar

  I am trying to add slow motion to an FFMPEG video in android

  On my terminal original query i use is

  ffmpeg -i soon.mp4 -filter_complex "[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]" -map "[v]" -map "[a]" output.mp4

  Here is my code in android,

      String cmd = "/data/data/PACKAGE_NAME/files/ffmpeg -i "+ videoFileName +" -filter_complex [0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a] -map [v] -map [a] " + file.getAbsolutePath();

  In Android , i have only removed quotation marks since ffmpeg is not recognising these.

  When i exceute FFMPEG,
  following happens
