 execFFmpegBinary(cmd);

  • What is the difference between ffmpeg -thread and ffmpeg-mt ?

    7 novembre 2018, par S B

    Post ffmpeg-mt’s merge with ffmpeg...

    March 21, 2011

    Today FFmpeg-mt, the multithreaded decoding branch, has been merged into FFmpeg. This has been a long awaited merge, and we would like to thank Alexander Strange for his patience and hard work.

    ... what is to be expected of ffmpeg -thread usage ? Is this an under-the-hood transition or are ffmpeg users supposed to move their code to ffmpeg-mt to leverage multi-cores ?

  • Android-NDK building using the Bambuser source

    I am trying to use the FFmpeg source provided by the Bambuser.

    However, I am fail to build the files

    I get the following error :
