• Video frame difference with FFMPEG

  27 décembre 2015, par StepTNT

  I need to compute the frame differences between a source video and a compressed one.
  For now I’m using OpenCV with Java, by extracting each frame and doing a simple difference, but it’s quite slow (working a 0.5 fps, meaning that a 500 frames video will take more than 15 mins) so I was thinking to move to FFMPEG.

  FFMPEG feels a lot faster (everything’s done under 1 minute) but it has one big issue that makes the results useless : when compressing the source file, done with FFMPEG too, an extra gray frame is added at the beginning and this fakes the results because different frames are compared.

  This is what I’m doing now (knowing that the extra frame messes it all) :

  ffmpeg -y -i src.avi -i compressed.avi -filter_complex "blend=all_mode=difference,hue=s=0" -c:v libx264 -crf 18 -c:a copy difference.avi

  To fix the frame issue I was trying to remove the first frame by re-encoding the compressed video with this command

  ffmpeg -y -ss 0.02 -i compressed.mpg -an -f mpeg2video compressed-cut.mpg"

  (Note that -ss is 0.02 because it’s a 50 fps video, so I did 1/FPS as suggested here)

  But I get this response

  Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

  So, finally, the question is : since extracting all the frames and then compute differences with OpenCV is really slow, how can I use FFMPEG to produce a video containing the difference between two sources while keeping in mind that one of them has an extra frame at the beginning ?

  EDIT : I wanted to avoid posting endless console outputs but since you asked for it, here we go.

  The second command made everything work while the second one in the first part didn’t (the one with the -ss option), so I could be quite happy about it but I’m not that sure if FFMPEG duplicates the first frame for every video or if it’s just related to the one I’m using now, so it could be better to start off with a compressed video that has the same frame count of the original one.

  So let’s get to one final question : why does FFMPEG add a duplicated first frame at the beginning of the compressed video and how can I avoid that ?

• ffmpeg seek calculating wrong byte range ?

  17 décembre 2015, par user4455

  I’m running into an issue while trying to extract thumbnails from a movie file at a specific timestamp. Generally I’ve had no issues with this, but I’ve come across a set of movie files that are getting an error about the byte range requested (416 Requested Range Not Satisfiable).

  The odd thing is that the server is correctly returning the content length in the partial content request, yet when it requests the movie file it requests a length that exceeds that.

  This is a bit over my head, so I’m not sure what could be happening here. Any insight would be great.

  The Command :

  /usr/bin/ffmpeg -y -ss 1400 -i 'https://s3-us-west-2.amazonaws.com/my-bucket/mymoviefile.mp4' -qscale:v 2 -f image2 -vframes 1 -filter:v 'scale=192:108' -loglevel debug /data/www/storage/test.jpg 2>&1

  The Error :

  [https @ 0x22e1e00] header='HTTP/1.1 416 Requested Range Not Satisfiable'
  
  [https @ 0x22e1e00] http_code=416
