  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • 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 ?

  • Pulseaudio record multiple xfbv screens with python

    10 octobre 2020, par Eric Lagarda

    I’m trying to do something complicated and I need some help.

    


    I’m able to record a session (video and audio) with python using xvfb and ffmpeg.

    


    I just want to visit a page using selenium and record the video and audio. It’s working but when I try to run multiple instances, the audio is mixing between records.

    


    How can achieve that ? I’m using pulseaudio. I know that with alsa you can set like a interface per instance, but I don’t know how to do it.

    


    Thanks for you support and comments.

    hwcontext_vulkan : expose enabled device and instance extensions

    This solves a huge oversight - it lets users reliably use their own
    
AVVulkanDeviceContext. Otherwise, the extensions supplied and enabled
    
are not discoverable by anything outside of hwcontext_vulkan.
    
Also clarifies that any user-supplied VkInstance must be at least 1.1.
