• FFMPEG No encoder found for codec id 8

  3 septembre 2018, par raspiboele

  I’m using a Raspberry Pi to restreem a (https) .m3u8 stream, to a local MJPEG-stream with FFMPEG.
  Becaus I have a Nest Cam / Nest Hello and I want to import that stream into my Fibaro Homecenter (Smarthome Basestation), but the Fibaro Homecenter only eats the MJPEG format. So I made a Raspberry Pi with FFMPEG to do the trick.

  This is my /etc/ffserver.conf file :

  HTTPPort 8090
  
  
  
  HTTPBindAddress 0.0.0.0
  
  
  
  MaxHTTPConnections 2000
  
  
  
  MaxClients 1000

  As you can see, I get an error : no encoder found for codec id 8
  It is frutstrating me, because I’m looking for a solution for three days now. I can’t even find a list of encoders and the coresponding ID’s. Do I have to enable maybe something in the ./configure ?

  My target is to get a stream at : http://localhost:8090/test1.mjpg

  Can anyone help me please ?

• ffmpeg : mix/merge multiple mp3 files, some do not mix

  28 août 2018, par C. Ovidiu

  I am trying to merge multiple mp3 files on top of each other on a CentOS 7 server.

  I am trying with ffmpeg but I have mixed results. When mixing 4 files, the last one for example does not mix with the others and is not audible in the final output.

  If I mix this file with another one or two(so max 3 files merged), it works.

  Is there a limit when merging ? For reference, each file is about 10mb is size and 5:00 minutes long.

  This is the command I am using

  ffmpeg -i /var/www/vhosts/site/httpdocs/uploads/tracks/1.mp3 -i /var/www/vhosts/site/httpdocs/uploads/tracks/2.mp3 -i /var/www/vhosts/site/httpdocs/uploads/tracks/3.mp3 -i /var/www/vhosts/site/httpdocs/uploads/tracks/4.mp3 -filter_complex amerge -ac 2 -c:a libmp3lame -q:a 4 /var/www/vhosts/site/httpdocs/uploads/mix.mp3

  The output after merging is this :

  Is there a way to solve this, or at least to know what the issue is ?

  Also, some people recommended sox, but I can’t figure how to install it on CentOS.

  Any other alternatives will also help.

  Thank you

• ffmpeg : video codec ansi not compatible with flv

  11 septembre 2018, par diatomym

  lets say i have 10 video files, encoded with the following command in ffmpeg

  ffmpeg -i input.mp4 -c:v libx264 -preset medium -maxrate 6000k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 file.flv

  now that all files match in codec, what i want to do is stream all those files via RTMP. for that, I’ll need to create a concat list. i also want the stream to infinitely repeat those 10 files. to do all these things, I use this command :

  ffmpeg -threads 2 -re -fflags +genpts -stream_loop -1 -i mylist.txt -c copy -f flv rtmp://link.to/RTMP

  when doing that, I get the following error output :

   ffmpeg -threads 2 -re -fflags +genpts -stream_loop -1 -i mylist.txt -c copy -f flv rtmp://link.to/RTMP
