The situation is quite complex.

Support depends on:

  • hardware (generation like KabyLake, AmberLake Y, CoffeLake)
  • used driver (version and type, there are at least two: i965_drv_video.so, and iHD_drv_video.so)
  • libva
  • ffmpeg

KabyLake (7th gen)

The library is tested with KabyLake on 18.04, everything works here.

AmberLake Y (8th gen)

Here the situation is funny.
VAAPI:

  • doesn't seem to work in 18.04 in OS
  • works in 19.04
  • works in 20.04 but without profiles for HEVC and HEVC Main10 encoding with both iHD and i965 drivers, with iHD HEVC and HEVC Main10 encoding is not supported may also depend on driver build (full featured vs free kernel)

Also from what I remember in 18.04 and 19.04 it uses i965 and in 20.04 iHD dirver by default.

18.04

By default VAAPI doesn't work in the OS.
Through 965_drv_video.so.

Needs more investigation.

19.04

I used it on m3-8100Y with GPD Win2, worked out of the box with:
Ubuntu MATE 19.04 for GPD Pocket 2 & GPD WIN 2

H264 and HEVC Main10 worked however I had doubts whether bitrate control worked correctly. Didn't seem so.

20.04 (daily build 18.03.20)

VAAPI works through iHD_drv_video.so however there are no entry points for encoding HEVC and HEVC Main10 (only decoding).

Edit:

  • 20.04 has both drivers.
  • everything seems to work when selecting i965 driver manually
  • see posts below for the details
  • it is possible that HEVC would work with Full Feature iHD build (I haven't tried with AmberfLake-Y yet)

Edit:

  • CoffeLake -> AmberLake Y (correct for m3-8100Y)
  • it seems I am using 19.04, not 19.10
  • i965 is used by default in 19.04 (not iHD), just with different version than in 18.04
  • added information about both drivers working in 20.04

20.04 and m3-8100Y

Actually 20.04 has both drivers iHD and i965.

It is possible to force i965, and everything seems to work with m3-8100Y through i965
(needs more testing to be certain)

Also HEVC Main10 encoding through HVE works this way (by setting environment variable)

In general, for Intel there are two drivers:

Driver Generation Repository
i965 driver gen5 to gen9.5 ​https://github.com/intel/intel-vaapi-driver
iHD driver gen8+ ​https://github.com/intel/media-driver

For i965 support for version/generation may be found in intel-vaapi-driver NEWS

For iHD see this table noting that:

  • there are two driver builds
    • Full Feature Build (closed source)
    • Free Kernel Build (fully open source with limited functionality)
  • with Free Kernel Build encoding support generally comes later (generation wise)

Some devices (between gen8 and gen9.5) are supported by both drivers which means at least 3 possibilities (i965 and two builds of iHD), not counting other factors like GuC/HuC and low power encoding.

20.04 and Icelake

Tested with i5-1035G7.
Seems to work only with iHD driver.

HEVC Main10 encoding required Full Feature Build to work.

sudo apt install intel-media-va-driver-non-free

Maybe it would also work by loading GuC/HuC.

HEVC Main10 decoding:

  • works from 20.04 -> 20.04, 20.04 -> 18.04
  • doesn't work 18.04 -> 20.04 (see HVS#10)

Update:

  • updated HEVC Main10 decoding info
