  • 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" (...)

  • How to stream only a part of a video without downloading the whole thing ?

    11 mai 2024, par Abbas

    I am building a YouTube video trimmer, and currently, it takes the YouTube video ID, downloads the whole video from the server (Even it is like 10 hours long), and then it trims it according to user's inputted timeframe using ffmpeg.

    


    Now the problem with this is that it takes so much time to download the whole video even if we want a small piece of it hence it is highly impractical.

    


    I was thinking to implement something like an HTML5 video player does when you seek the video forward. It just jumps to the part where you seek-ed to without downloading the part you skipped over. How can I only download a part of a video file from a server in form of a buffer and then generate an already trimmed video file from that ? I don't know if that is even possible on the server-side, but video players do it on the client-side.

    


  • How can I separate audio channels using libav C API ?

    20 mai 2019, par zhenghong li

    I have some stereo audio files, and I wanna separate the left channel from the right channel and output the two channels into two different files/streams/containers using libav C API, how can I do that ? The libav API documentation is good, but it takes time to read and try all these functions. Could anyone please give me a specific example.

  • FFmpeg VP9 - Different Quantisation Parameters but same output files

    29 juin 2017, par C. Kmer

    I want to encode a video with vp9 with different quantisation parameters (qp=[16,20,24,28,32]). Unfortunately the output files have the same data rate after encoding and don’t show any quality differences.

    This is my code for qp=20 :

    ffmpeg -s:v 3840x1920 -framerate 30 -i video_3840x1920_30fps_8bit_420_erp.yuv -c:v libvpx-vp9 -qp 20 -f avi out.avi

    Many thanks for any pointers you can give me.
