  25 octobre 2011, par tetue -

  Pourquoi pas, mais ce serait plutôt ’edition’, car il s’agit d’éditer (le descriptif, etc.) et non de publier le site. On peut essayer, mais ça n’est pas choquant que ça reste à sa place habituelle. C’est surtout l’entrée ’Plugins’ qu’il faut déplacer dans ce menu, pour marquer la séparation entre (...)

• FFMPEG - latest build doesn't work, earlier build does

  21 juin 2020, par rossmcm

  I have been using FFMPEG to overlay coloured rectangles on a video. I updated FFMPEG and it no longer works. No error is issued, it just doesn't do the job - the resulting video is the same as the input video. Here's the script :

  


  FFMpeg -y -i Input.mp4 -filter_complex \
  "nullsrc=size=1920x1080,  \
  drawbox=x=200:y=100:w=300:h=150:t=20:c=yellow,  fade=in:st=10:d=1:alpha=1, fade=out:st=20:d=2:alpha=1 [tmp1]; \ 
  nullsrc=size=1920x1080,  \
  drawbox=x=240:y=140:w=300:h=150:t=20:c=red,  fade=in:st=15:d=1:alpha=1, fade=out:st=25:d=2:alpha=1 [tmp2]; \
  [tmp1][tmp2] overlay=0:0:shortest=1[tmp3]; \
  [0:v][tmp3] overlay=0:0:shortest=1" \
  Output.mp4


  


  The output video should be the input video with a yellow rectangle added from T=10 to T=20 and a red rectangle from T=15 to T=25, fading them in and out.

  


  The version that was working (3.4) was one that came with an ImageMagick installation. The version I updated it to was 4.2.3. I tried it on various other builds I had lying around and it only works with 3.4.

  


  It seems unlikely that this is a regression so I haven't submitted a bug report. I figure it's more likely that I'm not doing something correctly and 3.4 is more lenient on its interpretation of my command.

  


  Whatever, I prefer to be working with a current build, so I invite comments on what the reasons might be.

  


  Console dump of 3.4 run

• Custom Build of FFMPEG only for screenshots

  31 août 2020, par Sivakumar

  I have a disk space issues while using static FFMPEG build in my lambda. So can i use Customized FFMPEG build only to take screenshot for my Videos(All Formats Ex : mp4, mov, ...) to JPG. Any suggestions or anyone having reference to get the custom build only for this purpose.
