Initialisation fail in ubuntu 16.04

Dear @bmegli

I was able to compile the code with no problem in ubuntu 16.04 following https://github.com/bmegli/network-hardware-video-encoder/issues/3

But when running with ./realsense-nhve-h264 127.0.0.1 9766 color 640 480 30 50 /dev/dri/renderD128 on LattePanda Alpha, it reports the following error

hve: failed to create a VAAPI device
nhve: failed to initalize hardware encoder
unable to initalize, try to specify device e.g:

./realsense-nhve-h264 127.0.0.1 9766 color 640 360 30 5 /dev/dri/renderD128
./realsense-nhve-h264 127.0.0.1 9766 infrared 640 360 30 5 /dev/dri/renderD128

I have checked that I can ls /dev/dri/renderD128. Not sure If there is any setup I need to go through? Im runing with realsense d435

Thank you in advance.

Hi @Changliu52,

Since we have one working system and the second to diagnose this should be just a matter of time.

A couple of ideas:

What version of Ubuntu 16.04 do you have installed? Desktop, sever, minimal, headless? The default desktop should have all the dependencies installed by default (hardware encoding worked on live cd after resolving library issues but the test wasn't on LattePanda Alpha)
Could you paste the output of:
```
vainfo
```
and

vainfo --display drm --device /dev/dri/renderD128

If you don't have vainfo install it with:

sudo apt-get install vainfo

Could you paste the output of
```
ffmpeg -encoders | grep vaapi
```
Could you paste the ouput of:

ldd realsense-nhve-h264

This will tell us what libraries we are using at runtime. There are obvious like avcodec,avutil but also indirect like libva, libva-drm ant lots of other coming from ffmpeg and librealsense depending how they were compiled.

We are mostly interested in the cases when some library is not used from the default system path (/lib, /usr/lib).

If all else fails this should be working by default on 18.04 desktop with LattePanda Alpha. There may still be minor difference, I have 7th gen M3-7Y30, you may have the newer 8th gen M3-8100Y).

Edits:

Added info about installing vainfo if missing

Just checked with:

LattePanda Alpha (m3-7Y30)
Ubuntu 16.04.6 live USB
network-hardware-video-encoder#3 ffmpeg install way

and got working hardware encoding with NHVE out of the box so we need output from above commands to diagnose further.

Also information which version of LattePanda Alpha you have may be helpful.

Looks like it is still using ffmpeg 3.4.1 I compiled from source?

My LattePanda is also M3-7Y30 I removed the ffmpeg 3.4.1 from the installation and recompiled the RNHVE package. Its better but gives the following output:

VAAPI

VAAPI configuration in the OS is ok

Compiled ffmpeg

It seems it was compiled without vaapi support and with minimal option set (only --enable-shared)

The output of

ffmpeg -encoders | grep vaapi

Should be:

 V..... h264_vaapi           H.264/AVC (VAAPI) (codec h264)
 V..... hevc_vaapi           H.265/HEVC (VAAPI) (codec hevc)
 V..... mjpeg_vaapi          MJPEG (VAAPI) (codec mjpeg)
 V..... mpeg2_vaapi          MPEG-2 (VAAPI) (codec mpeg2video)
 V..... vp8_vaapi            VP8 (VAAPI) (codec vp8)

At least passing --enable-vaapi to configure, maybe also some other switches would be necessary and compiled version maybe would work.

The current state

I am not sure.

I would do:

cleanup the compiled version
sudo ldconfig

cleanup rnhve and make sure it is cloned with --recursive option


git clone --recursive https://github.com/bmegli/realsense-network-hardware-video-encoder.git

