  • ffmpeg setting up in wamp (in local) OR server

    5 janvier 2013, par Rahul TS

    can anyone explain the procedure of installing ffmpeg in wamp.
    I got an answer to my previous question on ffmpeg and wamp that we have to interface the ffmpeg (here) with wamp.

    I need to have a step by step process of how to do this, as I am confused with the interfacing little bit

    I also want to know what is a way to install this ffmpeg into the server, or the procedure to do before we do the encloding procedures

  • For converting video to frames, should I do client or server side processing ?

    23 mars 2024, par Tomas Marson

    Here is the thing, I have a Nodejs API that serves one video at a time when client request it.

    


    The client (made in react) receives the video, which has no more than 15 seconds, watch it and decide if he wants to approve or deny it.
If he approves the video, it must be displayed in a sort of frames carousel, with one frame per second, so there is no more than 15 images/frames.

    


    So the question is, should I do the conversion video-to-frames on client once he approves the video or should I do it on server-side and then request each frame (or streaming all frames with one request if possible) ?

    


    Now, I'm doing the conversion on server with ffmpeg, but it seems tricky to send all the frames when the client already have them inside the video.

    


  • How to decouple between ffmpeg and rtp server ?

    2 février 2023, par dror

    I have a ffmpeg-based worker that handles video-generation jobs at very high throughput.
Long videos need to be streamed while being generated.

    


    For that purpose, I have introduced a WebRTC server named Janus-Gateway with its streaming plugin, and set the application's output to an rtp:// endpoint at that server (ffmpeg can stream a single stream using the ​RTP protocol).

    


    In order to avoid buffering problems on the other hand, the streaming is done through the ffmpeg's -re option, which means that the stream will be streamed in real-time, i.e. it slows it down to simulate live streaming.

    


    [ffmpeg-based app] (#1)--> [rtp://janus:port @ webrtc server] (#2)--> [webrtc subscribers]


    


    How can I continue processing video jobs at high throughput while streaming the results at real-time speed ? I need somehow to decouple ffmpeg output (stage #1) so that consumers at stage #2 get streams at natural playback speed.
