• Youtube automatic creating and starting live stream with ffmpeg Python

  20 août 2023, par MrKolia1_1

  I'm trying to create a new broadcast on the channel and then start the stream so that the video is broadcast, the problem is that I can't start the broadcast after it is created, it is in the scheduled, how can I start the broadcast ?

• input/output error with ffmpeg using an input URL in docker

  12 décembre 2023, par Grimou

  I need to use ffmpeg to listen to an rtmp url within a running docker container using ffmpeg.
my ffmpeg command is quite simple : ffmpeg -listen 1 -i rtmp://localhost:1935/live/app ./output.wav

  


  ffmpeg seems to start correctly and listen to the url.

  


  But, when I start the stream (using OBS Studio) I have an input/output error. Here is the logs (with debug log level)

  


  ❯ ffmpeg -loglevel debug -listen 1 -i rtmp://127.0.0.1:1935/live/app ./output.wav

  The last 3 lines only appear when I start the stream.

  


  It doesn't seems to be a permission problem with the file system, since using ffmpeg -i ./test.mp4 ./output.wav works inside the container.

  


  I also did not find any problem with the network. I am currently using network_mode: "host" in my docker_compose.yml and the logs show that it did receive data before the error appear.

  


  It also doesn't seem to be a problem with the ffmpeg command, since the exact same command works when using it without docker involved.

  


  What else could be the problem ?

  


  here is my docker_compose.yml

  


  version: '3'

services:
  ffmpeg-container:
    build:
      context: .
    network_mode: "host"
    tty: true  # Allocate a pseudo-TTY for interactive use

  I'm having trouble using FFmpeg to host an RTSP server for continuous video streaming. The command I'm using is :

  Can anyone help me identify and fix the problem with this command ? I want to loop the video infinitely on the RTSP server. I've tried variations with different formats (e.g., mp4 and ts), but the issue persists.

  


  Any insights into resolving this error would be greatly appreciated.
