  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

    13 avril 2011, par

  • 2 source videos in FFMPEG... how to map audio ?

    21 juin 2012, par dcoffey3296

    i am currently placing 2 videos side by side in FFMPEG. Here is the command :

    ffmpeg -i input.mov -vf "[in] scale=1280:720, pad=2*1280:720 [left]; movie=right.mov, scale=1280:720 [right]; [left][right]  overlay=1280:0 [out]" -b:v 1000k -vcodec libx264 -an sidebyside.mp4

    I now need to manage the audio. I keep trying to specify :

    -acodec libfaac -ac 2 -map 0:1 -map 0:2

    to take the 2 audio channels from the first input and use them. I keep getting the error :

    [aformat @ 0x7febf2e01fc0] auto-inserting filter 'auto-inserted resampler 0' between the filter 'src' and the filter 'aformat'
    
    [aresample @ 0x7febf2e02180] [SWR @ 0x7febf40dd000] Input channel layout isnt supported
    
Error opening filters!

    I'm looking for the best way to specify which video provides the audio ! Thanks for any advice !

    Here's the complete output :
