• Run ffmpeg on Terminal MacOS [closed]

  6 mars 2013, par user2139175

  I'm rather new to MacOS and I cannot find it easy to working with Terminal to get ffmpeg run properly as I have on Window.

  I have got ffmpeg binary from http://ffmpegmac.net and I try running the executable in Terminal, it tells that the command not found ? The only way I can run it by now is using command : "open ffmpeg", but this way the Terminal open in another window and this is not what I'm expecting.

  Is there any ways to call ffmpeg directly in Terminal (just like run in on Windows cmd) or I'm missing anything ?

• ffmpeg convert MKV to MP4 while keeping Audio and Subtitle titles

  4 septembre 2017, par Fetts

  I am using ffmpeg to batch convert a bunch of MKV videos to MP4 videos. The code I use for this is :

  for %%a in ("*.*") do ffmpeg -i "%%a" -codec copy -map 0 "newfiles\%%~na.mp4"

  However, I cannot figure out how to keep the title for each audio track. For example, here is what I see when converting one of my videos :

  Stream #0:2(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp
  
      Metadata:
  
        title           : Director Commentary
  
  
  
   Stream #0:3(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp
  
      Metadata:
  
        title           : Production Commentary

  While these tracks appear in the converted MP4 file, the titles "Director Commentary" and "Production Commentary" are not kept. I’ve tried using different variations of map_metadata, but it doesn’t seem to work.

  Any thoughts would be appreciated.

• minimal ffmpeg build without filters

  1er août 2020, par Andrew

  I'm trying to build a minimal version of ffmpeg that is as small as possible, with only support to decode AAC audio in an MP4 container, and write it out to PCM or WAV.

  


  For some reason though, I can't find a way to build ffmpeg without it including all of these filters :

  


  Enabled filters:
aformat                 atrim                   hflip                   transpose               vflip
anull                   format                  null                    trim


  


  Is there any way to disable these ?

  


  I'm using this configure command :
