• 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 transcode to live stream

  14 septembre 2016, par brayancastrop

  I need to display a ip camera stream in an html video tag, i have figured out how to transcode to a file from the rtsp stream like this

  ffmpeg -i "rtsp://user:password@ip" -s 640x480 /tmp/output.mp4

  now i need to be able to be able to live stream the rtsp input in a video tag like this

  <video src="http://domain:port/output.mp4" autoplay="autoplay"></video>

  I was trying to do something like this in my server (an ubuntu micro instance on amazon) in order to reproduce the video in the video tag but didn’t work

  ffmpeg -i "rtsp://user:password@ip" -s 640x480 http://localhost:8080/stream.mp4

  instead i got this log

  [tcp @ 0x747b40] Connection to tcp://localhost:8080 failed: Connection refused
http://localhost:8080/stream.mp4: Connection refused

  i don’t really understand what’s happening, not sure if it’s sending the output to that url or serving the output there and this, i’ve been checking the ffmpeg man docs but i didn’t find any example related to this use case and also other questiones like this one FFmpeg Stream Transcoding which is similar to my last try without success

  btw, this is the camera i’m using DS-2CD2020F-I(W) - http://www.hikvision.com/en/Products_accessries_157_i5847.html
  they offer an httppreview but it’s just an img tag source which updates but appears to be unstable

  This is my first time trying to do something like this so any insight about how to achieve it will be really usefull and appreciated

• How To Install FFMPEG on Elastic Beanstalk

  13 avril 2017, par Nick Lynch

  This is not a duplicate, I have found one thread, and it is outdated and does not work :
  Install ffmpeg on elastic beanstalk using ebextensions config.

  I have been trying to install this for some time, nothing seems to work.
  Please share the config.yml that will make this work.

  I am using 64bit Amazon Linux 2016.03 v2.1.6 running PHP 7.0 on Elastic Beanstalk
