Description
Split from #370, see also #202 for the decoding side.
The only hardware supported by libva for accelerated encoding are some Intel chips.
Pointers:
- libva
- qemu patch (good starting point / example)
Note: libva can encode to other formats (avc, mpeg2, ..) and maybe this can be useful in the future.

As per Fedora 28 Planning For VA-API 1.0 Support, Libva 2.0 was released last October with H.264 FEI support in its API, deprecating older parts of the API, fixing a race condition with the Wayland support, renaming some parts of the API, improving the logging capabilities, and various other changes. Libva 2.0 broke API/ABI compatibility with older versions of this Intel-developed Video Acceleration API.
We want to target libva 2.0, so let's wait for Fedora 28 beta.

Raising, Intel's Valley Vista makes this much more interesting. Awaiting hardware to take this on.
