TVHeadend build/install on Lubuntu 20.04-64bit with iGPU 8+ transcoding

Alin Gherghescu · 2022-12-03T02:38:34+00:00

This tutorial is intended for beginners interested in compiling tvheadend with HW GPU transcoding (using iGPU form Intel gen 8+). It is a little messy how I...

probably removing audio was not a good idea ... because WMC night not work without audio stream.
Try the second proposal: AAC with LC (instead of Main).
CQP and CBR should generate the same iGPU load ; unless WMC was not able to receive the stream CBR. Test with Kodi when you change the settings on VAAPI settings (sanity check), and test with WMC only after Kodi is working.

Sorry I don't know how to help you but I would like to try somehow before abandoning the project...
In the tvh configuration for wmc you must create an anonymous user (as in the image) otherwise wmc will not work displaying the message "no or weak signal", is it possible that when it has to do with this user?
Thanks

sorry ... that is not my area of expertise.

apollo

Ok, thanks for everything...

Hi,
is it possible to adjust video output to 25 fps?
Thanks

ukn_unknown

apollo we don't have this option natively. The only alternative is to use spawn with ffmpeg.

Please could you help me with ffmpeg?
Thanks

Let's clarify the constrain: client will have to use HTTP transport with spawn profile.
Install ffmpeg
sudo apt install ffmpeg
source info https://trac.ffmpeg.org/wiki/Hardware/VAAPI
Create the Stream Profile: Configuration / Stream / Stream Profile --> press +Add
Type: MPEG-TS spawn/builtin
Add a name in Profile name: <your choice>
Command line:
/usr/bin/ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i pipe:0 -vf 'fps=25,scale_vaapi=w=1920:h=-2:format=nv12' -c:v h264_vaapi -profile 578 -level 30 -bf 0 -b:v 3M -maxrate 6M -f mpegts pipe:1
Press +Create
Make this profile default or select this profile in your client.

apollo

Hi,
I tried the profile with kodi that displays a message "profile not available" however if I try to play a channel after a few seconds it starts the log shows some error...
Trying it also with mpc does the same thing, with wmc it doesn't work.
Thanks for your patience

ukn_unknown

apollo The message comes from the fact that HTSP profile is not available ... that is expected.
Can you copy those error lines in a text file and post it here? you can delete/override with *** any sensitive information from logs .. if you want.

Log attached
Thank you

apollo I think the ffmpeg for ubuntu 20.04 is too old.
ffmpeg version 4.2.7-0ubuntu0.1
based on this info I am afraid we need more radical changes ... like updating to 24.04 🙁 .
https://askubuntu.com/questions/1497843/how-to-install-latest-version-of-ffmpeg-on-ubuntu
FYI: we have a new fresh tutorial for 24.04 ... do you want to try it? https://docs.tvheadend.org/documentation/development/compiling/compiling-tvh-with-vaapi-support/for-lubuntu-24.04

Edit: actually even ffmpeg was not compiled with vaapi support in ubuntu 20.04:
configuration: --prefix=/usr --extra-version=0ubuntu0.1 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --enable-avresample --disable-filter=resample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-lv

Edit2:
I tested personally the line above on lubuntu 24.04 with ffmpeg installed with: sudo apt install ffmpeg --> works.

Hi,
I installed lubuntu 24 and configured the PC with the new tutorial, I still can't tell you if everything went well then I'll update you...
I have a problem with this version of lubuntu, I can't install rustdesk, when I open the downloaded file with package installer I get an error: cannot satisfy dependencies.
I have to install it because I have the mini pc under a 55" tv which is uncomfortable for working...
Could you help me? or do I have to write elsewhere?
Thanks

ukn_unknown

I never used rustdesk, but looking on their side ubuntu 24 is supported (lubuntu should be also). Maybe try to use the docker install? is complaining about any particular libraries (beside "cannot satisfy dependencies")?

apollo

Hi,
I couldn't install rustdesk, unfortunately I'm limited and I can't solve the problems that I encounter and so the easiest thing for me is to change the operating system version... I installed lubuntu 22 and also rustdesk, please tell me that with lubuntu 22 I can continue with the new tutorial...? Thanks

apollo

I figured it out myself, version 22 doesn't have ffmpeg + vaapi enabled...🙁
I'll try again with 24
Thanks

apollo

Done, I managed to install everything, now I scan the TV channels and try the profiles...
I have a problem with the monitor resolution, it does not save the settings, the PC is connected to a 55 4k TV, I set the resolution to 1280x720 and when I restart lubuntu the monitor returns to 4k, maybe I did something wrong?
I don't know whether to write on the new post...
Thanks

ukn_unknown

apollo there are two buttons (if I remember right): Apply and Save --> you have to press on both in order to save the resolution.

Hi,
I think I solved it by uninstalling and reinstalling rustdesk.

I configured the transcoding profiles as you showed me, h264+vaapi crashes after a few seconds while ffmpeg+vaapi runs fine, there are some errors in the log...

I read in a post about configuring wmc with tvh, hdhomerun and hdhrproxyiptv that during tvh transcoding the transport stream id ts and the service id that are essential for wmc are lost or changed, has anyone been able to make it work with this code ffmpeg -i - -f mpegts -mpegts_transport_stream_id 0x0006 -mpegts_service_id 0x0601 -metadata service_provider="SMR6" -metadata service_name="TF1" -c:a copy -c:v [codec video preferito] -hide_banner -loglevel panic pipe:1
Do you think it is possible to make it work with vaapi too...?
Thanks

ukn_unknown

apollo h264+vaapi crashes after a few seconds

Please confirm if the crash is in tvheadend or in other softwares.
Theoretically is possible ... but that will require some research (where we add those settings and how we transfer information from In stream to Out stream). Setting those with fixed values ... is't a horrible hack.

Hi stranger, since ffmpeg vaapi works please when you can and if you want could you consider the attached code to see if it can work? Thanks

ffmpeg -i - -f mpegts -mpegts_transport_stream_id 0x0006 -mpegts_service_id 0x0601 -metadata service_provider="SMR6" -metadata service_name="TF1" -c:a copy -c:v [codec video preferito] -hide_banner -loglevel panic pipe:1
