  • imc : Use correct position for flcoeffs2 calculation

    10 juillet 2015, par Andreas Cadhalpun
    imc : Use correct position for flcoeffs2 calculation

    flcoeffs2[pos] should be the log2 of flcoeffs1[pos].
    
flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf,
    
causing problems further down.
    

    This seems to have been copied from imc_decode_level_coefficients in
    
commit 4eb4bb3 without updating the position.

  • FFMPEG Extract subtitles at webvtt format while keep position on the screen

    30 septembre 2020, par Maxou

    i'm working on a project where I need to extract subtitles from video files and convert it to WEBVTT format. But when I extract and convert it with FFMPEG my webvtt files doesn't keep the position.

    &#xA;

    What I want

    &#xA;

    00:00:11.000 --> 00:00:13.000 align:start&#xA;

    &#xA;

    What I get

    &#xA;

    00:00:11.000 --> 00:00:13.000&#xA;

    &#xA;

    While when I test to extract at .ass files the position of the subtitles is keep.

    &#xA;

    To extract I use this command

    &#xA;

    ffmpeg -i {filename} -map 0:s:0 -muxdelay 0 -f webvtt subtitles.vtt&#xA;

    &#xA;

    Thanks in advance
