Description

Convert stereoscopic video between different representations using fragment shaders.

The element can use either property settings or caps negotiation to choose the input and output formats to process.

Examples

1
gst-launch-1.0 videotestsrc ! glupload ! glviewconvert ! glimagesink

Simple placebo example demonstrating identity passthrough of mono video

1
2
gst-launch-1.0 videotestsrc pattern=checkers-1 ! glupload ! \
    glviewconvert input-mode-override=side-by-side ! glimagesink -v

Force re-interpretation of the input checkers pattern as a side-by-side stereoscopic image and display in glimagesink. FBO (Frame Buffer Object) and GLSL (OpenGL Shading Language) are required.
