Anyways, I don't actually think my Chromebook, the Exynos 5420 Samsung Chromebook will last very long. The T600 series of GPUs are poorly supported in Panfrost, the video driver works through. But it's old and unstable, freezing up every now and then. Anyways, see below for the benchmark results.

Source video : Megumi Nakajima @ H264 1080p30
Recording (CPU) Tests :
Two CPU streams (mpv and ffmpeg) - Stream 1 = 144 seconds for ~6780 frames (47.1 FPS) ; Stream 2 = 53 FPS

One VPU (v4l2m2m-copy) and One CPU stream - Stream 1 = 155 seconds for ~6780 frames (43.7 FPS) ; Stream 2 = 63 FPS

One VPU Stream alone = 137 seconds for ~6780 frames (49.5 FPS)

One CPU Stream alone = 69 FPS

Off screen (No recording == no CPU overhead)
One CPU Stream alone = 93 FPS
One VPU Stream alone = 52.2 FPS
