• FFMPEG Error while processing the decoded data for stream #0:1

  2 décembre 2020, par Michael Joseph Aubry

  When using the FFMPEG command in my Lambda function I am getting this issue (version 4.2.1). When using it on my local machine it works fine (4.3.1).

  The same error occurs when I have a .jpg output on disk i.e /tmp/test.jpg

  


  This is the exact log from cloudwatch

• How to convert wav audio file to aac in python ?

  2 juin 2021, par yaya49

  I have a project about audio compression, I've been working with pydub I am using the function export() to write and save the file it works perfectly fine from aac to wav but doesn't the other way around it gives me this error : (From what I understood, ffmpeg doesn't support the aac format for this function )

  


  Encoding failed. ffmpeg/avlib returned error code : 1

• ffmpeg xfade audio out of sync

  1er décembre 2020, par Richard

  hi I am using ffmpeg xfade to concat two clips, the transition looks fine, but the second clip has no audio in the output. I don't find more information about this in https://trac.ffmpeg.org/wiki/Xfade and the official doc. Can I keep the audio of both clips in sync ?

  


  I'm puttting the complete log below, it's massive
