  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • FFMPEG : Youtube streaming issues

    23 février 2019, par Alex Paramonov

    I am trying to make a reliable stream from my Icecast/Shoutcast servers to Youtube live.
    The command that I use is :

    /usr/bin/ffmpeg -re -loop 1 -framerate 1 -i /var/users/youtube_stream/DJ-philadelphia_jO46wsH.jpg -i http://127.0.0.1:4700/radio -c:v libx264 -preset ultrafast -maxrate 2048k -bufsize 2048k -c:a copy -ab 128k -s 1920x1080 -rtmp_live live -f flv rtmp://a.rtmp.youtube.com/live2/k123 -nostats

    The stream starts running but suddenly stops at random times with the output similar to this :

    av_interleaved_write_frame(): Broken pipe
    
[flv @ 0x5641e04db260] Failed to update header with correct duration.
    
[flv @ 0x5641e04db260] Failed to update header with correct filesize.
    
Error writing trailer of rtmp://a.rtmp.youtube.com/live2/123: Broken pipe

Conversion failed!
    
99%
    
Exiting normally, received signal 15.

    I can’t say exactly why is this happening and maybe there is a way to fix it, but to mee it looks like ffmpeg can not send or convert some frame and it breaks the entire process, so I started digging the docs and found a fifo format that has reconnection options in case of failure.
    So my new command is :

    /usr/bin/ffmpeg -re -loop 1 -framerate 1 -i /var/users/youtube_stream/DJ-philadelphia_jO46wsH.jpg -i http://127.0.0.1:4700/radio -c:v libx264 -preset ultrafast -maxrate 2048k -bufsize 2048k -c:a copy -ab 128k -s 1920x1080 -rtmp_live live -f fifo -fifo_format flv -map 0:v -map 1:a -drop_pkts_on_overflow 1 -attempt_recovery 1 -recovery_wait_time 1 rtmp://a.rtmp.youtube.com/live2/123 -nostats

    With this command Youtube starts complaining about video resolution saying that 65535x65535 is not supported, value 65535 looks like something is not initialized properly. Please note that I have explicitly set the resolution with -s 1920x1080.

    The output from FLV and FIFO formats looks quite similar.

    you can see the input streams, output, mapping - all fine except one line that is missing with fifo format :

    [libx264 @ 0x563bdde386a0] 264 - core 152 r2854 e9a5903 - H.264/MPEG-4 AVC codec - Copyleft 2003-2017 - http://www.videolan.org/x264.html ...

    Seems like video codec is not completely initialized and does not start with when using fifo format.

    So my questions are :

    1. is there a way to create a reliable stream with ffmpeg w/o using
      fifo format ?
    2. if fifo format is mandatory in this case, what’s wrong with my
      video codec ?

  • Stream from MP4 file over RTSP with ffserver

    25 octobre 2019, par sirlion

    I’m trying to stream a mp4 file over RTSP using ffserver with no luck so far. I just want to stream directly from the file, without feeding from ffmpeg (no transcoding involved). But I’ve made it work with mpg video.

    Here is my ffserver config file :

    Port 8090
    
BindAddress 0.0.0.0
    
MaxHTTPConnections 2000
    
MaxClients 1000
    
MaxBandwidth 500000
    
CustomLog -

    Format rtp

</stream>
    
<stream>
    
    Format rtp
    
    File "/home/g/video.mp4"
    
</stream>

    When I launch ffserver, everything seems fine based on the log output :

Segmentation fault (core dumped)

    I don’t really know what I could be missing. I’ve just read in the official doc that streaming from a file is kind of broken. Since I don’t really know if that’s up to date, I decided to give it a try here.

    Any help or suggestions ? Alternatives ?

    &#xA;

    is that the problem ?

    &#xA;

    i have also tried with filter complex script, but the same error appears.

    &#xA;

    thank you so much

    &#xA;

    many greets iceget

    &#xA;

    if i use a shorter time (about 10 seconds) then its working fine. but when i add 100 or 256 seconds, then i getting only a 1kb mp4 file.

    &#xA;

    thank you
