  • How to change the size of audio visualisers in ffmpeg ?

    3 juillet 2017, par Meme Stream

    I have this command in ffmpeg :

    echo shell_exec("$ffmpeg  -i test.aiff -y -filter_complex '[0:a]showfreqs=s=1920x1080:mode=bar:ascale=log:fscale=lin:win_size=w1024:win_func=poisson:colors=blue,format=yuv420p[v]' -map '[v]' -map 0:a output2.mp4 2>&1");

    I want to make it so that the video dimensions are still 1080p but the showfreqs graph is squashed and located near the bottom of the screen. How do I do this ? Thanks.

  • AVFrame data format

    10 mars 2021, par Валентин Никин

    I process the raw data from AVFrame.data. Pixel format of this frames is AV_PIX_FMT_YUV420P. I want to understand in what range of values is this data located.

    &#xA;

    Seems UV (in YUV scheme) must be in [-128, 128] range, CbCr (in YCbCr) must be in [0, 255]. What scheme used in FFmpeg ?
