• Compilied Ffmpeg not accepting -c:v and -c:a

  I complied FFMPEG with libsrt, with the online compile guide. https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu & how to compile ffmpeg with enabling libsrt

  It seems to compile correctly.

  But when running this command to convert a incoming srt stream to HLS, it doesn’t know the -c:a command. When switching the order, it runs that it doesn’t know about the -c:v command.

  I have searched the issue, but I could not find anything similar.
  Does someone what I have missed in the setup ?

  Everything is manual complied through the guide, this was the final command I run to compile FFMPEG :

  wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && \

• Improve bash script for checking when ffmpeg hangs streaming IP cam rtsp to youtube

  15 octobre 2022, par shakespeare

  Background

  



  I have a garden IP cam id like to stream live to youtube, so i decided to use ffmpeg to achieve this.

  



  The problem

  



  Whenever my IP cam restarts or loses connection ; ffmpeg will get stuck on the same frame and not resume once the IP cam is back online.

  



  My solution

  



  I have the ffmpeg output logged to a file, then have a script fetch the last line of the log every few seconds and compares frame numbers. If the frame numbers match, it kills ffmpeg process and starts another ffmpeg process.

  



  My question

  



  Is there a better way more efficient way ?

  



  logchecker.sh

  



  #/bin/bash
while true
do
    frameA=$(tail /home/daniel/output.txt -n 1 | sed -nr 's/.*frame=(.*)fps.*/\1/p')
    echo "$frameA"
    sleep 3
    frameB=$(tail /home/daniel/output.txt -n 1 | sed -nr 's/.*frame=(.*)fps.*/\1/p')
    echo "$frameB"

    if [ "$frameA" = "$frameB" ]
    then
        echo "Camera has hung"
        pkill ffmpeg
        echo "killed ffmpeg..."
        echo "Waiting 30 secs"
        sleep 30
        bash /home/daniel/ffmpeg.sh &
        echo "started ffpmeg.."
        echo "Waiting 30 secs"
        sleep 30
    else 
        echo "proceed"
    fi

    sleep 2
done


  



  ffmpeg.sh

  



  #!bin/bash
sleep 30
ffmpeg -f lavfi -i anullsrc -rtsp_transport udp -i rtsp://user:password@url:5544/live0.264 -bufsize 5000k -c:v copy -c:a mp3 -b:a 1 -f flv rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx 2> /home/daniel/output.txt
