• FFmpeg : Green images from TS file

  5 septembre 2017, par Tatsiana

  I use ffmpeg to generate images from a TS file and at some places it generates green images. I checked a couple of ffmpeg versions. The issue reproduces on
  3.3.3, 2.8.11, 2.7.7, but doesn’t on 2.6.9.
  What might be the reason ?

  For example, the output of 2.8.11 :

      $ ffmpeg -ss 00:42:20 -i video.ts -frames:v 1 out_42_20.jpg -loglevel debug

• ffmpeg concat with video using image background

  16 janvier 2018, par ant-C

  Ffmpeg does not concat the media files correctly using various testing. One of the videos is a .mp4 (h264 codec) video generated previously using a .mp3 and a jpeg background. I’ve tried testing with various flags, closest I’ve gotten is below for the final output.

  My main issue is the final video with the current test, the audio is about 3 seconds delayed once the two videos are stitched together.

  Here are all the files I’m using :

  Input Files :

  • audio.mp3

  • image.jpg

  • main_video_raw.mp4

  Output Files :

  • new_image_video_raw.mp4

  • new_image_video.mp4

  • main_video.mp4

  • final_output_video.mp4

• 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"
