• When assigning an IP via Docker container macvlan and sending video to that container, will the data be limited ?

  11 septembre 2023, par leejh

  I created a macvlan network as shown below.

  


  docker network create -d macvlan \
    --subnet=192.168.1.0/24 \
    --gateway=192.168.1.1 \
    -o parent=eno1 \
    macvlan_network


  


  And the container was created as shown below.

  


  The plan was to create a mistserver inside the container to send and receive video via IP.

  


  docker run -d --name mistserver1 --restart=always -v mistserver_config:/config -v /home/ketivrar/detr2:/home/shared_folder --net=macvlan_network --ip 192.168.1.16 r0gger/mistserver


  


  There is no problem when transmitting video in the directory using the Mist server.

  


  An error occurs when transmitting video using ffmpeg as shown below.

  


  ffmpeg -re -i test7_10.mp4 -c:v libx264 -preset medium -b:v 8000k -f flv rtmp://192.168.1.16/live/cam1


  


  If you run the above command, the following error will occur and it will stop.

  I wonder what the reason is...

  


  I created two streams on the Mist server and sent video to each stream simultaneously.

  


  ffmpeg -re -i test7_10.mp4 -c:v libx264 -preset medium -b:v 8000k -f flv rtmp://192.168.1.16/live/cam1

  It seems to stop before the total size of the two reaches 60000.

  


  This time, I sent the video using OBS.

  


  I confirmed that the connection was disconnected and reconnected at a similar time as ffmpeg.

  


  I think there is a size limit somewhere. Could you please tell me a solution or the exact problem ?

  fail...

  


  I only adjusted -b:v 5000k, but the results were mixed.

  


  Are there any resource limits for each container ?

  


  I didn't set it up separately.

  


• How to change the stream info and codec info of mp4 via Ffmpeg mux/remux code ?

  2 avril 2017, par Gohan1987

  Is it really possible to change stream information and video codec information using FFMPEG muxing / remixing code ?

  Consider this example :
  Major brand : isom
  Minor version : 0
  Compatible brand : isommp41
  Resolution : 1280 x 780

  Convert into another mp4 file
  Major brand : mp42
  Minor version : 512
  Compatible brand : isomavc1mp41
  Resolution : 359 x 288

  Note : without command line. Like using decode, sws_scale code wise ?.

   The results are consistent with tests/ref/fate/filter-metadata-scenedetect
   For the master, it'll detect more than 20 scene change for the same source.
