    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • ffmpeg cache whole video stream and save

    19 juillet 2016, par Luiz

    I have a security DVR that can stream a video recording using the RTSP protocol. I can record the playback using ffmpeg and save it to a file, but for a 20 min video, I have to watch the video to save or wait the whole playback time.
    I’m using :

    ffmpeg -i "rtsp://mystream" -r 15 -acodec copy -vcodec copy myvideo.mp4

    to do this

    Is there any way to buffer the whole stream and just save it to a file using ffmpeg, without the need to watch or wait the whole 20 minutes playback ? I don’t need to reencode anything since the stream video format is good enough for me.

    Thanks in advance

  • Streaming protocol relay without involving codec

    4 décembre 2015, par kiran_g

    I am trying to use libav to relay an RTSP stream. It involves PULLing the stream from an IP camera and then PUSHing to wowza.

    The video encoding in the IP camera stream is h264. To enable h264 in my libav application I need to enable x264. But as x264 is GPL, it will not work with my business plan.

    My questions is whether libav (ffmpeg) can be made to work like a dumb relay which is encoding-agnostic ? so that I dont need to integrate x264 with ffmpeg.

    This SO post says that I can use the "copy" argument, but does that allow me to exclude x264 ?

    BTW, is x264 actually needed by ffmpeg for decoding h264 ? Is x264 only used in encoding ?

    See here for my current code.
