  • ffmpeg - how to use pipe with amovie parameter ?

    19 février 2018, par user1347009

    I am looking for a solution to overlay to mp3 files in which the longer one will be played in the background and the smaller one will continue to play like a loop with that.
    My current code is working without pipe :

    ffmpeg -i 'longer.mp3'  -filter_complex "amovie='small.mp3:loop=999'[s];[0][s]amix=duration=shortest" new.mp3

    This code works like a charm but what i want to achieve is this :

    curl "any-url-to-api-to-audio-file" | ffmpeg -i 'longer.mp3'  -filter_complex "amovie='pipe\:0:loop=999'[s];[0][s]amix=duration=shortest" new.mp3

    This code is not working and its giving me error as well,

    All i want to do is to overlay two audio files via command line in which 1st audio file will be longer and the second one will be smaller.
    The smaller one will be repeated like a loop till the longer one play.

    Please tell me how can i do that ?

  • Evolution #3973 : Brancher inc/distant recuperer_url() sur une librairie récente

    20 février 2019, par Eric Camus

    Bonjour,
    Suite à un changement de machine pour nos SPIP (de WIMP vers LAMP (centos)) de nombreux flux RSS ne fonctionnaient plus, la cause : la fonction ’recuperer_url’ !!!.
    J’ai donc réécrit le corps de cette fonction avec la biblio PHP CURL a partir du code dans SPIP 3.2.0 (je sais que je suis en retard d’une version).
    Je vous le livre comme je viens de le finir après un léger debug.

  • ffmpeg : rewrite setting the stream disposition

    12 novembre 2021, par Anton Khirnov
    ffmpeg : rewrite setting the stream disposition

    Currently, the code doing this is spread over several places and may
    
behave in unexpected ways. E.g. automatic 'default' marking is only done
    
for streams fed by complex filtergraphs. It is also applied in the order
    
in which the output streams are initialized, which is effectively
    
random.
    

    Move processing the dispositions at the end of open_output_file(), when
    
we already have all the necessary information.
    

    Apply the automatic default marking only if no explicit -disposition
    
options were supplied by the user, and apply it to the first stream of
    
each type (excluding attached pics) when there is more than one stream
    
of that type and no default markings were copied from the input streams.
    

    Explicitly document the new behavior.
    

    Changes the results of some tests, where the output file gets a default
    
disposition, while it previously did not.
