• 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

  


• android live streaming - h264 decoding

  18 juin 2015, par alex_muc

  Since i’m a little familiar with android and video streaming, i know it’s complicated to handle live video streams from device to device.

  Requirement : play incoming raw h264 stream

  Are there any ways beside serving rtp/rtsp to playback the stream ?
  VideoView needs local rtsp or http server to handle the stream and i cannot believe, that there are no other ways to simply play it.

  Could be GStreamer / FFMpeg a good solution to decode the stream ?

• ffmpeg continuous live streaming of dynamic files from directory

  4 septembre 2022, par user72261

  So I have been using ffmpeg to create a live stream from files stored in a folder using concat list.

  


  This works perfectly for local, static content but I have a security system in my warehouse that uploads .mp4 files to my server in the office.

  


  This system doesn't have any live stream functionality so I would like to set up a live stream myself using ffmpeg to continually read the latest files from the folder.

  


  I tried setting up a script to read all files in the directory and sort them based on the file name that is a UNIX timestamp of the date/time the video was taken. Then had the script select the latest segments after that last used segment and create a new concat list such as below

  


  file '00000.mpd'
file '00001.mp4'
file '00002.mp4'
file '00003.mp4'
file '00004.mp4'


  


  After doing some reading I found out to make it loop that file you could reference its self in the list like so

  


  file '00000.mpd'
file '00001.mp4'
file '00002.mp4'
file '00003.mp4'
file '00004.mp4'
file 'concat.txt'


  


  This seemed to work ok until I started getting the error impossible to open concat.txt. This file doesn't exist, which I can only guess is because ffmpeg is trying to open the file as its being updated by the script.

  


  Has anyone come across this before or know another way to do it ?
