    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • why would ffmpeg rotate 2nd video on concatenation when I don't want it to or seemingly ask for it ?

    10 janvier 2023, par Pompey Magnus

    here is the command I run :

    


    ffmpeg -f concat -an -i ./files.txt ztestout.mp4


    


    I have about 5 videos, but just to test I did with two.
the 2nd video gets flipped upside down, even though opening each video in VLC opens and plays them correctly.

    


    Any ideas why it would do that ? Is the metadata wrong in the video ? I took all the videos I'm trying to concat with the same android phone.

    


    output below, and I noticed its says rotation zero degrees :

  • How can I stream mjpeg file as rtsp

    24 août 2013, par Ilya Yevlampiev

    We have an mjpeg video, obtained from the webcam and stored into *.avi file, still encoded as mjpeg.

    We need to restream this file as rtsp (and stil preserve the mjpeg there, i.e. no decoding). The goal is to emulate the webcam this video was obtained from for the software that processes the video. The file can be open with vlc/ffplay with no problems. The ffmpeg behaves like it is streaming it, however, ffplay/vlc can't open this stream.

    We tried to stream if with gstreamer.

    1) we fount no free rtsp sink element for gstreamer pipeline. So, is there a free analogue for rtspsink to launch this pipeline with gst-launch ? we need and only cast, so we don't need so advanced element as rtspsink is.

    2) we also tried to build own simple rtsp server as described in http://weeklybuild.com/2013/01/creating-an-rtsp-stream-with-gstreamer/

    replacing videotestsrc with filesrc ; but what kind of elements we should use there ? usage of an only filesrc doesn't help ; we get the same problem as if we stream with ffmpeg. But what kind of lements we need there, if we dont' wan to decode/encode it, just to stream the file (to reproduce the thing what the webcam actually does).
