  • FFMPEG read audio convenience function

    7 mars 2016, par Phlox Midas

    In Matlab, there’s a function called audioread that takes a file name as input and returns a vector of samples and the sample rate like this :

    [samples, sampleRate] = audioread(fileName);

    I’ve been programming FFMPEG but finding it very low level. I have a file being read using a technique similiar to this. Is there any such equivalent C function in FFMPEG as there is in Matlab so I don’t have to fiddle with the low level stuff ? Or any library that can provide a nice API like this for FFMPEG (though I would just prefer this one function) ?

  • How to use hardware acceleration with ffmpeg

    5 avril 2018, par ixSci

    I need to have ffmpeg decode my video(e.g. h264) using hardware acceleration. I’m using the usual way of decoding frames : read packet -> decode frame. And I’d like to have ffmpeg speed up decoding. So I’ve built it with --enable-vaapi and --enable-hwaccel=h264. But I don’t really know what should I do next. I’ve tried to use avcodec_find_decoder_by_name("h264_vaapi") but it returns nullptr.
    Anyway, I might want to use others API and not just VA API. How one is supposed to speed up ffmpeg decoding ?

    P.S. I didn’t find any examples on Internet which uses ffmpeg with hwaccel.
