    avcodec/srtdec: attempt to correct SubRip positioning · 5c219e28
    Clément Bœsch authored
    The positioning was completely wrong. First, the coordinates are
    expressed in ASS playback resolution (which is by default 384x288).
    Secondly, the coordinates define a drawing rectangle, not a moving area.
    The previous code was making subtitles move from a random position to
    another random position.
    
    Here we rescale assuming the video resolution is a DVD one (720x480). We
    can't really do anything better so far, but since this positioning
    information is often from a DVD rip we can consider them relatively
    safe.
