• How to join 2 audio files into one using either ffmpeg or eac3to ?

  18 janvier 2017, par user3108268

  Not merge or mux into each other, because this is what I found so far, but take 2 .mp3 files e.g. 1 hour long each and join them and it becomes 1 .mp3 file with total of 2 hour long ?

  I did this :

  ffmpeg -i audio.mp3 -i 1.mp3  -filter_complex amerge -c:a libmp3lame -q:a 4 audiofinal.mp3

  But I think it encode both files into each other or something.

  And there’s nothing about this at https://en.wikibooks.org/wiki/Eac3to/How_to_Use

  I’d like to prefer command line solution and not Audacity or mp3DirectCut.

  edit : i tried eac3to m1.mp3+m2.mp3 1.mp3 but it doesn’t join them, output audio is the length of first file.

• FFMPEG : how to determine which filters are supported by specific hardware acceleration contexts ?

  7 juin 2020, par John Allard

  I'm having trouble figuring out precisely which filter graph operations are supported by each of the available hardware acceleration methods. I know, for example, that almost all of these methods perform simple operations like scaling, but what about more complicated ffmpeg filters like the new v360 filter or the mestimate filter ?

  



  There's this page (https://trac.ffmpeg.org/wiki/HWAccelIntro) that everyone finds when researching hardware accel with ffmpeg but it mostly touched on encoding and decoding and not filtering.
