  • 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" (...)

  • Why does iftop show no bandwidth from a multicast IP but tcpdump does ? ffmpeg also cannot capture from the multicast

    22 mars 2018, par Lenny

    I ran into a puzzling problem when trying to receive a multicast IP (of a video from 239.193.140.11:1234).

    When $tcpdump dst 239.193.140.11 -w capturedData.pcap, the packets are captured correctly.

    eg, 11:05:25.357138 IP 192.168.34.34.46192 > 239.193.140.11.1234 : UDP, length 1328

    This means that my machine is receiving the multicast IP packets.

    However, when $iftop -i any is run, iftop doesn’t show any bandwidth from 239.193.140.11. Furthermore, when I try to capture the multicast packets with ffmpeg : $ffmpeg -i udp://239.193.140.11:1234?localaddr=192.168.34.34, no packets are captured.

    Why is there a discrepancy between what tcpdump and iftop shows, and how to resolve it so that ffmpeg can capture correctly ?

  • compile the ffmpeg3.3 for Mac OS show ERROR : libmp3lame >= 3.98.3 not found

    4 mars 2018, par MR.PJ

    I use my mac to compile the ffmpeg3.3 for Mac OS according to https://trac.ffmpeg.org/wiki/CompilationGuide/macOS.I tried the first(which through Homebrew) and third(which builds it yourself) method,the first method is ok.

    But the third, compiling FFmpeg myself and Installing dependencies with Homebrew.I don’t know the meaning of this sentence enter image description here

    after this step :

    ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass \
    --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame \
    --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-libopus --enable-libxvid \
    --samples=fate-suite/

    terminal show :

    RROR: libmp3lame >= 3.98.3 not found

    when I use locate libmp3lame.a,it is at ’/usr/local/Cellar/lame/3.99.5/lib/libmp3lame.a’.

    I also try --enable-libmp3lame --extra-ldflags=-L/usr/local/lib to solve,but it is no effect.

    How to solve thisERROR: libmp3lame >= 3.98.3 not found

  • Streaming UDP packets to two different ports (for video and audio). Video works fine, but the audio does not show

    8 avril 2018, par Winston Chen

    I am taking a rtsp stream, split the video and audio out, and stream them to two different ports respectively using gstreamer so that my ffserver would be able to display the stream on my browser.

    My gstreamer pipeline :

    gst-launch-1.0 -v rtspsrc location=rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov latency=300 timeout=0 drop-on-latency=true rtp-blocksize=4096 name=rtsp_source ! \
    
  queue ! capsfilter caps="application/x-rtp,media=video" ! rtph264depay ! h264parse ! rtph264pay config-interval=1 pt=96 ! udpsink host=127.0.0.1 port=9527 rtsp_source. ! \
    
  queue ! rtpmp4apay pt=97 ! udpsink host=127.0.0.1 port=9327

    Here comes the sdp and my ffmpeg commnad :

    m=video 9527 RTP/AVP 96
    
a=rtpmap:96 H264/90000
    
c=IN IP4 127.0.0.1
    

    
m=audio 9327 RTP/AVP 97
    
a=rtpmap:97 mpeg4-generic/48000/6
    
c=IN IP4 127.0.0.1

    ffmpeg -protocol_whitelist "file,tcp,rtp,udp" -i ~/test.sdp -max_muxing_queue_size 1024 http://localhost:8090/feed1.ffm

    And finally, this is my ffserver config (the important part) :

    <feed>               # This is the input feed where FFmpeg will send
    
   File ./feed1.ffm            # video stream.
    
   FileMaxSize 1GB             # Maximum file size for buffering video
    
   ACL allow 127.0.0.1         # Allowed IPs
    
</feed>
    

    
<stream>              # Output stream URL definition
    
   Feed feed1.ffm              # Feed from which to receive video
    
   Format webm
    

    
   # NoDefaults
    
   # NoAudio
    

    
   # Audio settings
    
   AudioCodec vorbis
    
   AudioBitRate 64             # Audio bitrate
    

    
   # Video settings
    
   VideoCodec libvpx
    
   VideoSize 240x160           # Video resolution
    
   VideoFrameRate 10           # Video FPS
    
   AVOptionVideo flags +global_header  # Parameters passed to encoder
    
                                       # (same as ffmpeg command-line parameters)
    

    
   PreRoll 0
    
   StartSendOnKey
    
   VideoGopSize 12
    
   VideoBitRate 256
    
</stream>

    The thing is that if I take away the audio part and apply NoAudio, the video streams fine. However, I could not get the audio to work. Am I doing anything wrong ?
