  • libswscale/aarch64 : add another hscale specialization

    13 août 2022, par Swinney, Jonathan
    libswscale/aarch64 : add another hscale specialization

    This specialization handles the case where filtersize is 4 mod 8, e.g.
    
12, 20, etc. Aarch64 was previously using the c function for this case.
    
This implementation speeds up that case significantly.

  • Merging input Streams with nodejs/ffmpeg

    14 septembre 2020, par jAndy

    I'm creating a very basic and rudimentary Video-Web-Chat. On the client side, I'm going to use a simple getUserMedia API call to capture the webcam data and send video-data as data-blob to my server.

    &#xA;

    From There, I'm planning to either use the fluent-ffmpeg library or just spawn ffmpeg myself and pipe that raw data to ffmpeg, which in turn, does some magic and pushes that out as HLS stream to an Amazon AWS Service (for instance), which then gets actually displayed on a Web Browser for all participating people in the video chat.

    &#xA;

    So far, I think all of this should be fairly easy to implement, but I keep my head spinning around the question, how I can create a "combined" or "merged" frame and stream, so the output HLS data from my server to the distributing cloud service has only to be one combined data stream to receive.

    &#xA;

    If there are 3 people in that video chat, my server receives 3 data streams from those clients and combines these data streams (from the individual web-cam data sources) into one output stream.

    &#xA;

    How could that be accomplished ?&#xA;Can I "create" a new frame with ffmpeg, so to speak ? I would be very thankful if anybody could give me a heads up here, maybe I'm thinking in a complete wrong direction.

    &#xA;

    Another question which arises to me is, if I really can just "dump" any data, which I'm receiving from a binary blob created from getUserMedia or MultiStreamRecorder to ffmpeg or if I have to specify somewhere and somehow the exact codecs being used etc.?

  • swscale/aarch64 : add vscale specializations

    swscale/aarch64 : add vscale specializations

    This commit adds new code paths for vscale when filterSize is 2, 4, or
    
8. By using specialized code with unrolling to match the filterSize we
    
can improve performance.
