  • 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.

  • Ffmpeg hls live stream video freezes for a second but audio continues and video catches up

    13 décembre 2022, par Bluchip Studio

    I am using the latest version of ffmpeg to create a hls live stream todo this i am using the following command

    


    /root/ffmpeg -y -loglevel debug -threads 0 -probesize 512000 -analyzeduration 512000 -user_agent "Chrome/98.0.4758.102" -i https://example.com/input.m3u8 -c:v copy -c:a copy -async 1 -tune zerolatency -fflags +genpts -hls_init_time 2.002 -hls_time 2.002 -hls_list_size 20 -hls_flags delete_segments+append_list -hls_segment_type mpegts -hls_segment_filename "/var/www/html/hls/segment_%05d.ts" -f hls "/var/www/html/hls/playlist.m3u8"


    


    I initially tried using fmp4 but i noticed the video would lag behind major and the audio would end up well ahead so i switched to mpegts

    


    i managed to fix the audio issue here using -async 1 on fmp4 this made no diffrence now i have a small issue where my stream will open and play but the video will freez every few seconds while the audio continues and then the video will jump to catch back up and continue then it will do it again and again and again

    


    dose anyone know what may be causing this issue i tried swapping to x264 in stead of copying the video stream and using force key frames to set a key frame every 2 seconds but this resulted in well the same issue if not a little worse

    


    i kind of expected the stream to play perfect with the settings i have and with the logs set to debug i cant see any errors at all

    


  • Stream real-time video flux in HTML video tag

    26 septembre 2018, par c.censier

    I want to stream a real-time video flux that come from udp into a HTML video tag.
    I made some research but I got a lot of informations and I struggle to have a clear overview of what I can do and what I can’t.

    The video flux use H.264 and AAC codecs, MP4 container and has a 3840x2160 (4K) resolution. I’d like to play it on Chrome (latest version).

    As I understand from now, HTML video tag can natively read H.264/AAC videos. I made it work with the video direclty on my server (I’m using Meteor JS + React).

    I learnt to use FFmpeg to stream an udp flux read by VLC player, and then I used FFserver (I know it’s deprecated) to create an HTTP flux also read by VLC but not by the HTML video tag.

    So... my question is : is HTML video can natively read video stream from HTTP ?

    I’ve seen a lot of discussions about HLS and DASH, but I didn’t understand if (and why) they’re mandatory.

    I read a post about someone creating a HLS m3u8 using only FFmpeg, is it a viable solution ?

    FFserver configuration

    HTTPPort                        8090

  VideoBufferSize               20000      // Not sure either
    
  AVOptionVideo                 flags +global_header
    
</stream>

    I had to specify QMin and QMax to avoid error message but I don’t really understand what is it.

    FFmpeg command line

    ffmpeg -re -i bbb_sunflower_2160p_30fps_normal.mp4 -strict -2 -r 30 -vcodec libx264 http://localhost:8090/feed.ffm

    This work with VLC. I’m working with a file on my computer before moving to an udp stream.
