• How to convert .mov files to .mp4 (H264) using ffmpeg using windows .bat file ?

  13 juillet 2013, par kheya

  I have a number of different video files (mov, avi, flv, mp4, 3gp, wmv) in a folder.

  I need to use a batch file that will convert all mov, avi, wmv, 3gp files in the folder
  Also I need to skip any flv, mp4 files

  I have this command, but it gives error and generates 0 size files :

  for %%F in (*.mov) do ffmpeg.exe -i "%%~fF" -vcodec copy -acodec copy "%%~dpF\%%~nF.mp4"

  The above line just tries to process mov files. I get same result for avi files.

  I want to keep the file name same. I get the file names correctly but it gives error :

• FFMPEG compiling on heroku

  17 juillet 2013, par Jan

  I have a Rails app running in heroku.

  I wanna watermark an original AUDIO-file with another AUDIO-file through a merging/mixing (amerge or amix) filter. Also fades and looping should work.

  FFMPEG must be compiled for this feature to run on heroku.
  My steps I got from this GIST which uses Vuclan

  https://gist.github.com/liufengyun/5055354

  Locally I use the following term to convert with Carrierwave which is an uploader :

  "-i Original.aiff -i public/watermark/#{ENV['WATERMARK_FILENAME']}.aiff -loop 1 -filter_complex '[1]afade=t=in:ss=0:d=1[4];[4]afade=t=out:st=#{self.evaluate_length-2}:d=2[5];[5][0]amix=duration=shortest[out]' -map [out]"

  This works with the ffmpeg built in on my mac.

  My compiled version for heroku does contain amerge, amix and the libavformat library.

  This is the log which I got from heroku when I go to my upload form and uplaod a file :
  (all this works, but only locally).
