  • 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" (...)

  • How To Get FFMPEG To Continuously Overwrite/Append Audio File ?

    28 octobre 2018, par GPinskiy

    I installed an external audio card onto my Raspberry Pi 3 and I want to Chromecast the recorded audio. I have set up a Node.js server to cast things and have set up the sound card using alsamixer. I can correctly hear the line-in on the headphones when I use the command arecord -D hw:0,0 -r 48000 -f S32_LE -c 2 | aplay -D dmix:CARD=audioinjectorpi,DEV=0 -r 48000 -f S32_LE -c 2 to simulate pass-through.

    The last step is to actually expose this stream in a way that the Chromecast can access. The Chromecast can’t use a RDP stream or anything similar, only files. So I thought that I could get away with having FFMPEG create an mp3 file that it continuously appends to while dropping the last x seconds so that the overall length of the mp3 file is only like 20 seconds and having a local web server that the Chromecast can get that file from.

    I see that there is a way to automatically segment in FFMPEG but that create a bunch of separate 20 sec files rather than a single file that is 20 secs. What would be the correct way of doing this ?
