HELP needed - vaapi and tvheadend

Oli S.

Hi,

I do not know how to proceed - maybe somebody can help.

I have a Gemini Lake R J4125 with installed Intel i965 driver for Intel(R) Gemini Lake - 2.3.0.
Vainfo is showing proper installation. Details attached.

(Kernel 4.19.0-14-amd64, Linux Debian GNU/Linux 10 \n \l )

I have the latest version of tvheadend built and installed (v4.3-1947~gdbaa0f850, enabled static-ffmpeg)

Ordinary, non hw accelerated, codecs are working without problems.

vapi-codec for x264,x265,vp8,vp9 are offered in the stream/codec tab.

I can add the vapi codecs - but they stay disabled. I get no further debug-info!

Any hints?

Thx in advance, Oli

Another remark: pure ffmpeg (installed by apt) is supporting hw accel by vaapi correctly.

Plesa usepre button when post messages.

Is that packed are build by you or taken from some repo?
Post startup messages.

Oli S.

built by my own.
Thx in advance.

Saen Acro

Where is a startup messages of TVHeadend?

Oli S.

ahhhh, sory.
Startup mesasage: you mean a log of the start up? Any special debug settings therefore needed?

Oli S.

hopefully that's what you asked for:

attachec codec profle can be added. But it stay's disabled after adding.

Here is how I made it work. I have also Debian 10 installed on ASRock J4205. tvheadend: version 4.3-1923~gaaca05cc1
1. First absolutely check if in your system exists /dev/dri/renderD128. Then inspect its properties, in particular which group it belongs to, using a command:


$ ls -l /dev/dri/renderD128
crw-rw----+ 1 root render 226, 128 mar 28 14:19 /dev/dri/renderD128

All tutorials I read claims that is should belong to "video" group, but in my case it belongs to "render" group, so my user should also belong to "render" group. I wasted days to find that out. Check if your group was invalid. If so, then add your user to the same group of renderD128 (in my case group "render"), and try if your above solution works. If not:

Configuration/Stream/Stream Profiles/Add:
Type: MPEG-TS Spawn/build-in
In General Settings: as you wish.
In Spawn Settings/Command line:

ffmpeg -init_hw_device vaapi=foo:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device foo -i - -f mpegts -filter_hw_device foo -vf "scale_vaapi=w=-2:h=720,format=nv12|vaapi,hwupload" -c:v hevc_vaapi -b:v 1.5M -maxrate 2M -c:a libopus -b:a 32K pipe:1

Here's some description of that command:

-c:v hevc_vaapi

output format of video, in this case hevc. In my case it works, don't know if it will in yours. Others, like h264_vaapi, are listed in "Supported encoders" table on https://trac.ffmpeg.org/wiki/Hardware/VAAPI

h=720

720p vertical resolution.

-b:v 1.5M

average bandwidth of video, if I remember correctly.

-maxrate 2M

maximum bandwidth of video. If you cut this too short, video will be horrible.

-c:a libopus -b:a 64K

audio encoding with Opus and 64kbps. It can be also

-c:a copy

to just dump copy original audio without transcoding.

My ffmpeg is standalone ffmpeg from debian repository.

Here are couple of my profiles commandlines:
audio-only-opus:

ffmpeg -i - -f mpegts -vn -c:a libopus -b:a 28K -ac 1 pipe:1

hevc-vaapi-256p:

ffmpeg -init_hw_device vaapi=foo:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device foo -i - -f mpegts -filter_hw_device foo -vf "scale_vaapi=w=-2:h=256,format=nv12|vaapi,hwupload" -c:v hevc_vaapi -b:v 384K -maxrate 480K -c:a libopus -b:a 16K -ac 1 pipe:1

hevc-vaapi-320p:

ffmpeg -init_hw_device vaapi=foo:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device foo -i - -f mpegts -filter_hw_device foo -vf "scale_vaapi=w=-2:h=320,format=nv12|vaapi,hwupload" -c:v hevc_vaapi -b:v 384K -maxrate 512K -c:a libopus -b:a 16K -ac 1 pipe:1

hevc-vaapi-384p:

ffmpeg -init_hw_device vaapi=foo:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device foo -i - -f mpegts -filter_hw_device foo -vf "scale_vaapi=w=-2:h=384,format=nv12|vaapi,hwupload" -c:v hevc_vaapi -b:v 512K -maxrate 512K -c:a libopus -b:a 16K -ac 1 pipe:1

hevc-vaapi-480p:

ffmpeg -init_hw_device vaapi=foo:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device foo -i - -f mpegts -filter_hw_device foo -vf "scale_vaapi=w=-2:h=480,format=nv12|vaapi,hwupload" -c:v hevc_vaapi -b:v 512K -maxrate 512K -c:a libopus -b:a 16K -ac 1 pipe:1

hevc-vaapi-720p:

Hope this will help.

Oli S.

Dear Bart,

many thx for your detailed description. But I think you are describing how to use hwaccel by transcoding with external ffmpeg by spawning. This I already got to run, very similar to your solution.

But I want to enable the hwaccell with internal ffmpeg (via vaaoi codecs). This is still somehow disabled.

Best regards, O
