  • Multilang : améliorer l’interface pour les blocs multilingues

    18 February 2011, by

    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.

  • How can I play libvorbis(ogg) streams using ffplay received with udp?

    31 March 2017, by crisman

    ffmpeg

    ffmpeg -f dshow -i audio="virtual-audio-capturer" -codec:a libvorbis -b:a 128k -ac 2 -ar 48000 -f mpegts udp://127.0.0.1:1111

    ffplay

    ffplay -codec:a libvorbis -b:a 128k -ar 48000 -ac 2 udp://127.0.0.1:1111

    not playing audio.

    Other codecs play back working, example below.

    aac working

    ffmpeg -f dshow -i audio="virtual-audio-capturer" -codec:a aac -b:a 128k -ac 2 -ar 48000 -f mpegts udp://127.0.0.1:1111
    
ffplay -codec:a aac -b:a 128k -ar 48000 -ac 2 udp://127.0.0.1:1111

    opus codec working

    ffmpeg -f dshow -i audio="virtual-audio-capturer" -codec:a libopus -b:a 128k -ac 2 -ar 48000 -f mpegts udp://127.0.0.1:1111
    
ffplay -codec:a libopus -b:a 128k -ar 48000 -ac 2 udp://127.0.0.1:1111

    mp3 working

    ffmpeg -f dshow -i audio="virtual-audio-capturer" -codec:a mp3 -b:a 128k -ac 2 -ar 48000 -f mpegts udp://127.0.0.1:1111
    
ffplay -codec:a mp3 -b:a 128k -ar 48000 -ac 2 udp://127.0.0.1:1111

    why libvorbis not working?

    transport success, but can not play, i think.

    // not woring ffplay displayed log
    
ffplay.exe -loglevel debug -codec:a vorbis -b:a 128k -ar 48000 -ac 2 -sync audio -i udp://127.0.0.1:1111

  • FFMPEG/AVCONV Video flipping is taking long time, How can we reduce the process time?

    10 July 2014, by Prasanth P

    I am trying to flip video using FFMPEG/AVCONV on Ubuntu. When it flips 1 minute video, it takes 12 to 40 seconds for processing and conversion.

    ffmpeg is deprecated and avconv is being using instead.

    Video file size : 7mb, Duration : 1 minute

    avconv -i 1_1.mp4 -c:v libx264 -c:a copy -vf "vflip" conv.mp4

    and the result is:
