  • 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. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • TCP connection refused with FFMPEG

    2 février 2017, par Samul

    OFFICIAL EDIT :

    I thank you so much for your help but I am still encountering problems.

    My ffserver.conf file is like this :

    # Port on which the server is listening. You must select a different
    
# port from your standard HTTP web server if it is running on the same
    
# computer.
    
HTTPPort 8090
    

    
# Address on which the server is bound. Only useful if you have
    
# several network interfaces.
    
HTTPBindAddress 0.0.0.0
    

    
# Number of simultaneous HTTP connections that can be handled. It has
    
# to be defined *before* the MaxClients parameter, since it defines the
    
# MaxClients maximum limit.
    
MaxHTTPConnections 2000
    

    
# Number of simultaneous requests that can be handled. Since FFServer
    
# is very fast, it is more likely that you will want to leave this high
    
# and use MaxBandwidth, below.
    
MaxClients 1000
    

    
# This the maximum amount of kbit/sec that you are prepared to
    
# consume when streaming to clients.
    
MaxBandwidth 1000
    

    
# Access log file (uses standard Apache log file format)

# Definition of the live feeds. Each live feed contains one video
    
# and/or audio sequence coming from an ffmpeg encoder or another
    
# ffserver. This sequence may be encoded simultaneously with several
    
# codecs at several resolutions.
    

    
<feed>
    

    
# You must use 'ffmpeg' to send a live feed to ffserver. In this
    
# example, you can type:
    
#
    
# ffmpeg http://localhost:8090/feed1.ffm
    

    
# ffserver can also do time shifting. It means that it can stream any
    
# previously recorded live stream. The request should contain:
    
# "http://xxxx?date=[YYYY-MM-DDT][[HH:]MM:]SS[.m...]".You must specify
    
# a path where the feed is stored on disk. You also specify the
    
# maximum size of the feed, where zero means unlimited. Default:
    
# File=/tmp/feed_name.ffm FileMaxSize=5M
    
File /tmp/feed1.ffm
    
FileMaxSize 200K
    

    
# You could specify
    
# ReadOnlyFile /saved/specialvideo.ffm
    
# This marks the file as readonly and it will not be deleted or updated.
    

    
# Specify launch in order to start ffmpeg automatically.
    
# First ffmpeg must be defined with an appropriate path if needed,
    
# after that options can follow, but avoid adding the http:// field
    
#Launch ffmpeg
    

    
# Only allow connections from localhost to the feed.

    No error message and everything looks fine.

  • ffmpeg mkv to mp4 including subtitles

    1er février 2017, par user3677559

    Want to convert mkv files to mp4 (h264, mp3 and subtitles). I checked the video files with ffprobe. For the output

    Stream #0:2(ger) : Subtitle : dvb_subtitle (default)

    The subtitles are included in the converted video with following ffmpeg command.

    ffmpeg -i movie.mkv -c:v libx264 -c:a libmp3lame  -b:a 320k -c:s dvd_subtitle  converted.mp4

    But for the output :

    Stream #0:3(ger) : Subtitle : subrip (default)

    The command isn’t working. There is no error message and the resulting video includes a subtitle stream, but no subtitles are showed. I tried also with the subtitle encoding mov_text and copy, but no luck. Following the output from console :

  • RTP packets detected as UDP

    28 février 2017, par user3172852

    Here is what I am trying to do :

    WebRTC endpoint > RTP Endpoint > ffmpeg > RTMP server.

    This is what my SDP file looks like.

    var cm_offer = "v=0\n" +
    
              "o=- 3641290734 3641290734 IN IP4 127.0.0.1\n" +
    
              "s=nginx\n" +
    
              "c=IN IP4 127.0.0.1\n" +
    
              "t=0 0\n" +
    
              "m=audio 60820 RTP/AVP 0\n" +
    
              "a=rtpmap:0 PCMU/8000\n" +
    
              "a=recvonly\n" +
    
              "m=video 59618 RTP/AVP 101\n" +
    
              "a=rtpmap:101 H264/90000\n" +
    
              "a=recvonly\n";

    What’s happening is that wireshark can detect the incoming packets at port 59618, but not as RTP packets but UDP packets. I am trying to capture the packets using ffmpeg with the following command :

    ubuntu@ip-132-31-40-100:~$ ffmpeg -i udp://127.0.0.1:59618 -vcodec copy stream.mp4

    All I get is a blinking cursor and The stream.mp4 file is not written to disk after I exit (ctrl+c).

    So can you help me figure out :

    1. why wireshark cannot detect the packets as RTP (I suspect it has something to do with SDP)
    2. How to handle SDP answer when the RTP endpoint is pushing to ffmpeg which doesn’t send an answer back.

    Here is the entire code (hello world tutorial modified)