cd realsense-network-hardware-video-encoder mkdir build cd build cmake .. make


Then I would try with infrared (infrared uses native VAAPI pixel format - nv12):

```bash
./realsense-nhve-h264 127.0.0.1 9766 infrared 640 360 30 5 /dev/dri/renderD128

Also in the build directory:

we don't have to diagnose the full RNHVE, or even NHVE library
you could diagnose HVE instead:

# in RNHVE build directory after make
cd network-hardware-video-encoder
cd harware-video-encoder
./hve-encode-raw-h264 10 /dev/dri/renderD128

I am not yet sure what's going on.

[h264_vaapi @ 0x1b35940] Input surface format is yuyv422.
[h264_vaapi @ 0x1b35940] No usable encoding profile found.

4.2 is enough far away from 3.4 (2 years of development) that something may have changed.

One thing I am certain:

I have checked with live USB and NHVE, the default test program uses NV12 pixel format, it worked
so try with infrared which maps to NV12

Later on, ~~KabyLake VAAPI hardware encoding only supports 4:2:0 chroma subsampling~~ so maybe it is complaining in the newer version that it will not be able to use the 4:2:2 information from chroma yuyv422.

In FFmpeg this would correpond to FF_PROFILE_H264_HIGH_422 ~~(not supported by VAAPI).~~

Somewhat blindly I have explicitly set the profile FF_PROFILE_H264_HIGH in the branch explicit-h264-profile which may fix the problem.

So you may try:

#in RNHVE directory
git pull
git checkout explicit-h264-profile
cd build
make
./realsense-nhve-h264 127.0.0.1 9766 color 640 360 30 5 /dev/dri/renderD128

Later on I will check this myself (no time now)

Edit:

strike through false claims - VAAPI supports 4:2:2 chroma subsampling, just not in the ancient version

I checked myself in 16.04.6 with ffmpeg 4.2, and infrared streaming is working, color and depth not. Looks like HVE needs some update for 4.2.

So you may try [...]

Checked it, didn't help.

I am not planning to update HVE for FFmpeg 4.2 now, it is meant for 18.04 LTE (10 year support) with FFmpeg 3.4.

Your options are:

~installing FFmpeg 3.4 from ppa (for example this if you are on 16.04.2, on 16.04.6 you will meet some dependency problems)~
~installing FFmpeg 3.4 from source~
switching to 18.04 which the library is tested on
~solving the problem yourself (updating RNHVE/NHVE/HVE for FFmpeg 4.2)~
finding some other way

For option 1 and 2 you should probably first remove 4.2 ffmpeg, avcodec-dev, avutil-dev

sudo apt-get remove ffmpeg libavcodec-dev libavutil-dev

Then remove ppa (search for the correct command or remove from the ppa list)

Edit:

striked through options that will not lead to working depth encoding (see post below)

both master and explicit-h264-profile worked with infrared streaming. ./realsense-nhve-h264 127.0.0.1 9766 infrared 640 480 30 5 /dev/dri/renderD128

but non works with color ./realsense-nhve-h264 127.0.0.1 9766 color 640 480 30 5 /dev/dri/renderD128 with the same error as before

Looking at the output of vainfo, the problem is deeper than just FFmpeg version.

the versions of VA-API differ (1.1.0 in 18.04 vs 0.39.0 in 16.04)
vaDriverInit functions differ
libva versions differ (2.1.0 vs 1.7.0)
Intel i965 driver versions may differ

The most important part:

VAProfileVP8Version0_3          :   VAEntrypointEncSlice
      VAProfileHEVCMain               : VAEntrypointVLD
      VAProfileHEVCMain               : VAEntrypointEncSlice
      VAProfileHEVCMain10             : VAEntrypointVLD
      VAProfileVP9Profile0            : VAEntrypointVLD
      VAProfileVP9Profile2            : VAEntrypointVLD

In 16.04 you are missing the profile for HEVCMain10 encoding.

This is what you should have (18.04 ecosytem):

     VAProfileHEVCMain               :  VAEntrypointVLD
      VAProfileHEVCMain               : VAEntrypointEncSlice
      VAProfileHEVCMain10             : VAEntrypointVLD
      VAProfileHEVCMain10             : VAEntrypointEncSlice

VAProfileHEVCMain10 : VAEntrypointEncSlice

So even if you solve the problem with FFmpeg version you will not be able tu run depth encoding.

To get it working you would probably have to:

replace i965 drivier with newer version
replace libva with compatible version
recompile ffmpeg
other dependencies and problems may emerge on the way

With 16.04 reaching end of support next year, 20.04 LTS coming next month, this is not worth the effort.

I suggest switching to 18.04 LTS.

I see. Thank you very much for the suggestions. It has been super useful!

For reference:

intel-vaapi-driver:

Version 1.7.3 - 10.Nov.2016

Add support for HEVC 10bit encoding on KBL

On 16.04 you have 1.7.0 version, on 18.04 there is 2.1.0 version
