• How to resolve "runOnReady command exited with code 0" when restreaming a stream using Mediamtx ?

  2 juillet 2023, par Emad Helmi

  I'm attempting to publish a stream to the RTMP port 1935 using a ffmpeg command with Mediamtx (v0.22.2). Afterward, I want to restream the mainstream to another path using the runOnReady command in the config file. However, I'm encountering an issue where the runOnReady command exits with code 0.

  


  Steps to Replicate :

  


  

  1. Use the provided docker-compose.yml file :

  


  


  version: "3.8"

name: mediamtx
services:
  mediamtx:
    image: aler9/rtsp-simple-server:v0.22.2
    container_name: media_mtx_rtsp_server
    ports:
      - "8554:8554"
      - "1935:1935"
      - "8888:8888"
      - "8889:8889"
      - "9997:9997"
      - "8000:8000"
    volumes:
      - ./configs/mediamtx/config.yml:/mediamtx.yml
      - ../volumes/hls/segments:/hls/segments


  


  

  2. Add the following path to the config.yml file :

  


  


  paths:
  show/test:
    runOnReady: ffmpeg -i rtmp://localhost:1935/show/test -c copy -f flv "rtmp://localhost:1935/compressed/test"
    runOnReadyRestart: yes


  


  

  3. Start the server using docker-compose.

  


  4. Publish an RTMP stream to the server using the following command :

  


  


  ffmpeg -re -stream_loop -1 -i files/sample-30s.mp4 -c copy -f flv "rtmp://localhost:1935/show/test"


  


  

  5. When I check the logs :

  


  


  2023/07/01 15:16:30 INF [RTMP] [conn 172.26.0.1:51044] opened
2023/07/01 15:16:30 INF [path show/test] runOnReady command started
2023/07/01 15:16:30 INF [RTMP] [conn 172.26.0.1:51044] is publishing to path 'show/test', 2 tracks (H264, MPEG4-audio-gen)
2023/07/01 15:16:30 INF [path show/test] runOnReady command exited with code 0


  


  So I can't watch the stream on the new path (/compressed/test)

  


• Python yt-dlp and ffmpeg error "merging of multiple formats but ffmpeg is not installed"

  27 mai, par T Tea Tie

  I am using the latest version of yt-dlp with Python 3.9.

  


  I am trying to download a youtube video in mp4 format with outputname as the youtubeid.mp4 and with best resolution not more than 4K.

  


  This is my Python code :

  


  ytid = '4cDqaLxrt6Q'
url = 'https://www.youtube.com/watch?v='+ytid
output_filename = ytid+".mp4"
    
with YoutubeDL({'format': 'bestvideo[height<=?4K]+bestaudio/best', 'output': output_filename}) as ydl:
    ydl.download(url)`#TODO debug FFmpeg and check if outputname is ok


  


  I expected to have an .mp4 file in my current working directory.

  


  Then I installed the latest version of FFmpeg from ffmpeg-master-latest-win64-gpl.zip and put ffmpeg.exe, ffplay.exe and ffprobe.exe in Scripts python folder (where yt-dlp.exe is). I also installed ffmpeg using pip install.

  


  The Traceback is :

• FFMPEG bash > folder processing > AI upscale - script ERROR ">" [closed]

  13 novembre 2022, par Jason Paul Michaels

  Trying to port a single file manual command from Topaz AI so I can run it as a part of a simple script allowing me to run multiple sessions from terminal. I am running MacOS with BASH 5.2 and when I run the script I get dumped to ">" instead of command prompt and no error message is displayed.

  


  This is my command -

  


  for f in *.mp4; do

    -hide_banner \

done


  


  I have a feeling it's something really simple I'm missing but I've gone through it a dozen times and can't seem to modify in any way to success.

  


  Thank you !

  


  Getting dumped back to ">" terminal prompt.
