  • ffmpeg output separate channel from an input with multiple channels

    11 octobre 2017, par tiras muturi

    i run this command to be able to stream a udp live stream to a http live stream that is playable using a mobile application that am building.
    its just a stream with audio streams only.

    ffmpeg -i udp ://@localhost:1111 -map 0:a http://localhost:8090/feed1.ffm

    Input #0, mpegts, from 'udp://@localhost:1111':

    i really want a way i can be able to map every input stream to have an output stream that can be accessed separately from the other like maybe if i need the first stream maybe i will just

    ffplay http://localhost:8090/feed1.ffm

    and if i need the 7th stream i will just

    ffplay http://localhost:8090/feed7.ffm

    Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.

    this is my header information

  • Anomalie #4124 : changer de fournisseur de vignette ou les supprimer

    6 avril 2018, par cam.lafit -

    Salut

    Par défaut je ne pense que la fonctionnalité des aperçus doit être
    gérée dans SPIP même. Comme noté on a entre autres raisons la
    dépendance à service tiers non maîtrisés.
    Je ne pense pas non plus qu’on doive fournir un service spip sur ce
    sujet, comme on peut le voir avec la danse des services existants
    c’est une plaie à maintenir.

    Le fait de gérer ceci via un plugin simplifie la mise à jours des
    serveurs de vignette. Thumbsite a été codé pour permettre l’ajout et
    le retrait simple d’un générateur d’aperçu. Donc si easy-thumb est
    manquant c’est facile à faire.

    Pour ma part par défaut, on devrait avoir l’option 2 : retirer la
    gestion des vigenttes. On laisserait 2 plugins faire mieux si besoin
    (un pour les aperçus sans présupposer de leur usages et un pour
    surcharger statistiques si besoin)

  • Automatically match output file with input file (Applescript x FFMPEG)

    2 mars 2018, par Wallie

    I use the following AppleScript as an Automator Service to right click a video file in the finder and burn in a matching subtitle file (.ass) with an ffmpeg terminal command. In this case ffmpeg encodes a new Prores 422(HQ) file.

    on run {input, parameters}
    
tell application "Terminal"
    
    activate
    
    set filesString to ""
    
    repeat with file_ in input
    
        set filesString to filesString & " " & quoted form of (POSIX path of file_)
    
    end repeat
    
    do script "for f in" & filesString & "; do  
    
base=$f  
    
ffmpeg -y -i \"$base\" -c:v prores -profile:v 3 -pix_fmt yuv422p10le -vf \"ass=${base%.*}.ass\" -c:a copy \"${base%.*}_sub.mov\";
    
done"
    
    end tell
    
    return input
    
end run

    Would it be possible to automatically match the output file and it’s codec to the input file ?
    We use a lot of different input formats due to a mixed windows / mac environment (Prores (mov), dnxhr (mxf/mov)) and I would like to not have 8-12 encoding options in the finder service menu’s of the workstations :).

    Thanks in advance !!
