• Non stop stream to rtmp with FFMPEG

  13 février 2020, par Надежда Перемен

  I want to stream to RTMP with FFMPEG. I need to dynamically change next play file, for that i use web urls for my localhost.

  I have PHP file located : http://127.0.0.1/mp3.php

  $file = '1.mp3';
  
  
  
  $mime_type = "audio/mpeg, audio/x-mpeg, audio/x-mpeg-3, audio/mpeg3";
  
  
  
  if(file_exists($file)){
  
      header('Content-type: {$mime_type}');
  
      header('Content-length: ' . filesize($file));
  
      header('Content-Disposition: filename="' . $file);
  
      header('X-Pad: avoid browser bug');
  
      header('Cache-Control: no-cache');
  
      readfile($file);
  
  }else{
  
      header("HTTP/1.0 404 Not Found");
  
  }

  And i run ffmpeg with this command line :

  ffmpeg -re -stream_loop -1 -i logo.png -stream_loop -1 -i http://127.0.0.1/mp3.php -ab 320k -c:v libx264 -f flv "rtmp://ms......."

  This works, but it playing only once time and FFMPEG returns an error :

  Seek to start failed
http://127.0.0.1/mp3.php: Function not implemented

  How can i fix it ?

• Removing file in windows batch script not working

  13 février 2020, par BluePrint

  I’m trying to create a batch script for trimming 25 seconds from the beginning of all mp4 files in a folder. The batch script is located in the same folder as the files, and there is a folder called trimmed in the same folder. This is my script so far :

  @echo off
  
  setlocal DisableDelayedExpansion
  
  
  
  :promptdel
  
  set /p delorig=Delete original file (default no)? [Y/N]: 
  
  
  
  if not defined delorig (
  
    set delorig=N
  
  )
  
  
  
  set "vartwo="&for /f "delims=YNyn" %%i in ("%delorig%") do set vartwo=%%i
  
  
  
  if defined vartwo (
  
    echo Please state Y or N!
  
    goto :promptdel
  
  )
  
  
  
  for %%a in ("*.mp4") do (
  
    echo Starting %%a
  
  
  
    rem "Need to rename since file names may contain whitespaces"
  
    ren "%%a" "working.mp4"
  
    ffmpeg -loglevel panic -hide_banner -i "working.mp4" -ss 00:00:25.000 -c:v copy -c:a copy "trimmed\%%a"
  
    ren "working.mp4" "%%a"
  
  
  
    echo %delorig%
  
    if %delorig% == "Y" (del "%%a" /f /q)
  
    if %delorig% == "y" (del "%%a" /f /q)
  
  
  
    echo %%a finished!
  
  )
  
  
  
  pause

  My problem is that the original file does not get removed regardless of if I input y/Y or n/N. What am I doing wrong ?

• Bash script for prepending a video intro file to a directory of videos using ffmpeg

  21 juillet 2016, par WesleyS

  I cooked up the following script to prepend an intro video to a directory of videos. I simply put the intro video one directory up, then run the script ./vidProcess.sh from the directory where all my videos that need the intro are located. I’m getting some varied results with this, but I believe I’m close to having a working script. I figured I’d share here in case anyone else finds this helpful and ask if you have any suggestions for making this work better. this requires ffmpeg.

  FILES=*.mp4
  
  INTRO=../MyIntro.mp4
  
  
  
  mkdir processed
  
  
  
  for f in $FILES
  
  do
  
    echo "Renaming $f file..."
  
    # Replace spaces with underscores and copy to "processed" directory
  
    cp "$f" "processed/${f// /_}"
  
  done
  
  
  
  for p in processed/$FILES
  
  do
  
    # Create text file with paths to both files
  
    echo "file $INTRO" >> temp.txt
  
    echo "file $p" >> temp.txt
  
    # ffmpeg command overwriting with processed file
  
    ffmpeg -y -f concat -i temp.txt -c copy $p
  
    rm temp.txt
  
  done
