initialisation fail on ubuntu 18.04, on M3-8100Y model of the lattepanda alpha

[Changliu52]

Hi @bmegli
I can compile the package with no problem.
but when I ran ./realsense-nhve-h264 127.0.0.1 9766 infrared 640 480 30 5 /dev/dri/renderD128

The terminal outputs the error as below:

[AVHWDeviceContext @ 0x56125936bd20] Opened VA display via DRM device /dev/dri/renderD128.

The vainfo outputs the same error

Note, I'm using the new M3-8100Y model of the lattepanda alpha.
Please advice possible solutions

Hi @Changliu52,

Just curious, do you have both M3-7Y30 and M3-8100Y?

I confirm the problem on Amber Lake Y M3-8100Y on Ubuntu 18.04

I have M3-8100Y GPD Win2 as remote robot controller (but I used 19.04 MATE, which had support for GPD Win2 other hardware).

The situation on AmberLake Y with default OS configuration seems to be funny:

• VAAPI doesn't work in Ubuntu 18.04
• VAAPI works in 19.04, however I think I had problems with bitrate control
• VAAPI works in 20.04 (daily build 18.III.2020), however there are no entry points for HEVC and HEVC Main10 encoding

More details in HVE issue

I am looking into that.

This is doable:

• hardware supports it
• correct software stack supports hardware

There are some hacky workarounds for CoffeLake, like here, this example is too hacky to use but shows that problem and workaround should exist.

Edit:

• crossed out link (tested with live USB, doesn't do anything)
• turns out I was using 19.04, not 19.10

Just curious, do you have both M3-7Y30 and M3-8100Y?

Yes, Just got the M3-8100Y delivered last weekend, so was trying out different setups on the new one, while leaving the old one for some of my old stuffs.

Since it is quite empty now, so I can try different OS and setup.
So for the time being, I think I will get the reinstallation on the M3-7Y30 with 18.04, and test out different configurations on M3-8100Y following bmegli/hardware-video-encoder#21.

Thank you so much for the clarification!

[bmegli]

Good news.

20.04 has both drivers (iHD and i965). M3-8100Y works with both drivers.

Initial testing with HVE shows that it is enough to force i965 with environment variable and everything seems to work.

Like this:

LIBVA_DRIVER_NAME=i965 ./hve-encode-raw-hevc10 10 /dev/dri/renderD128

See more details in HVE if you are interested.

Looks like 20.04 is the future. Go figure!

[Changliu52]

That's fantastic! Great work @bmegli !
Would you think the bitrate control can work well also?

[bmegli]

Would you think the bitrate control can work well also?

It works.

You run it like this:

LIBVA_DRIVER_NAME=i965 ./realsense-nhve-hevc 192.168.0.100 9768 depth 848 480 30 500 /dev/dri/renderD128 8000000 0.000015625

Hi @bmegli
I was testing the on the 20.04 on M3-8100Y.
I have set LIBVA_DRIVER_NAME=i965

the encoder seems to still have problem to initialise. The console output is:

@Changliu52

We now have working m3-8100Y in 18.04, tested with ffmpeg_image_transport.
