• How to merge list of videos with frame specifiec order using ffmpeg ?

  9 décembre 2015, par Il'ya Zhenin

  I have a list of files :

  even_0.avi
  
  odd_0.avi
  
  even_1.avi
  
  odd_1.avi
  
  ...
  
  even_n.avi
  
  odd_n.avi

  And I want to merge them in a single video file in such a way, that zero frame would be taken from even_0.avi, first frame from odd_0.avi, second - from even_0.avi and so on.

  And if all frames in even_0.avi are taken, then next frame we will take from even_1.avi, next from odd_0.avi, next again from even_1.avi. Basically, when one video ends, we just start taking frames from the next video with prefix "even_" or "odd_".

  I just started using ffmpeg, know, how to simply merge videos, change resolution, fps and so on, but this is beyond my power, so, please, help.

• FFMPEG RGB Lossless conversion video

  29 août 2017, par DCDCDC

  I have been experiencing difficulty in finding many answers with FFMPEG documentation, forums and here.
  What I am trying to do is a compress a screen capture video but with just RGB data.
  The steps I am currently taking are ;

  ffmpeg -f avfoundation -pix_fmt 0rgb -r "30" -i "1" -vcodec libx264rgb -pix_fmt rgb24 -crf 0 -t 25 -q 0 -y ~/Desktop/RGB.mkv

  This captures the screen on my mac. To the best of my knowledge, this creates a lossless file and I have compared screen shots that confirm this.
  The next step is where I think I have an issue.
  Because I want to run the compression on raw RGB data I need to convert the MKV to an RGB file ;

  But here I have pixel variance. My guess is there is a RGB-YUV-RGB conversion happening somewhere but I am not smart enough to work out where.
  If any of you can help I would forever grateful.

  Here is a picture of the two stills side by side that shows the differences ;

  If you need anything more I can post it also.

• Is there a way to speed up the FFmpeg command '-filter_complex' ?

  31 août 2017, par Emma

  When using ffmpeg to re-encode videos, this is pretty fast. But when using the -filter_complex command the process slows down to real time. Is this process bound to the CPU or GPU ? Does anyone know if there is any way to speed this up using the GPU ?

  The full call is the following :

  ffmpeg.exe
  
  -i video_0_0.mp4 -i video_0_1.mp4 -i video_0_2.mp4 -i video_0_3.mp4 
  
  -filter_complex 
  
      "color=c=black:size=1920x1080 [base]; 
  
      [0:v] setpts=PTS-STARTPTS, scale=960x540 [upperleft]; 
  
      [1:v] setpts=PTS-STARTPTS, scale=960x540 [upperright]; 
  
      [2:v] setpts=PTS-STARTPTS, scale=960x540 [lowerleft]; 
  
      [3:v] setpts=PTS-STARTPTS, scale=960x540 [lowerright]; 
  
      [base][upperleft] overlay=shortest=1 [tmp1]; 
  
      [tmp1][upperright] overlay=shortest=1:x=960 [tmp2]; 
  
      [tmp2][lowerleft] overlay=shortest=1:y=540 [tmp3]; 
  
      [tmp3][lowerright] overlay=shortest=1:x=960:y=540" 
  
  -q 4 -y
  
  "test.mp4"

  output of the command :

  ffmpeg.exe -i video_0_0.mp4 -i video_0_1.mp4 -i video_0_2.mp4 -i video_0_3.mp4 -filter_complex "color=c=black:size=1920x1080 [base]; [0:v] setpts=PTS-STARTPTS, scale=960x540 [upperleft]; [1:v] setpts=PTS-STARTPTS, scale=960x540 [upperright]; [2:v] setpts=PTS-STARTPTS, scale=960x540 [lowerleft]; [3:v] setpts=PTS-STARTPTS, scale=960x540 [lowerright]; [base][upperleft] overlay=shortest=1 [tmp1]; [tmp1][upperright] overlay=shortest=1:x=960 [tmp2]; [tmp2][lowerleft] overlay=shortest=1:y=540 [tmp3]; [tmp3][lowerright] overlay=shortest=1:x=960:y=540" -q 4 -y "test.mp4"
