• 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.

  


• Local file creation of ffmpeg hls http stream

  10 juillet 2018, par Emilian

  After researching all the options for ffmpeg hls streaming and setting it up for uploading to a http server i encountered a problem, ffmpeg also creates local files for the segment/playlist in the current working directory.

  What im trying to achieve is upload to a server and serve the segments and playlist from memory and not from disk. Tried setting a http url for segments like this :

  ffmpeg -re -i filter_test.ts -f hls -hls_segment_filename http://localhost:3000/segment/playlist_%03d.ts -method PUT http://localhost:3000/segment/playlist.m3u8

  but that also didnt work.

  Is there any way to stop ffmpeg from creating local files for the hls stream and only upload them to the server ?

  In the logs it says

  [hls @ 00000274041104e0] Opening 'http://localhost:3000/segment/playlist_000.ts' for writing
  
  [http @ 00000274046a2fa0] request: POST /segment/playlist_000.ts HTTP/1.1

  but nothing about writing it to a file.
