  After referencing https://docs.yucca.app/en/troubleshooting/Segmentation_fault_core_dumped

  


  And using

  


  FFMPEG "Segmentation fault" with network stream source

  


  I thought I had this solved.
But still having the same issue as documented as fixed.

  


  Im using AmazonLinux 2023 distro in a Lambda custom image.

  


  Im trying to use baseImage from FROM --platform=linux/amd64 public.ecr.aws/lambda/nodejs:20

  


  Then doing- RUN dnf install nscd  -y in my Dockerfile allowing the nscd service to be installed per the answer.

  


  But, Im still getting the ffprobe was killed with signal SIGSEGV error with the new AmazonLinux Distro.

  


  Has anyone else faced this with the 2023 Distro ? Or have an answer to this question ?

  2 mars 2019, par sadegh

  I’m working on a video share service like youtube.com
  
  When an user upload a video i need to create a .m3u8 file
  below item are important :
  1- i don’t know what quality the file have (1080p,720p,480p,360p)
  2- i don’t know what format the file have (MPEG4(mp4),flv,AVI,WMV)
  3- i have .str subtitle
  
  I need export with this Specification :
  1- .m3u8 output support all quality(1080p,720p,480p,360p) if input file quality support
  2- .ts files length be the best practice (2sec, 5sec, 10sec or other is better)
  3- output file support subtitle
  
  What is the best command(or commands) for create this output using ffmpeg ?
  
  here is a very good .m3u8 that is my target :

• AWS Easiest way to generate video thumbnails without transcoding/MediaConvert

  6 février 2021, par dfranca

  I used to have a pipeline for transcoding video and generate the thumbnail running on MediaConvert.
Due to the high costs and because most of my videos are already on H264 I came to the conclusion that MediaConvert is not necessary
But I still want to have the thumbnail of course, to show on the videos list

  


  I have tried a few approaches :

  


  

  • Just removed the video output from the MediaConvert -> doesn't work, MediaConvert requires at least one video output, which is annoying, but ok

  


  • Changed my lambda to not create the pipeline and create the thumbnail using ffmpeg -> Works nice for small videos, but I can have videos up to 2GB, and for that I end up on lambda limitations of tmp storage and time (as I have to download the file from S3)

  


  


  Another approaches I thought about :

  


  

  • Using EFS attached to the lambda, but it seems that it is a bit expensive, and not sure if it works as I expect

  


  • Moving to a EC2 instance instead of lambda and a SQS to communicate with the instance, but this adds a lot of complexity and moving parts to something that I want to be simple and that has only one function : generate ONE thumbnail, it seems I'm overcomplicating

  


  • Using a client-side solution and capturing the thumbnail on the fly while loading the list of video, not sure if this will work and how performance would be affected.

  


  


  It would be perfect if AWS provides a similar service as MediaConvert, but that I could have thumbnails only output, but I couldn't find anything, not even close.

  


  Do you have any other idea on how could I approach this in the simplest way possible ?
