Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav
Hello, brethren :-)
As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".
| import av | |
| from av.video.frame import VideoFrame | |
| from av.video.stream import VideoStream | |
| # В этом списке будем хранить кадры в виде numpy-векторов. | |
| array_list = [] | |
| # Откроем контейнер на чтение | |
| input_container = av.open('input.mp4') |
This is a writeup about how to install Ubuntu 16.04.1 Xenial Xerus for the 32-bit hard-float ARMv7 (armhf) architecture on a Qemu VM via Ubuntu netboot.
The setup will create a Ubuntu VM with LPAE extensions (generic-lpae) enabled. However, this writeup should also work for non-LPAE (generic) kernels.
The performance of the resulting VM is quite good, and it allows VMs with >1G ram (compared to 256M on versatilepb and 1G on versatile-a9/versatile-a15). It also supports virtio disks whereas versatile-a9/versatile-a15 only support SD cards via the -sd argument.
This gist will help you to compile ffmpeg with NVENC, QSV, VAAPI, VDPAU, and OpenCL support.
nVidia
nvresizepatch is outdated and not more compatible to the latest version of FFmpeg, so it's not included in this documentation.
(even if I've passed a lot of time at trying to make it compile... without any success)
Please don't rely on this page: https://developer.nvidia.com/ffmpeg, the implementation is a hack and was never been added to the main FFmpeg tree.
