• How can I convert a bitmap array to a jpg [on hold]

  31 mai 2014, par user3678446

  There is really not a lot of information about ffmpeg out there. And I thought maybe somebody can help me with this.
  I need the conversion so I can send them to a server and the the server to convert them back to bitmaps. And I am going to send a lot of them so I need this whole conversion process to be pretty fast.
  I would appreciate even a source of information or a starting point for my research.

• FFMPEG : merging multiple audio (MP3) and single image convert them into a video [on hold]

  9 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.
