  • 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 camera + mic and encode to h264/aac on macOS

    16 décembre 2018, par Flock Dawson

    I’m having trouble capturing and encoding audio+video on-the-fly on macOS.

    I tried two options :

    1. ffmpeg

      ffmpeg -threads 0 -f avfoundation -s 1920x1080 -framerate 25 -I 0:0 -async 441 -c:v libx264 -preset medium -pix_fmt yuv420p -crf 22 -c:a libfdk_aac -aq 95 -y

    2. gstreamer

      gst-launch-1.0 -ve avfvideosrc device-index=0 ! video/x-raw,width=1920,height=1080,framerate=25/1 ! vtenc_h264 ! queue ! mp4mux name=mux ! filesink location=out.mp4  osxaudiosrc device=0 ! audio/x-raw ! faac midside=false ! queue ! mux.

    The ffmpeg option works, but only for lower resolutions. With higher resolutions, the Mac mini (2018 gen) can’t do the heavy lifting. I think because I installed ffmpeg with brew, so it wasn’t compiled on my machine, meaning it doesn’t use the h264 hardware encoder in the Mac ?

    The gstreamer option works as well, but there’s a slight audio/video sync issue (audio is 100ms ahead of the video). I can’t seem to add delay to the GStreamer queue (it ignores it) :

    queue max-size-buffers=0 max-size-time=0 max-size-bytes=0 min-threshold-time=100000000

    Anyone who has any experience with this ? Thanks !

  • qsv : Make the hevc idr_interval consistent with the h264 one

    qsv : Make the hevc idr_interval consistent with the h264 one

    According to the MediaSDK documentation the idr_interval value has
    
a different meaning depending on the codec :
    

        0 in H264 means make every I-frame IDR, in HEVC it means to have
    
    it only at the beginning.
    

        1 in H264 means every other I-frame is not-IDR, in HEVC it means
    
    that every I-frame is IDR.
    

    Keep the behaviour consistent between the two encoders by increasing
    
by 1 internally the idr_interval value for HEVC.

  • avformat/utils : Move the reference to the packet list

    20 septembre 2019, par Andreas Rheinhardt
    avformat/utils : Move the reference to the packet list

    Up until now, ff_packet_list_put had a flaw : When it moved a packet to
    
the list (meaning, when it ought to move the reference to the packet
    
list instead of creating a new one via av_packet_ref), it did not reset
    
the original packet, confusing the ownership of the data in the packet.
    
This has been done because some callers of this function were not
    
compatible with resetting the packet.
    

    This commit changes these callers and fixes this flaw. In order to
    
indicate that the ownership of the packet has moved to the packet list,
    
pointers to constant AVPackets are used whenever the target of the
    
pointer might already be owned by the packet list.
