One Line Summary

How the kernel can help user space make best use of hardware for multimedia acceleration.

Abstract

HW-accelerated multimedia is possible nowadays, but is restricted to using one specific subsytem or combination of subsystems. Users shouldn’t have to care about those restrictions, and parts are missing kernel-side to solve that.

Today’s multimedia usage mixes V4L2, libVA, VDPAU, OpenGL, GEM/TTM, OpenMAX, OpenCL, 3rd party API/drivers, gpu, dsp, dedicated boards and cpu.

This talk will give a userspace point of view on what bottlenecks/blockers are encountered when using/mixing those various (sub)systems and what’s missing to make Linux the killer platform out there for as many multimedia usages as possible.

The point of this talk is not to force adoption of a certain subsystem, but to bring to the table an extensive point of view of the problems we have to fix.
