• Failed to install ffmpeg. Failed to download resource "x265"

  19 août 2020, par Olha Olha

  I was trying to run "brew install ffmpeg" and two download links failed. So it failed the installation.

  


  Those are the links that aren't working :

  


  ==> Downloading https://mirrors.edge.kernel.org/pub/software/scm/git/git-htmldocs-2.28.0.tar.
==> Downloading https://bitbucket.org/multicoreware/x265/downloads/x265_3.4.tar.gz


  


  I got this errors :

  


  Error: Failed to download resource "git--html"

• AWS Lambda in Node JS with FFMPEG Lambda Layer

  29 mars 2023, par mwcwge23

  I'm trying to make a Lambda that takes a video and puts a watermark image on it.
I'm using Lambda with NodeJS and FFMPEG Lambda Layer I took from here :
https://serverlessrepo.aws.amazon.com/applications/us-east-1/145266761615/ffmpeg-lambda-layer

  


  I got these two errors and I don't have a clue what do I did wrong :
errors

  


  Please help me :)

  


  (by the way, if you have an easier solution to put a watermark image on video that'll also be great)

  


  That's my code (trying to put a watermark image on a video file) :

• working ffmpeg command fails when using in nginx with rtmp module

  7 juin 2017, par Rafael Linux User

  I have a tested code I did in a "bash" file. It works perfect on shell. I change only params to get it to work with nginx rtmp module, but ffmpeg says always and understandable error. This is the code :

  exec_push ffmpeg -re -y -i rtmp://localhost:1935/live/$name  \
  
                              -c:v libx264 -c:a aac  \
