• How to "extend" aws docker base image (.net core from scratch) by ... libs/ubuntu/ffmpeg ?

  26 avril 2022, par Nigrimmist

  i would like to use AWS Lambda through the image containers using .net core 3.1 and it is works fine for me in simplest code case. But i stucked with next scenario :

  


  By default, aws provide base image with .net core with aws libs based on "from scratch". So as i know, it minimal Linux that does not contains even package manager.

  


  I need to work with ffmpeg in the code, but to do it i need to install few packages and ... fmpeg. I have working code on image

  


  FROM mcr.microsoft.com/dotnet/runtime:3.1-bionic


  


  It is ubuntu with .net core runtime. But what is the right strategic in case of AWS Lambda image ? How can i ... merge them ?.

  


  Have few ideas, but not sure :

  


  

  1. use as is FROM public.ecr.aws/lambda/dotnet:core3.1 and try to install package manager, all depenendencies to use ffmpeg and so on ?

  


  2. Use mcr.microsoft.com/dotnet/runtime:3.1-bionic, somehow add required by amazon dependencies (how ? download content and attach from local ?) and configure it to run in Lambda runtime ?

  


  3. ... ?

  


  


  Will be glad to hear where is the solution here. Thanks !

  


• Facebook LIVE with ffmpeg error - av_interleaved_write_frame() : Connection reset by peer

  22 décembre 2016, par above14

  I’m trying to stream to Facebook a Live Video from an Amazon EC2 instance (c4.xlarge). I installed ffmpeg and stream with a command like the following

  ffmpeg -re -f concat -i /home/ec2-user/playlist.txt -f lavfi -re -i anullsrc=channel_layout=stereo:sample_rate=44100 -s 854x480 -c:a aac -strict -2 -ar 44100 -vcodec libx264 -f flv "{rtmp_link}"

  Everything works fine. I had LIVE videos that worked for up to 2 days in a row. Sometimes, without a reason, I got one of these videos interrupted with this error message :

   av_interleaved_write_frame(): Connection reset by peer

  I haven’t been able to figure out a reason for this error yet. The funny thing is that maybe I have 3 streaming going on in the same machine at the same time, and just one of them get stopped by this message. Other times this error happens where there’s just one streaming on the EC2 instance.

  Any ideas about how to find a solution ?

  EDIT

  We have installed a newer version of FFMPEG and the error now is more detailed. We have this message

   RTMP send error 104

  I haven’t found a lot about this issue online. Does someone know what error 104 means ?

• ffmpeg not working with filenames that have whitespace

  18 mai 2021, par cmw

  I'm using FFMPEG to measure the duration of videos stored in an Amazon S3 Bucket.

  


  I've read the FFMPEG docs, and they explicitly state that all whitespace and special characters need to be escaped, in order for FFMPEG to handle them properly :

  


  See docs 2.1 and 2.1.1 : https://ffmpeg.org/ffmpeg-utils.html

  


  However, when dealing with files whose filenames contain whitespace, ffmpeg fails to render a result.

  


  I've tried the following, with no success

  


  ffmpeg -i "http://s3.mybucketname.com/videos/my\ video\ file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
ffmpeg -i "http://s3.mybucketname.com/videos/my video file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
ffmpeg -i "http://s3.mybucketname.com/videos/my'\' video'\' file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
ffmpeg -i "http://s3.mybucketname.com/videos/my\ video\ file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d


  


  However, if I strip out the whitespace in the filename – all is well, and the duration of the video is returned.
