In mixed presentation mode, both live A/V and non-live A/V data is blended/mixed together and presented using the live A/V timing. The internal audio mixer provides audio mixing only (audio sample rate and other attributes of the two sources must be identical). The internal video/graphics alpha blender is used to blend the two video streams. In the mixed presentation mode, the following stream requirements must be fulfilled.

The resolution of the video/graphics frames going to the mixer must be the same.

The input streams to the audio mixer requires the audio sampling frequency to be the same between two streams.
