• Multiply blend mode using FFMPEG adds green overlay

  25 mars 2014, par Barto

  I'm currently working on a project which needs video editing.
  Here for I'm using ffmpeg, which is working pretty well, except for 1 filter.
  Every video should get an overlay with the Photoshop multiply blend mode.
  I'm using the ffmpeg blend mode, but unfortunately the video gets a green overlay as you can see in the screenshots.

  Original Image
  

  Edited with ffmpeg

  What I'm trying to achieve
  

  Does this has something to do with the mode I'm working in ?
  Below is my current code
  

  #!/bin/bash
  
  vagrant ssh -c "./ffmpeg \
  
  -i /vagrant/public/uploads/video/bw_RzWecVH02p.avi -i /vagrant/public/img/red_ellipse.png \
  
  -filter_complex "blend=all_mode='multiply'" \
  
  /vagrant/public/uploads/video/overlay_RzWecVH02p.mp4"

  Here is my ffmpeg output

• Problems transcoding GoToMeeting output using FFmpeg

  20 avril 2014, par user3466413

  I’m having a nightmare of a time transcoding output from GoToMeeting, recorded using the latest OS X version, to something web-playable. No matter what settings I use, I end up with time syncing problems, at least with this particular recording.

  The .mov file looks like this. Note that it’s variable framerate, and because it’s mostly just a screencast of a PowerPoint presentation with occasional mouse movement, the output should be VFR too to produce a small file yet still preserve occasional motion.

  $ ffmpeg -i original.mov

  The .mov file (which I unfortunately cannot publicly post) plays back properly in any application I use : VLC, Media Player Classic, and QuickTime. However, playing the transcoded output always exhibits the following symptoms :

  • Audio out of sync with what the video is showing, sometimes to the order of minutes off towards the end of this three hour recording
  • In the case of Media Player Classic, clicking a spot on the timeline actually moves the playhead to a spot on the timeline near where I clicked, but not directly on it.

  There are the arguments I’m using for a .mp4 encoding that is playable in all browsers that support H.264. Note that this is on Windows but Linux exhibits the same problems.

  ffmpeg.exe -y -i original.mov -i watermark.png -filter_complex "[0:v] crop=1184:720:178:6,scale=1184:720,setsar=1/1; [0:v][1:v] overlay=1242:648 [0:v]" -vcodec libx264 -acodec libvo_aacenc -q:a 80 -crf 30 -ac 1 -ar 16000 -strict -2 -profile:v baseline -level 3 outout.mkv

  The arguments, other than those that are self-explanatory or trivial :

  • -filter_complex : Crop excess letterboxing/pillarboxing from the video and set the aspect ratio to 1:1 for square pixels (something Safari needed), then overlay a watermark from a PNG and resize the output to 720p
  • -crf 30 : encode the video at constant quality, variable bitrate
  • -ac 1 -ar 16000 : encode with mono audio at 16 KHz
  • -strict -2 -profile:v baseline -level 3 : encode using FFmpeg’s "experimental" H.264 encoder using the Baseline level 3 profile for web compatibility

  Note that yes, this goes to an MKV container initially because, for some reason, encoding directly to a .mp4 container hangs FFmpeg. I then use -acodec copy -vcodec copy to copy the audio and video streams directly into a .mp4 container. Finally I pass the output through MP4Box to interleave it so it can be progressively downloaded.

  When transcoding, FFmpeg does drop frames, which I suspect is related to the problem, with output like this :

  FFmpeg: frame=  232 fps= 26 q=24.0 size=    5983kB time=00:32:44.57 bitrate=  24.9kbits/s dup=0 drop=1487

  When I then later attempt to mux it into the .mp4 container from this temporary .mkv container, I get a flood of warnings like this :

  [mp4 @ 0297cd00] Non-monotonous DTS in output stream 0:0; previous: 6341306, current: 6007024; changing to 6341307. This may result in incorrect timestamps in the output file.

  Now I wouldn’t be surprised if there is indeed some problem with the source file. However, if so, I need to definitively prove just how it’s broken.

  Any thoughts ?

• ffmpeg failing to convert

  27 mars 2014, par Daniel7912

  I am using the following command to convert a mp4 on my server to webm as part of a Node.js script.

  var command = execSync('ffmpeg -i '+video+' -vpre libvpx-720p -cpu-used -5 -deadline realtime -b 3900k -an -f webm -y '+saveTo);

  When running the command in a regular terminal, it works fine. However, when running it as above using the execSync() node package, I get the following console output.
