• I need assistance of making a automated script for ffmpeg [closed]

  18 décembre 2024, par user2614404

  Currently i use this script that GPT generated :

  


  ffmpeg -c:v av1_qsv -b:v 0 -global_quality 20 -preset veryslow -look_ahead 64 -c:a copy -c:s copy G:\1ARC-movies\A-View-to-a-kill.mkv -i Y:\media\Movies\A_VIEW_TO_A_KILL_t05.mkv

  


  But sadly GPT being gpt, it hallucinates answers, and none of it's deeper automation code scripts were working when it made the scripts for a .ps1 script file.

  


  And as i find most of the docs quite overwhelming, i need help to simplify what i need. As i learn best when i get explained what i currently try to do, and not every variable ffmpeg can do.

  


  what i want the script to do is :

  


  1 : convert movies with AV1_QSV with "veryslow", as that's apparently from what i've read up being the best it can do

  


  2 : Global quality as close to 50 as possible (smaller, the better), as 20-6 gave the same range of percentage of 97% VMAF score, 22 gave 95%, so 20 is the largest number i can go, as VMAF via NMKODER reported any higher number was sub 97%.

  


  3 : Give it a main folder for movies and shows to scan, and convert all the media in there to their respective subfolders to a designated output folder.

  


  2 : Automatic crop detection, as some crops it to a 21:9 ratio, others has very small letterboxes. As GPT's code for that attempt for some reason used cpu instead of arc's quicksync.

  


  As this will be ran from powershell, and it's to replace my plex library, by transcoding all movies and shows, starting with the least watched ones/shows that my family has seen, as then those will be unavailable for them until unraid 7 is out of beta to read intel arc for av1.

  


• Why UA sniffing is generally bad, real-world example #1048577 : "That time a missing /s on navigator.userAgent (based on single-digit UA version assumptions) broke SM2 on iOS 8+ devices."

  Why UA sniffing is generally bad, real-world example #1048577 : "That time a missing /s on navigator.userAgent (based on single-digit UA version assumptions) broke SM2 on iOS 8+ devices."
  The upside : The fix is adding \s to a UA regex check targeting legacy iOS devices with broken HTML5 Audio support, so that the "OS 10 " portion of the UA string does not match the pattern "OS 1 ".
  This is a pre-emptive fix for the pending iOS 8 release, which reportedly includes the string "iPhone OS 10_10 like Mac OS X". Due to SM2 checking for /os ([12|3_0|3_1])/i which had broken HTML5 Audio() support, and not considering the far future possibility of "iOS 10" being included in the userAgent string at the time, HTML5 audio is incorrectly disabled on iOS 8 beta 3 and is likely to apply to the final iOS 8 release.
  This is a good example and reminder of why UA checks are generally bad, and dangerous ; similar issues hit other libraries doing UA and plugin checks both client and server-side when IE hit 10, and Flash hit version 10, so this iOS pattern change may affect some other libraries targeting iOS as well.
  

• Anomalie #3544 (Fermé) : mot "ré-initialiser"

  12 septembre 2015, par Franck Dalot

  Bonjour :-)
  SPIP 3.1.0-beta [22405]

  Il y a une faute
  https://core.spip.net/projects/spip/repository/entry/spip/ecrire/lang/ecrire_fr.php#L708
  Il faudrait écrire mettre le mot
  "réinitialiser"
  à la place de :
  ré-initialiser

  L’erreur semble présente aussi dans :
  https://core.spip.net/projects/spip/repository/entry/spip/ecrire/lang/ecrire_fr_fem.php#L710
  et
