• ffmpeg stream with static image and list audio

  17 août 2022, par dunghoitentao

  I used this command to livestream :

  


  ffmpeg -f concat -safe 0 -i list.txt -loop 1 -i bg.png -c:v libx264 -preset ultrafast -c:a copy -f flv rtmp://a.rtmp.youtube.com/live2/****


  


  with list.txt :

  


  file 1.mp3
file 2.mp3
file 3.mp3


  


  It's work, but not good, stream very bad and stop after some hours. Anyone have a better code ? Please help, thanks.

  


• automatically run script recording video at interval using command line and ffmpg

  29 décembre 2014, par arrie

  I’m really a beginner noob newbie command line noob. But. I’m trying to create a script that automatically starts my isight camera when turning on my mac laptop. It should create clips of about 5 seconds at an interval of 5 hours or so. (These numbers I can change of course later on if I have the basis for my script).

  So what I in fact need is (i think) a launch script, that launches a video recording script.

  Right now I’m as far as my video recording script, which is not finished : camera.sh

  #!/bin/bash
  
  
  
  FNAME=videocapture_`date +"%F_%H_%M"`.mpg
  
  echo $FNAME
  
  
  
  ffmpeg -f -t "0.20avfoundation -i "" $FNAME

  ---

  This in fact records a video when I play the script in the command line, until I tell it to quit. These videos are then named according to the date etc. But of course I want it to automatically record videos, in an already determined duration. And I just can’t seem to figure out how to make it happen. I come back to different kind of scripts using isight capture, which in fact doesn’t seem to exist anymore, and even so, I would like to stay with my own basis script just because I understand it haha.

  Hopefully someone here can help me figure this out ! Much appreciated :) Thanks !

• Zoneminder Watermarking on MP4 video from custom ZM branch

  6 janvier 2015, par moeiscool

  The ZM i have installed is the video branch. I followed these instructions to install it.
  https://github.com/ZoneMinder/ZoneMinder/tree/video
  https://github.com/ZoneMinder/ZoneMinder/issues/452

  I am looking to watermark my recordings. I have successfully achieved what i want on regular ZM. I just need it on the MP4 branch version of ZM. I have used ASR to search for "ffmpeg" and "mp4" but i only found anything relevant to video creation in zmvideo.pl... but i think zmvideo.pl is only for generating videos from JPEG files. I simply want to have the watermark appear on the mp4 file when it is created.

  So in short after a long explanation : Where should I be looking for the commands that create the MP4 files in ZM ? or do i have to add them to jpeg frames somewhere or something ? sorry for the noobiness... I have spent at least 3 hours looking for this and I’m actually sweating from frustration. ANY help at all would be appreciated :) Thanks in advance.
