## glstereomix glstereomix |

## Types and Values

struct | GstGLStereoMix

## Description

Combine 2 input streams to produce a stereoscopic output stream. Input views are taken from the left pad and right pad respectively, and mixed according to their timelines.

If either input stream is stereoscopic, the approproriate view (left or right) is taken from each stream and placed into the output.

The multiview representation on the output is chosen according to the downstream caps.
