  • 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.

  • Using ffmpeg to encode web dash and audio drift

    1er octobre 2016, par John Joske

    I’m trying to use ffmpeg to create webm-dash encoded files from a usb web cam. Adapted from this example http://wiki.webmproject.org/adaptive-streaming/instructions-to-do-webm-live-streaming-via-dash

    I have managed to get something nearly works with the following command :

    ffmpeg -f video4linux2 -framerate 30 -s 640x360 -i /dev/video0
    -thread_queue_size 512 -f alsa -ar 44100 -ac 2 -i hw:2 -map 0:0 -pix_fmt yuv420p -c:v libvpx-vp9 -s 640x360 -keyint_min 60 -g 60 -speed 6 -tile-columns 4 -frame-parallel
    1 -threads 8 -static-thresh 0 -max-intra-rate 300 -deadline realtime
    -lag-in-frames 0 -error-resilient 1 -f webm_chunk -header video_360.hdr" -chunk_start_index 1 video_360_%d.chk -map 1:0 -c:a libvorbis -b:a 128k -ar 44100
    -f webm_chunk -copytb 1 -audio_chunk_duration 2000 -header video_171.hdr -chunk_start_index 1 video_171_%d.chk

    However over a period of time the audio chunks slowly get behind the video chunks, can anyone suggest a way to ensure they stay the same.

  • Compile FFmpeg with openssl for macOS

    23 juin 2017, par H. Wilson

    Hi I would like to ask how to compile ffmpeg with openssl for macOS.

    When I type https in ffmpeg to download / encode webstream from the website I always get an error

    "https protocol not found, recompile FFmpeg with openssl, guntls. or securetransport enabled"

    whilst http does work (some websites didn’t allow http as I got an error "HTTP error 403 Forbidden though)

    https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX

    I have read the link above but I am unsure about the process as I don’t use homebrew to install ffmpeg but built myself.

    I am the very beginner using ffmpeg and any help would be appreciated..
    I hope somebody could show me its process to compile ffmpeg with openssl.

    For further advice, I am wondering if the function of ffmpeg I built myself is same as the static one here : ttps ://ffmpeg.zeranoe.com/builds/

    I built ffmpeg for mac by this website : http://ericholsinger.com/install-ffmpeg-on-a-mac

    Thanks in advance
