• Batch convert MP3 and static image to AVI with FFMPEG

  8 décembre 2013, par user3027136

  I'm tired of searching for this problem. I have found 2 solutions here, but both work only partially.
  What I want to do is to convert all the MP3 inside a folder (if possible subfolders, too) to avi or anything else accepted by Youtube. I have created 2 .bat that should do this (according to the other threads here). They don't, one of them creates the avi without the image (black) and the other seems to capture the screen.
  Here they are.
  If you know about ffmpeg please point me to the right direction. Thank you.

  This one uses mp3info.exe - to be honest I have no idea what mp3info does, I just guess it finds the lenght of the song to be mathed later with the length of the video.

  @echo off
  
  for %%a in (*.mp3) do (
  
  for /f "delims=" %%b in ('mp3info.exe -p %%S "%%a"') do (
  
  ffmpeg -i "%%a" -loop 1 -r 1 -i "cover.jpg" -acodec copy "%%~na.mp4" -t %%b
  
  )
  
  )

  This seems more simple, runs faster but captures the screenshot and ignores the cover.jpg file.

  @echo off
  
  for %%A IN (*.mp3) DO ffmpeg -i "%%A" -i "cover.jpg" "%%A.mpg"
  
  done

  mp2info.exe, cover.jpeg and the .bat scripts are in the same folder with the .mp3 files.

• Why doesn't the lame mp3 codec (libmp3lame) create XingHeaders ?

  5 novembre 2012, par user784637

  I downloaded a video from youtube whose audio was encoded in aac and transcoded it to an mp3 using the libmp3lame codec.

  $ ffmpeg -i video.mp4 -vn -acodec libmp3lame -- test.mp3

  Now when I try to write id3 tags to it using the taglib example tagwriter I get the following warning :

  $ ./testwriter -t 'stuff' test.mp3
  
  TagLib: MPEG::XingHeader::parse() -- Xing header doesn't contain the total stream size.

  The id3 tags are written and display correctly, but the lack of the XingHeaders causes older players to loop the song several times.

  Why doesn't the lame mp3 codec create XingHeaders ? How do I create XingHeaders ?

• Ffmpeg not working for larger size file in PHP

  29 juillet 2019, par MrinmoyMk

  I want to upload different audio formats files and compress and convert them into mp3 file using ffmpeg in php. I have already installed ffmpeg and is working fine for files below 0.9 mb. Whenever I try to submit files larger than 0.9 mb then the action is not completed. It may be there is some mistake in my VPS server configuration or mistake in my PHP codes. Could you please help me. My code is

  if (isset($_POST['submit'])) {
  
  
  
  $path = "song/"; //set your folder path
  
  $mp3_local=$_FILES['mp3_local']['name'];
  
  
  
  $tmp = $_FILES['mp3_local']['tmp_name'];
  
  
  
  
  
  exec("ffmpeg -i ".$tmp." -ab 96k ./out96/$mp3_local.mp3");}

  My php configuration is
