  • 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" (...)

  • What's the most performant way to encode an mp4 video of frames from a webgl canvas using Javascript in a web browser ?

    17 janvier 2024, par Keith Carter

    I can capture the frames from the canvas using readPixels (https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/readPixels) but then what ?

    


    I think there are a few wasm versions of ffmpeg but they're slow.

    


    I found this web assembly mp4 encoder but it's no longer supported and doesn't work in Chrome on my phone (Android 13).

    


    Any other suggestions ?

    


  • Looking for Javacpp FFMPEG CustomIO Example

    26 février 2017, par user1902291

    I am trying to get Custom IO working with JavaCPP FFMPEG. Has anyone succeeded at this ? Can you post your code ?

    Here is mine (Scala), which does not work. It compiles and runs, but does not seem to call my Read and Seek methods

    val readPtr = new Pointer()
    
val seekPtr = new Pointer()
    
val userDataPtr = new Pointer()
    
val read = new Read_packet_Pointer_BytePointer_int(readPtr) {
    
  override def call(userDataPtr: Pointer, @Cast(Array("uint8_t*")) buf: BytePointer, buf_size: Int): Int = {
    
    super.call(userDataPtr, buf, buf_size)
    
  }
    
}
    
val seek = new Seek_Pointer_long_int(seekPtr) {
    
  @Cast(Array("int64_t")) override def call(userDataPtr: Pointer, @Cast(Array("int64_t")) offset: Long, whence: Int): Long = {
    
    super.call(userDataPtr, offset, whence)
    
  }
    
}
    

    
val bufferSize = 1024 * 1024
    
val readBuffer = new BytePointer(bufferSize)
    

    
val avioContext = avformat.avio_alloc_context(
    
  readBuffer,   // internal buffer
    
  bufferSize,   // and its size
    
  0,            // write flag (1=true,0=false)
    
  userDataPtr,  // user data, will be passed to our callback functions
    
  read,
    
  null,         // no writing
    
  seek
    
)
    

    
formatContext.pb(avioContext)
    
formatContext.flags(formatContext.flags | avformat.AVFormatContext.AVFMT_FLAG_CUSTOM_IO)
    
formatContext.iformat(avformat.av_find_input_format("mp4"))
    

    
avformat.avformat_open_input(formatContext, null.asInstanceOf[String], null, null)

  • tcp : Explicitly convert a pointer to a boolean integer

    9 septembre 2013, par Martin Storsjö
    tcp : Explicitly convert a pointer to a boolean integer

    This fixes warnings about making integers from pointers without
    
a cast, and avoids the theoretical case where the lower 32 bits of
    
the pointer would all be zero where the implicit cast wouldn’t give
    
the right result.
