  • 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 merge the raw pcm data of two channels ?

    15 mai 2019, par maximedupre

    I have two Float32Arrays containing the raw pcm data of the left and right channel. Is it possible to create a Float32Array that combines both channel ? If so, how would I do that ? Can I simply concatenate the arrays ?

    Cheers !

  • How OpenGL directly manipulates data on GPU that a video hardware decoded by FFmpeg CUDA

    24 janvier 2019, par gn cavalry

    Ubuntu 18.04
    FFmpeg 4.1
    CUDA 10.0

    What I want to do is using FFmpeg CUDA decode a video, directly peocess data on GPU by GLSL , then encode data using FFmpeg CUDA. Like this :

    Raw Video —> FFmpeg CUDA decoder —> GLSL —> FFmpeg CUDA encoder —> New Video

    Here is the short code :

    ret = avcodec_send_packet(decoder_ctx, pkt);
    
while (ret >= 0) {
    
    ret = avcodec_receive_frame(decoder_ctx, frame);
    

    
    /**
    
     * Now CUDA decoded data is stored on GPU and referenced by frame
    
     * How can GLSL manipulate decoded data on GPU directly, 
    
     * without transfer it to CPU and load to GPU again by glTexImage2D()
    
     */
    

    

    
    // I don't if the following code is right, if GLSL processed data is still referenced by frame
    
    while (avcodec_send_frame(encoder_ctx, frame)) {
    
        avcodec_receive_packet(encoder_ctx, &enc_pkt);
    
    }
    
}

    Can anyone help me ? Thanks very much !

  • Injecting KLV data in video stream using ffmpeg

    29 octobre 2022, par lsilk

    Does anyone here have any experience with streaming video on one stream, for example 0:0, and then taking a .bin file in klv format and putting it in 0:1, and then outputting that to a mpegts udp stream ? I have it working, the only problem is that I have written a python program to update the klv data file while it is streaming, but it doesn't seem to be updated in the stream.

    


    My command : ffmpeg -I "filepath.mpg" -f data -i "filepath.bin" -filter:v fps=60 -map 0:v:0 -map 1:d:0 -f mpegts udp ://IP:PORT

    


    Ive tried -I from a local file, I've also tried streaming the .bin file from an other stream after updating it, but then the fps drops to about 0.5.
