  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Capture raw video byte stream for real time transcoding

    9 septembre 2012, par user1145905

    I would like to achieve the following :

    Set up a proxy server to handle video requests by clients (for now, say all video requests from any Android video client) from a remote video server like YouTube, Vimeo, etc. I don't have access to the video files being requested, hence the need for a proxy server. I have settled for Squid. This proxy should process the video signal/stream being passed from the remote server before relaying it back to the requesting client.

    To achieve the above, I would either

    1. Need to figure out the precise location (URL) of the video resource being requested, download it really fast, and modify it as I want before HTTP streaming it back to the client as the transcoding continues (simultaneously, with some latency)

    2. Access the raw byte stream, pipe it into a transcoder (I'm thinking ffmpeg) and proceed with the streaming to client (also with some expected latency).

    Option #2 seems tricky to do but lends more flexibility to the kind of transcoding I would like to perform. I would have to actually handle raw data/packets, but I don't know if ffmpeg takes such input.

    In short, I'm looking for a solution to implement real-time transcoding of videos that I do not have direct access to from my proxy. Any suggestions on the tools or approaches I could use ? I have also read about Gstreamer (but could not tell if it's applicable to my situation), and MPlayer/MEncoder.

    And finally, a rather specific question : Are there any tools out there that, given a YouTube video URL, can download the byte stream for further processing ? That is, something similar to the Chrome YouTube downloader but one that can be integrated with a server-side script ?

    Thanks for any pointers/suggestions !

  • Using chunks of MP4 file for thumbnails

    20 janvier 2014, par Moritz Mahringer

    I want to extract single frames (as thumbs) from videos, without having to download the full video file. I would like to just read the mp4 header (the info should be in the moov atom) and then download the required byte ranges. Afaik thats what browsers (HTML5 video) do when you skip to an unbuffered part

    I already looked at : How can HTML5 video's byte-range requests (pseudo-streaming) work ? but i can't figure out how to use it with ffmpeg for example.

    Thanks a lot !
