• Upload a LIVE HLS output from FFMPEG to Amazon S3 bucket

  22 janvier 2023, par Pit Digger

  I have an ffmpeg command that outputs live hls stream from a vod file to local disk. I would like to upload the HLS chunks and manifest file in real time to Amazon S3 Bucket. Is it possible to upload it directly from memory ?

  


  Here is the ffmpeg command

  


  ffmpeg -stream_loop -1 -re -i bunny_1080p_30fps.mp4 -c:v libx264 \
-x264opts keyint=30:min-keyint=30:scenecut=-1 -tune zerolatency -s 1280x720 \
-b:v 1400k -bufsize 1400k -hls_start_number_source epoch -f hls stream.m3u8


  


  Note that I have checked all questions here but none of them do that for a live stream and for multiple files output like hls or dash stream.

  


  One option that I have tried is using node-watch module and upload file on change notification, but that does introduce some buffering. But if there was any better option. https://github.com/yuanchuan/node-watch

  


• How to combine/concatenate videos stored in AWS S3 bucket based on title of the file name

  9 juin 2020, par orangecube

  I am using a service that allows me to record videos that get automatically pushed to a folder (submissions) in an S3 bucket. There are multiple videos however they need to be grouped together and concatenated so the output is one video per group.

  



  So, basically, any tips on how I can take videos based on the title and stitch them together ?

  



  Example :

  



  Submissions folder will have :

  



  a-100-2.mp4
a-200-6.mp4
b-123-5.mp4


  



  Expected output in processed folder :

  



  a.mp4     - (both 'a' videos get stitched together)
b.mp4     - (only 'b' gets sent over since there is only one video.)


  



  Thanks in advance !

  



  Edit : Some additional and detailed information below if it helps.

  



  The files will be labeled with :
name-location-video_token-stream_token.mp4

  



  Need help creating a script or process that will concatenate the videos using the procedure outlined below :

  



  Processing rules (back end) :

  



  


  1. Check if videos have same video_token in ‘submissions folder’. If so, keep the newest one and delete old ones.

  


  2. Take all videos in ‘submissions folder’ with same name and location in title and concatenate the videos. Save output video to a new folder in the bucket labeled as the location for the folder name. 
Output file name : 
name-location-year.mp4.

  


  



  EXAMPLE :

  



  Submissions folder :
joey-toronto-001-354.mp4

  



  joey-toronto-001-241.mp4 - this will be deleted

  



  joey-toronto-103-452.mp4

  



  alex-montreal-352-232.mp4

  



  alex-montreal-452-223.mp4

  



  Resulting output :

  



  Toronto folder :

  



  Joey-toronto-2020.mp4

  



  Montreal folder :

  



  Alex-montreal-2020.mp4
