  9 décembre 2022, par user3813809

  I am trying to install ffmpeg to elastic beanstalk, I have created config file with below commands-

  



  packages:
  yum:
    ImageMagick: []
    ImageMagick-devel: []
commands:
  01-wget:
    command: "wget -O /tmp/ffmpeg.tar.xz https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-64bit-static.tar.xz"
  02-mkdir:
    command: "if [ ! -d /opt/ffmpeg ] ; then mkdir -p /opt/ffmpeg; fi"
  02-tar:
    command: "tar xvf /tmp/ffmpeg.tar.xz -C /opt/ffmpeg"
  04-ln:
    command: "if [[ ! -f /usr/bin/ffmpeg ]] ; then ln -sf /opt/ffmpeg/ffmpeg-3.4-64bit-static/ffmpeg /usr/bin/ffmpeg; fi"
  05-ln:
    command: "if [[ ! -f /usr/bin/ffprobe ]] ; then ln -sf /opt/ffmpeg/ffmpeg-3.4-64bit-static/ffprobe /usr/bin/ffprobe; fi"
  06-pecl:
    command: "if [ `pecl list | grep imagick` ] ; then pecl install -f imagick; fi"


  



  Till 05-ln everything seems to be fine, but on 06-pecl I am getting below error-

• ffplay attempt to subscribe to rtmp server failing with : RTMP_ReadPacket, failed to read RTMP packet header

  8 mars 2018, par johnnydonna

  I have an nginx rtmp server loaded with this docker image : https://github.com/DvdGiessen/nginx-rtmp-docker.

  In general I can stream to it fine with ffmpeg and most of the time connect to the stream fine as well with ffplay. However, for some people, they are unable to subscribe to the RTMP stream at all.

  ffmpeg hosts with this command :

  ffmpeg.exe -f,gdigrab,-framerate,20,-draw_mouse,1,-i,desktop,-c:v,h264_nvenc,-profile:v,main,-delay,0,-preset,default,-rc,vbr,-cq,36,-vf,scale=1024:-2,format=yuv420p,-r,20,-g,40,-y,-f,flv,rtmp://url

  ffplay subscribes with this command :

  ffplay.exe -fflags,nobuffer,-flags,low_delay,-an,-window_title,Screen of User,-framedrop,rtmp://url

  The URL does match the url to which the host is streaming from. What happens is that for about 30 seconds, nothing happens with the following ffplay output :

  nan    :  0.000 fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0<br />
nan    :  0.000 fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0<br />
nan    :  0.000 fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0

  which repeats until after a while I get the following error :

  RTMP_ReadPacket, failed to read RTMP packet header

  2018/mm/dd 12:--:--:-- [web] rtmp://url: Invalid data found when processing input

  I tried doing what this recommended in regards to the NGINX server setup here : https://github.com/arut/nginx-rtmp-module/issues/1039, setting my worker_processes to 1 which did not change anything.

  It seems like it may just be ffplay timing out but I cannot tell why it occurs only for a few users and not widely. If it is ffplay timing out, what can be done to fix the problem ? It doesn’t seem like an internet speed issue, as these subscribers have pretty good internet. I cannot replicate across different machines, only those few who have continued to have this problem. Any and all help would be appreciated !

• ffmpeg error on AWS lambda

  13 mars 2018, par anarchos78

  I’m trying to convert a jpg image to mp4 and transcode a mp4 file with ffmpeg on AWS lambda.

  For the first task I issue the following :

  ffmpeg -y -f lavfi -i anullsrc -loop 1 -framerate 30 -i test.jpg -t 2 -pix_fmt yuv420p -vf scale=640:480 -c:v libx264 -profile:v baseline -level 3.0 -c:a aac -map 0:a -map 1:v -strict -2 -preset ultrafast /tmp/jpg_output.mp4

  and for the second :

  ffmpeg -i /var/task/test.mp4 -c:v libx264 -c:a copy -strict -2 -v 9 -preset ultrafast -y /tmp/output.mp4

  The funny thing is that the aforementioned tasks (jpg conversion and video transcoding) complete successfully, both locally and on AWS lambda, but I’m getting the below error messages :

  Locally : "err : ffmpeg version 3.4.2 Copyright (c) 2000-2018 the FFmpeg developers"

  AWS LAMBDA : "err : ffmpeg version N-89977-gddd851f7cb-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2000-2018 the FFmpeg developers"

  Additionally, on AWS Lambda, the function exits with error, which results in re-execution of the function.

  I searched for solutions to no avail. Any suggestions ?
