  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • FFMPEG - Stream to RTMP output and save to MP4 at same time - with reconnect

    13 janvier 2021, par Matt

    I'm trying to setup a pipeline where I can take an input and save to MP4 whilst at the same time streaming to an RTMP server.

    



    So far I've been able to use a tee filter to achieve this and also using the onfail=ignore to make sure the pipeline stays up in the event of the RTMP/Recording failing.

    



    Which is great !

    



    However, I don't want the RTMP to just give up if it were to drop or be disconnected, I'd like it to keep attempting to reconnect and resume the stream.

    



    I don't think FFMPEG has something like this, so I'd need to write it in a bash script or something that keeps restarting the process in the event of a drop.

    



    I just have no idea how to achieve this !

    



    Has anybody got any ideas or tackled this before ?

    



    Thanks,

  • How to get raw frame data from AVFrame.data[] and AVFrame.linesize[] without specifying the pixel format ?

    25 janvier 2016, par vivienlwt

    I get the general idea that the frame.data[] is interpreted depending on which pixel format is the video (RGB or YUV). But is there any general way to get all the pixel data from the frame ? I just want to compute the hash of the frame data, without interpret it to display the image.

    According to AVFrame.h :

    uint8_t* AVFrame::data[AV_NUM_DATA_POINTERS]

    pointer to the picture/channel planes.

    int AVFrame::linesize[AV_NUM_DATA_POINTERS]

    For video, size in bytes of each picture line.

    Does this mean that if I just extract from data[i] for linesize[i] bytes then I get the full pixel information about the frame ?
