• ffmpeg trimming audio WAV files and setting timecode

  14 juillet 2022, par user19551045

  I am currently trying to cut an audio file to match the length of a video (without combining the two...just looking at timecodes) and produce a trimmed audio file that has a timecode that will match up with the video, the video is considered the absolute truth.

  


  Currently, the issue is that the timecodes from the original audio file do not get carried over into the new cropped audio file. So, the starting timecode is now 00:00:00:00 instead of say 07:20:02:14. Even using the -timecode commands and trying to hardcode the timecode that way doesn't seem to do the trick. I am wondering if there is any way around this ? I just want to do as minimal to the raw audio as possible...just change the audio file's length while setting the timecodes so the new audio will line up with the video. Any thoughts/suggestions welcome !

  


  Currently I have tried two options that don't seem to work :
using ffmpeg cmds :

  


  
        cmd2 = r'{} -ss "{}" -i "{}" -codec copy -timecode "{}" "{}"'.format(
            FFMPEG_PATH,
            abs(tc_diff_in_seconds),
            audio_path,
            "17074647",
            out_path
        )


  


  and also using pydub :

  


          current_audio = AudioSegment.from_wav("{}".format(audio_path))
        start_time_in_milli = abs(tc_diff_in_seconds*1000)
        end_time_in_milli = start_time_in_milli + video_dur_in_seconds * 1000
        trimmed_audio = current_audio[start_time_in_milli:end_time_in_milli]
        trimmed_audio.export('{}'.format(out_path), format='WAV', parameters=["-timecode", "17:07:46:47"])


  


  Any thoughts/suggestions welcome ! Thanks

  


• Anomalie #3210 (Nouveau) : flux rss sur les forums

  5 mai 2014, par jluc -

  SPIP 2.1.26

  Dans les fichiers du répertoire prive/rss il y a dans le HTML des paramètres type= qui ne correspondent à rien
  et devraient être remplacés par des statut=

  Il y a aussi des valeurs de paramètres #ENVpage qui ne correspondent à rien et devraient être remplacés par #ENVstatut

  Dans forums_public, qui devrait renseigner sur les forums publics, il y a le critère en dur : statut IN publie,prop,off,spam
  il faudrait plutôt statut=publie
  et plus loin il y a #URL_ECRIREcontrole_forum,statut=prop... il faudrait plutôt statut=publie

  J’ai aussi une interrogation pour prive/rss.html : on y trouve #INCLURE*fond=prive/rss/(#ENVop|match’^\w+$’
  ce qui fait que pour surcharger il faut créer un sous répertoire privé dans le répertoire squelette.
  Est ce bien là ce qu’il faut faire habituellement ? Ne devrait ce pas plutôt être #INCLURE*fond=rss/(#ENVop|match’^\w+$’ ?

• ffmpeg - Convert files but keep Same Date Modification as Original ?

  9 septembre 2021, par user5894146

  So I want to start with that ffmpeg and powershell isn't really my strength but I have been using the following powershell command to convert every .flac file in a certain directory to a 320K file.

  


  dir *.flac | foreach {ffmpeg -i $_.FullName -c:v copy  -b:a 320k  $_.FullName.Replace('flac', 'mp3')}


  


  This works exactly how I want to without any album art being transcoded but I want to incorporate a way so that the new .mp3 files that are created have the SAME DATE MODIFICATION value of the .flac files. Is something like this even possible ?

  


  audio_ex.flac = Date Modification: 1/1/2010
audio_ex.mp3 = Date Modification: 9/8/2021


  


  should be instead

  


  audio_ex.flac = Date Modification: 1/1/2010
audio_ex.mp3 = Date Modification: 1/1/2010


  


  I have a folder of 6K files and want each original date modified to match the newly created files so if I can do the above command and also have the date mod time match within one execution, that would be ideal.

  


  I thought of manually changing each files mod time using 3rd party tools but it will be too time consuming.
