| This script has the advantage of making audio from the HDMI stream available to voctomix, so that audio and video are in sync. This is particularly useful when the lecturer plays a video with a lot of spoken text. This audio source can then be selected in voctomix. | This script has the advantage of making audio from the HDMI stream available to voctomix, so that audio and video are in sync.

| + | ## Bild Rot/ | ||
| + | |||
| + | Wir haben öfters das Problem beobachtet, dass die Bildausgabe des Tronsmart am HDMI-In einer Decklink MiniRecorder komplett Dunkelrot, Dunkelgrün oder komplett Schwarz ist, obwohl der Tronsmart nachweißlich auf die korrekte Auflösung eingestellt ist und am Beamer oder Fernseher korrekt funktioniert. Das Problem kann durch zwischenschalten des HDMI-to-SDI-Wandlers und grabben der Slides vom SDI-In der MiniRecorder behoben werden. | ||
| + | |||
| + | Tests zeigten, dass manchmal das Tauschen des HDMI-Kabels hilft, manchmal aber auch nicht. Auch das Tauschen des Tronsmarts hilft nicht immer. Diese Beobachtungen legen nahe, dass das Problem nicht alleine am Kabel noch am Tronsmart und vmtl. auch nicht an der Karte liegt. Warscheinlicher ist eine Kombination der Faktoren mit Umgebungs-RF, | ||
