  • 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.

  • Node.js asynchronous video conversion slow

    9 December 2016, by lukstei

    I wrote a little website/service, which can download a video from a website (currently Youtube) and converts it on the fly to an mp3 file and sends this file back as the response.

    For example, you when you request http://localhost:8000/v=http://www.youtube.com/watch?v=HhoewflkQu0, then it will download this video and response the audio layer encoded in MP3.

    This all works very well, my problem is that this is very slow and I can’t figure out why.

    Simplified the script behaves like this:

    Download the video and write it to the stdin of ffmpeg, and the stdout goes to the response.
    Video (MP4, FLV) -> FFMPEG -> MP3

    I used curl to figure out how fast the script is:

    $ curl http://localhost:8000/v=http://www.youtube.com/watch?v=HhoewflkQu0

    I get only about 5-10k.

    So why is this so slow?

    1. The server, from which I am downloading the video is slow.
    2. The conversion is slow (because of a slow CPU).
    3. The data transfer between node.js -> FFMPEG is slow.

    I tried to download the video in a normal download manager, and i got about 320k, which is my normal download speed, so the first point isn’t the bottleneck.

    To point 2 and 3, I tried to write a local file to the stdin, and I got about 600k so that isn’t it either.

    So why is my script so slow, and what can I do to make it faster?

  • RTSP Client for H264 Audio/Video Stream

    1 April 2015, by Jean-Philippe Encausse

    I’m looking for a simple way to get data of an IP Camera RTSP Stream (using H264 Audio/Video) and get on the other side

    • a frame by frame byte[]
    • a stream of the audio

    After many research

    • EmguCV Capture seems hanging forever (no answer from forum)
    • There is many (too big) RTSP Server few decode H264
    • There is "slow" ffmpeg wrapper
    • There is some managed DirectShow wrapper

    So I don’t know where to go ? And how to do this ?

    It seems iSpyCamera is doing the job but it’s a big project not a little library to query ip cameras.

  • FFMPEG drops every odd frame

    28 March 2016, by Oleksiy Druzhynin

    At running of

    ffmpeg -i /usr/local/Videos/Ads/Samples/DX/DXd_src.ts -vf drawtext=fontfile=/usr/share/fonts/truetype/ubuntu-font-family/UbuntuMono-R.ttf:text=’%pict_type %pts:hms %pts:raw %eif:n:u’: fontcolor=white@0.8:fontsize=40:x=7:y=200:box=1:boxcolor=black@0.8 -copyts -muxdelay 0 -muxpreload 0 -copytb 1 -vsync 0 -xerror /usr/local/Videos/Ads/Samples/DX/DXd.ts

    FFMPEG removes every odd frame in for some set of video. I couldn’t understand why?
