timing_info_present_flag Support

[DoM1niC]

relates to bluenviron/mediamtx#3902

I asked ChatGPT for a fix 💯 Can this help you?

I don't have any Golang Skills and hope to find a fix to use the AMD HW AV1 Encoder with Mediamtx 👍🏻

if h.TimingInfoPresentFlag {
    // Beispiel: Verarbeiten der Timing-Informationen
    numUnitsInTick, err := bits.ReadBits(buf, &pos, 32)
    if err != nil {
        return err
    }

    timeScale, err := bits.ReadBits(buf, &pos, 32)
    if err != nil {
        return err
    }

    if numUnitsInTick == 0 || timeScale == 0 {
        return fmt.Errorf("invalid timing info: num_units_in_tick or time_scale is zero")
    }

    // Berechnen der Bildrate
    h.FrameRate = float64(timeScale) / float64(numUnitsInTick)
}

Sorry for the question, but do you think we're stupid?
