  • 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" (...)

  • Should libavcodec handle non-packed/non-byte-aligned mp3 packets ?

    27 août 2015, par Rhythmic Fistman

    I’m transcoding shoutcast streams using libavcodec and I noticed that during the day I get a few 10s’ of packets that it cannot decode without some help :

    1. Leading zero bytes before a packet sync word, e.g. 0x0000fffa

    2. non-byte aligned syncword, e.g 0x82a0fffa

    In the first case I have to toss out the zero bytes and in the second I have to shift the data up by an odd number of nibbles.

    I don’t have a watertight knowledge of the mp3 spec (is there one ?), but my impression was that the packet format was a bit oriented, not byte, so both types of packets look right to me.

    So who is in the wrong here ?

    Is it libavcodec for not parsing valid packets ?

    Or the stream encoder for producing non-standard packets ?

  • subprocess.Popen crashes when run in background

    17 mars 2016, par user2810298

    In a program I’m working with right now, I try to check for the version of FFMPEG that is installed on the users machine. This works perfectly fine by using subprocess.Popen when run in the foreground OR when run in a detached screen.

    However, when you run it in the background without screen (e.g. COMMAND &> /dev/null &) this process crashes the program. (see below) I’ve seen some people having similar issues on the web, but I still can’t seem to fix this...

    I’ve Any ideas ?

    version_ffmpeg = subprocess.Popen(["ffmpeg","-version"],stdout=subprocess.PIPE,stderr=None)
    

    
f_out = version_ffmpeg.communicate()
    
(then...)
    
if f_out --> 3rd word contains --> etc.
