2022-05-18py: cam_kms: Fix multistream displayTomi Valkeinen
Instead of doing an atomic commit for each stream, do a single commit for the two planes. This fixes the issue that only the first plane was actually shown.

2022-05-10py: Add cam.pyTomi Valkeinen
Add cam.py, which mimics the 'cam' tool. Four rendering backends are added: * null - Do nothing * kms - Use KMS with dmabufs * qt - SW render on a Qt window * qtgl - OpenGL render on a Qt window All the renderers handle only a few pixel formats, and especially the GL renderer is just a prototype.
