• 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 ?

  On the first 3 filters, I try to fill/crop the videos, to match 512x288
  On the next filters crop/fill the image to 640x874
  on the next 2 filtes, I add some padding to the top and middle video, of 5 pixels.

  The total height of the left column should be 288*3 + 5*2 = 874

  But when I run this command I get this error :

  Input 1 height 874 does not match input 0 height 872.

  Where did those 2 pixels go ? If instead of videos on the left, I use images, it works alright. Only with some videos, it seems to destroy those extra 2 pixels somehow.

  What is going on ? How could I fix it ?

  I’ve been using the sickbeard_mp4_converter for a while to convert video files to mp4 by generating a script for ffmpeg. I’m not sure what I changed, but the ffmpeg script it generates no longer works and I’m having trouble debugging it. Can anyone tell from my log what the issue is ? Yes, its supposed to be an mp4 to an mp4, which is typically fine.

  I’m at the point where I’m using an mp4 that worked with the same autogenerated script yesterday but it no longer is. I remember updating ffmpeg but downgrading did not resolve the issue, though I may have not downgraded enough.

  ffmpeg 4.1.4
