• ffmpeg, v4l, snd_aloop ... sound asyncron (alsa buffer xrun)

  28 janvier 2019, par Tobias

  I’m trying to create a stream that automatically reloads random inputs. I would like to extend this to a database later.

  Each time ffmpeg finishes and starts again, so the input changes, the connection to the rtmp is interrupted briefly causing the whole connection breaks down. I then tried to separate audio and video, to send them to virtual devices and read from there again. Split the stream on virtual devices, reassemble them directly and send them to rtmp. If the input is then exchanged, the sending to the devices interrupts what does not bother the second ffmpeg. As soon as I stop sending to the devices the fps go very slowly (10 - 20 sec) from 25 to 0. Only then does the transmitter ffmpeg break the connection to the rtmp. The script which exchanges the inputs needs only one second. A practical test showed that everything works as desired.

  I can quite comfortably change the input while the second ffmpeg maintains the stream ...

  The joy did not last long. The sound is good 1 sec delayed. But sporadically. Sometimes everything works great. Sometimes the sound is offset.

  I wrote several scripts for this.

  Background :

  1. File is selected by random
  2. Media file is split and written to / dev / video0 (v4l loopback) and alsa default (snd_aloop loopback)
  3. Put the splits together again and stream them to a rtmp server

  Code that selects the input and sends to / dev / video0 and alsa default

  #!/bin/bash
  
  
  
  cat /dev/null > log
  
  
  
  while true;
  
  do
  
  
  
    WATERMARK="watermark.png";
  
    dir='/homeXXXXXXXXXX/mix'
  
    file=`/bin/ls -1 "$dir" | sort --random-sort | head -1`
  
    DATEI=`readlink --canonicalize "$dir/$file"` # Converts to full path
  
  
  
  if [ -z $DATEI ]
  
  then
  
    echo "Keine Datei gefunden" >> log;
  
  else
  
    START=$(date +%s);
  
    echo "Sende $DATEI" >> log;
  
    ffmpeg -re -y -i "$DATEI" -c:v libx264 -vf "fps=25,scale=640:480,setdar=4:3" -async 1 -pix_fmt yuv420p -preset ultrafast -map 0:0 -f v4l2 -vcodec rawvideo /dev/video0 -f alsa default
  
  fi
  
  
  
  DOKILL=`cat kill`;
  
  if [ "$DOKILL" = "1"]
  
  then
  
    break;
  
  fi
  
  
  
  done

  The sound is then absolutely unsynchronized ...

  Does anyone have any advice and can help me ?

    -f v4l2 /dev/video90

  Which results in the following error :

  What I tried and didn’t work :

  • use -f h264 for the output, which ends in a av_interleaved_write_frame(): Invalid argument error

• 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 :
