  • Encoding and processing into web-friendly formats

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).

  • How to use ffmpeg for streaming mp4 via websocket

    18 mai 2021, par curtiss

    I've written a sample in nodejs which streams some input to the client via websocket connection in mp4 format. On the client side, the mp4 packages are added to a MediaSourceBuffer.

    


    This runs fine, but only if the client gets the stream from the beginning with the first package. So another client can't play the current Stream, because he won't get the Stream from the beginning.

    


    I tried (try&error) to save the first package ffmpeg sends and send this at the beginning of a new connection, then the current stream. Then the MediaSourceBuffer breaks because of encoding error..

    


    Here is the ffmpeg command :

    


    -i someInput -g 59 
-vcodec libx264 -profile:v baseline 
-f mp4 -movflags empty_moov+omit_tfhd_offset+frag_keyframe+default_base_moof
-reset_timestamps 1
-


    


    The part "empty_moov+omit_tfhd_offset+frag_keyframe+default_base_moof" should make the Streampackages independent in putting the moovatom at the beginning of each part and sizing the parts in 59 frames each by keyframe, so I don't get it why I can't view the Stream beginning after the start.

  • FFMPEG Online Redistribution in IIS Server Streaming Onvif IP Camera

    23 avril 2015, par Benny Chen

    I’m very new with ffmpeg. Consider the following case :

    I have several onvif ip camera connected to the network with an IIS server inside it. I’d like to allow client to streaming to any of ip camera inside the network but it must through the IIS server.

    So basically each of ip camera will stream to IIS server in single stream and IIS server will re-distribute to many client who request it. My question is how to setup iis server to works with this scenario ? And an example of ffmpeg command line to read from rtsp ip camera and send it the iis server which will re-distribute it to client.
