  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
    Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible.

  • Using VLC for MPEG2 video encoding with I-frames only

    4 mars 2014, par user3319428

    Is there a VLC option to be able to do MPEG2 video encoding with I-frames only (not P and B) ? I would like to be able to transcode from one file format (such as AVI) to another with MPEG2 transcoding done so that only I-frames are encoded. Later this file will be streamed to an MPEG2 decoder, and I would like to have this feature to simplify the decoder (due to hardware/software restrictions).

    It looks like the ffmpeg module in VLC may be able to do this, but I am not sure of the options for it. I tried to use the keyint=0 option (where the key frames are considered to be I-frames), but it did not seem to work, as the same output file size resulted with or without this option.

    What I really want is for the output file to be in transport stream format too.

    I am using VLC ver. 2.1.3 under Windows 7.

    Thanks in advance for any help you can offer.

  • screen mess when change video on rtmp

    16 mars 2014, par dingyaguang117

    1. when I use "ffmpeg -i" to probe video info， the infos below will be shown (take 2 examples)

      Stream #0:0 : Video : h264 (High), yuv420p, 600x352, 281 kb/s, 29.97 tbr, 1k tbn, 59.94 tbc
Stream #0:0(und) : Video : h264 (Main) (avc1 / 0x31637661), yuv420p, 640x480 [SAR 1:1 DAR 4:3], 532 kb/s, 25 fps, 25 tbr, 25k tbn, 50 tbc

      What does the "avc1" mean？why the first doesn't shown ?

      Will it be "screen mess","no sound" or "no image" when switch the video that is publishing to rtmp server if the contiguous video encode by different codec ?

    2. How to switch video publishing to rtmp smoothly ？
      I use nginx-rtmp-module，set "live on"，and use "ffmpeg -re" to publish video.
      My method to switch video is to "pkill ffmpeg", and start another "ffmpeg -re" process.
      If the contiguous videos encode by different codec，it maybe "screen mess","no sound" or "no image". What can I do to solve it ?

    3. Are there any experiences(about tools,switch videos,how to choose encoding) when doing live video ?
