  • 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 (...)

  • 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).

  • convert mp4 to m4a using ffmpeg in android

    30 novembre 2017, par abdulrahman

    I’m trying to add the ability to compress video files in my project. However, I tried to extract the Audio from the original video file using FFMPEG Library before compressing it. The command line was

    -i video.mp4 -c:a aac -b:a 160k target.m4a

    After the encoding was done I noticed that the output is still a video file but with a difference in the size. This brought two questions to me and I would like to know their answers.

    1 - can the ".m4a" file be considered as a video file ?

    2 - can I use this command line to compress video files ?

    Best regards
