• How to run bash script from NodeJS application correctly ?

  13 mars 2019, par z Eyeland

  I am running a node application that uses spawn child-process to start this script

  #!/bin/bash
  
  FILEPATH="$1"
  
  COMPRESSIONPATH="$2"
  
  ffmpeg -i $FILEPATH -vcodec h264 -acodec mp2 $COMPRESSIONPATH
  
  sudo rm $FILEPATH
  
  curl -H "Content-Type:application/json" -X GET 
  
  http://localhost:3000/clovis/api/led

  The script never finishes. If the ffmpeg compression command takes long then x amount of time then the process just stops and holds the process. I cant tell so by using the command ps-ef. Is there another way to start bash scripts from NodeJS other then spawn ? Does the NodeJS child-process have a time limit ?

• ffmpeg massive error spamming from FritzBox rtsp stream

  19 février 2019, par itzaiiro

  Im trying to offer a rtsp live TV stream via rtmp to my family, since the Fritz Box (which is offering the stream) has only 4 tuners -> at most 4 streams can be watched simultaneously.
  Im using ffmpeg to prepare the stream as dash stream and send it to my rtmp nginx. When i run ffmpeg im experiencing heavy image and audio artifacts in the final stream and error spams of doom in the console. I couldn’t find anything specific to my case on google. I read on the internet that AVM barely implemented the rtsp protocoll enough to get it to work with vlc mediaplayer.

  launch param :

  ffmpeg -i "rtsp://192.168.178.1:554/?avm=1&freq=114&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=1&pids=0,16,17,18,20,260,543,544,546,548,1621" -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 500k -minrate 500k -maxrate 500k -bufsize 1000k -g 60 -s 640x360 -f flv rtmp://192.168.178.15/dash/pro_sieben_low -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 1500k -minrate 1500k -maxrate 1500k -bufsize 3000k -g 60 -s 1280x720 -f flv rtmp://192.168.178.15/dash/pro_sieben_med -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 5000k -minrate 5000k -maxrate 5000k -bufsize 10000k -g 60 -s 1920x1080 -f flv rtmp://192.168.178.15/dash/pro_sieben_high

  ffmpeg output (windows) :
  stored in pastebin
  https://pastebin.com/p4HAyBi5

  Is there anyway to get this under control ? The original stream is running good with vlc, but its unwatchable after its out of ffmpeg.

  Edit :
  I was running/testing this on my windows machine, but my target for this task is a ubuntu 16.04 so here ffmpeg on target with pthread support :

  I have skipped few lines of output as there are many frames. So if you see at the end of output on both A and B sides and look at the number of I, P and B frames,the number of P and B frames on receiver B is more than that at sender A. Can anyone please tell me why there is a change in the number of frames ?
