• Anomalie #4830 : extraire_date extravagant

  6 juillet 2021

  Pourquoi pas. Je te propose (ou quelqu’un) de faire une PR pour ça.
  Il faudrait ajouter en même temps des tests unitaires parce que bon.
  Ci dessous un code valide qui fait la demande.

  Ce qui me gène tout de même c’est le [^0-9]* dans la regex (déjà présente dans l’ancienne fonction) qui du coup peut chercher une date coupée dans un grand texte…
  Tel que : "En 2012 à l’orée du bois se trouvait 10 chevaux et 4 biches.", qui sort la date "2012-10-04" (ou 2012-10-01 avant cette proposition).
  Donc l’usage est possiblement assez limité de cette fonction si laissée telle quelle.

  <span class="CodeRay">
  <span class="comment">/**

• Failed to run the ffmpeg binary : The process "ffmpeg exceeded the timeout of 60 seconds

  6 janvier 2024, par Sufian The Geek

  I am using FSPOSTER wordpress plugin to share videos on instagram as a reels and story. I have installed wordpress on amazon aws ec2 t2.micro. FsPoster required FFmpeg plugin to work with the videos.

  


  Whenever I share the video, I get error after 60 seconds. There are some videos that are easily getting shared as a reel and story. I looked into the plugin code and changed every single timeout function value to 300 seconds including php.ini file. There are some libraries like symfony in the plugin, I also changed the timeout 60 sec to 300 seconds. Restarted the server and all but still getting the error.

  


  


  Failed to run the ffmpeg binary : The process "'ffmpeg' -v error -y -i '/opt/bitnami/wordpress/wp-content/uploads/2024/01/videoWater-First-18.mp4' -vf 'crop=w=1280:h=720:x=0:y=0' -metadata:s:v rotate="" -f mp4 -c:v libx264 -preset fast -crf 24 -strict -2 -c:a aac -b:a 96k '/tmp/fs_65994ac0ddf8b.mp4'" exceeded the timeout of 60 seconds.

  


  


  I am using bitnami wordpress on ec3 aws t2.micro that has 1 vcpu and 1 GB ram. I also switched to 2 vcpu and 8 gb ram but still this timeout issue.

  


• avcodec/proresenc : fix alpha plane encoding bitstream

  26 décembre 2023, par Clément Bœsch

  avcodec/proresenc : fix alpha plane encoding bitstream
  These functions encode a slice of alpha (1 to 8 macroblocks) which are
  
  expected to be encoded as a repeated sequence of "[diff][run-1]", where
  
  diff is the running difference of the alpha value and run is how many
  
  times that value is expected to be duplicated (within the limit of a
  
  grand total of 2048 unpacked samples, corresponding to a slice of 8 MB).
  Even when run==0 (the run variable semantic is actually "run minus 1"),
  
  there is always a diff previously encoded that needs a counter of at
  
  least 1. This means we need to call put_alpha_run() unconditionally at
  
  the end of the bitstream to account for the last running diff.
  This commit fixes glitchy playbacks on QuickTime with M2 and M3 hardware
  
  (but not M1 for some mysterious reason) with files generated with
  
  commands such as :
    ffmpeg -f lavfi -i testsrc2=d=5:s=912x320,chromakey -c:v prores_aw -profile:v 4    -y aw.mov
  
    ffmpeg -f lavfi -i testsrc2=d=5:s=912x320,chromakey -c:v prores_ks -profile:v 4444 -y ks.mov
  The glitch expresses itself deterministically as blinking black
  
  rectangles on random frames (for example on frame 21, 54, 71, 79, ...).
  Even with the proresdec from FFmpeg, overreads actually happens while
  
  reading the run-minus-1 value (around val = get_bits(gb, 4) in
  
  unpack_alpha()). This doesn't seem to cause any particular issue because
  
  it simply overreads into the next slice, and because the decoder is
  
  resilient, but it's still a problem.
  The investigation leading to this fix was made possible because of paid
  
  work for Jitter (https://jitter.video).
  Fixes ticket #10255.
