  • 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" (...)

  • Is there a MS-DRM client library for linux ?

    19 juin 2016, par qrtt1

    I have used the libraries (libavformat and libavcodec) to decode some MMS streaming urls. But some of them are protected by DRM. When I try to decode them, the library will warn about it

    In libavformat/asfdec.c :

    if (!s->keylen) {
    
    if (!guidcmp(&g, &ff_asf_content_encryption)) {
    
        av_log(s, AV_LOG_WARNING, "DRM protected stream detected, decoding will likely fail!\n");
    
    } else if (!guidcmp(&g, &ff_asf_ext_content_encryption)) {
    
        av_log(s, AV_LOG_WARNING, "Ext DRM protected stream detected, decoding will likely fail!\n");
    
    } else if (!guidcmp(&g, &ff_asf_digital_signature)) {
    
        av_log(s, AV_LOG_WARNING, "Digital signature detected, decoding will likely fail!\n");
    
    }
    
}

    The variable s is the struct AVFormatContext. My question is where to get the key ? It seems to decode it with a DRM key.

    I look the ASF Spec, and try to patch asfdec.c. Now, I have the acquiring license URL and key id. The problem can rewrite as ’Is there a MS-DRM client library for linux ?’ (old : How to decode a MMS streaming url with DRM by ffmpeg ?)

    Is it possible to use the license url and key id to get content key ?

  • Any equivalent to '-c:v copy' for changing container of webm to mp4 video client-side in JS ?

    15 mars 2020, par programmingisphun

    Exploring the Mediarecorder API and really hope to get an mp4 output instead of webm. Prefer to stay client-side to reduce server resources and ffmpeg.js at 17mb doesn’t seem viable for online use.

    Discovered that one can create (Chrome/Firefox) a webm/h.264, which converts without re-encoding to an mp4 using FFMPEG. The resulting file opens fine in Quicktime MacOS (snippet source) :
    ffmpeg -i _inputfile_.webm -c:v copy _outputfile_.mp4

    Whereas this clever hack works to display the video maybe as an mp4 in the browser, but the downloaded file won’t open in Quicktime (just VLC, same for webm) :

    new Blob(recordedBlobs, {type: 'video/mp4'});
    
video.src = window.URL.createObjectURL(superBuffer);

    Therefore, wondering if there’s another JS hack to do what FFMPEG’s -c:v copy does, but to the blob bytes of the MediaRecorder’s recordedBlobs and give it the same mp4 container that’s accepted by Quicktime/etc ?

    Pastebin of current setup
