• avfoundation error. Cannot detect list_devices

  12 septembre 2016, par xiaose

  I need to get ID for current screen and, as it said here, I tried to get list of all available input devices...

  Whith command ffmpeg -f avfoundation -list_devices true -i ''

  It works fine on two my Mac but on the third, with OSX 10.7.5 it does not works :

  $ ./ffmpeg -f avfoundation -list_devices true -i ''
  
  ffmpeg version 3.1.1 Copyright (c) 2000-2016 the FFmpeg developers
  
  ...
  
  Unrecognized option 'list_devices'.

  I got

  Unrecognized option ’list_devices’

  there and don’t know how to fix it. Could you help me with that ?

  Like I understand this situation, there is issue with avfoundation. It just doesn’t works correctly...

  From another side it gives me error :

  Unknown format ’avfoundation’

  $ ./ffmpeg -h demuxer=avfoundation
  
  ffmpeg version 3.1.1 Copyright (c) 2000-2016 the FFmpeg developers
  
  ...
  
  Unknown format 'avfoundation'.

  UPD : issue was in ffmpeg. That version what I used just does not support interaction with avfoundation

• FFMPEG - Convert MKV to MP4 with all streams (subtitles) and watermark

  24 juillet 2016, par ShinJii

  I spent few hours researching and still have problem...
  I want to convert .mkv file to .mp4 with watermark and subtitles (from mkv).

  I tried few commands but always error or success with watermark without subtitles.
  Here are some commands I tried (not all) :

  Partial Success - some files are converted with subtitles, but I have 153 files that are converted without subtitles... (both from .mkv to .mp4) :

  ffmpeg -i 025.mkv -vf "movie=logovideo2.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10,subtitles=025.mkv [out]" 25.mp4
  
  
  
  ffmpeg -i 001.mkv -i logovideo2.png -filter_complex "[0:v][1:v]overlay=0:0,subtitles=001.mkv[out]" -map "[out]" -map 0:a -c:s ass 001.mp4

  Fail - command with error :

  ffmpeg -i 001.mkv -i logovideo2.png -filter_complex "[0:v][1:v]overlay=0:0[out]" -map "[out]" -map 0:a -map 0:s -c:s ass 001.mp4
