• Running ffmpeg with Mac's Automator to remove metadata

  11 février 2019, par sd100

  Hi so I am having problems running ffmpeg on a folder of movie files with Mac’s automator. My goal is to select a folder and right click/select service and automatically the script should run on only movie files (of mp4 type).

  So I have a Automator workflow receives files or folders in finder. Then I have "Selected Finder items" and then run shell script (code below).

  This works but firstly it gives the ffmpeg verbose output in the results window in the mac which I have to press ok. I tried the "-hide_banner -loglevel panic" but the script doesn’t work then.

  Secondly the "Selected finder items" works but I want to only select a folder and automatically the automator script should go in the folder and run the shell script on only mp4 files (movie).

  Is there anyway to set both requirements ? Any advise would be appreciated !

  Code I’ve tried :

  for f in "$@"
  do
  /usr/local/bin/ffmpeg -i "$f" -map_metadata -1 -c:v copy -c:a copy "$f%.mp4"-new.mp4 ;
  done

  Also am trying to move all converted mp4 files to a directory in the current directory with shell code like this :

  for f in *.mp4 ; do ffmpeg -i "$f" -map_metadata -1 -c:v copy -c:a copy "converted/$f" ; done

  This doesn’t work either in automator as I don’t know how to move the ffmpeg output files into another directory via automator.

  Je viens de tester sur SPIP 3.1.6 branché sur une base MySQL (MariaDB) et la recherche renvoie bien l’article intitulé "Secrétariat général" dans les trois cas. Tu cites le bug #3162 mais celui-ci est résolu, je ne comprends pas trop.

• Transcoding and Streaming a video file for Android

  2 août 2013, par Yaron Budowski

  I'm trying to encode a local/static input file (can MP4, for example) into a smaller video file (either by resizing, lesser quality video, etc.) and stream it in parallel (i.e. I can't wait for the encoding process to finish before streaming it back), so it can be played by an Android client (the standard Android video player).

  So I've tried using ffmpeg as follows :

  ffmpeg -re -i input.mp4 -g 52 -acodec libvo_aacenc -ab 64k -vcodec libx264 -vb 448k -f mp4 -movflags frag_keyframe+empty_moov -

  Notice I'm using stdout as the output so I can run ffmpeg and stream its output on the fly

  However, such methods (and other similar methods) don't seem to work on Android - it can't simply play it once it receives "non-standard" files (such as a fragmented MP4s) - it seems like the empty moov atom messes it up.

  I also tried other container formats, such as 3GPP and WebM.

  I'd love to hear any kind of input on this issue...

  Thanks
