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.
