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...

I think the problem is in tvh, to create the h264+vaapi profile I followed all the steps you described above, I tried with kodi and after a few seconds the streaming stops, I attached the log.

With the ffmpeg+vaapi profile I opened two streams there and they don't block, look at the igpu screen...🙂
Thanks again for your patience

apollo I see the error:
2025-03-06 18:02:54.486 webui: Stop streaming /stream/channelid/1146732662?profile=h264-vaapi, muxer reported errors
Usually this happens when the stream has errors. When you use ffmpeg the data is clean? meaning you don't have artifacts on the video/audio? how is the video if you use Kodi with 'pass' profile?
ffmpeg is way more robust than tvh ... when it comes to error handling 🙁 .
You have a lot of margin for GPU processing ... now you should know that most of users are doing the other way around: H264 to HEVC (that is way more computational intensive). Also in your case you don't want to compress the stream to low bitrate (so you are not stressing the algorithm of compression 🙂 ). CQP is one of the lowest computationally rc_mode-s.

Hi,
profile ffmpeg no problem, kodi with profile pass no problem.
H264+vaapi problem with stuttering audio playback for a few seconds then stops...
Thanks

I have a new branch that is removing the disconnect when mux will report error (for testing only).
In order to compile my branch you have to replace:
git clone https://github.com/tvheadend/tvheadend.git
with:
git clone https://github.com/uknunknown/tvheadend.git
git switch dev_remove_err
All the other steps from documentation (up to the point where you install with dpkg should remain the same). Note the name of the file will change.

Let's see if I understand correctly, do I need to follow the steps for Linux on this page?

uknunknown/tvheadend.git

No ... the steps for install are in: https://docs.tvheadend.org/documentation/development/compiling/compiling-tvh-with-vaapi-support/for-lubuntu-24.04
You have to start from Compile tvheadend (somewhere around middle of the page) and replace:
git clone https://github.com/tvheadend/tvheadend.git
with:
git clone https://github.com/uknunknown/tvheadend.git git switch dev_remove_err
Follow the next steps to compile ... up to the point where a new deb file was made.
This is where you use the command to install deb file:
sudo dpkg -i tvheadend_4.3- ********
After you install ... your old settings should be the same like before ... only that you will use the new branch, that I made (with one line commented).

Hi,
I did the clone however the problem remained tried with kodi after a few seconds the playback stops...
Thanks

apollo Can you collect the logs? because how I disabled the first level of protection ... I want to see what is breaking after.

apollo

Thanks

other things re breaking ... 🙁 I think is easier if you could record a 30s to 1 min using 'pass' profile and upload it somewhere where is accessible for download. I will perform more tests on that sample 🙂 .

apollo

Hi,
I hope that's what you wanted

apollo no ... not the log. My goal is to replicate the issue you have on my setup.
For that you need to save (using DVR feature) a video of 30s - 60s with profile 'pass': Configuration / Recording / Digital Video Recording Profiles --> on the right side look for: General Settings / Stream profile = pass.
To start the actual recording you have to go to: Electronic Program Guide ; select one show (anything with blue bar - that is available now) click on the 'i' icon on the left side (new window should open).
At the bottom of that window there is a button Recording ... press on it.
Wait for 30 sec.
Go to Digital Video Recorder / Upcoming Current Recordings ; select the line with the show (you are recording) and press button Stop (red).
"Do you really want .... " --> Yes.
Now select Digital Video Recorder / Finished Recordings you should see that recording. Select that show and press the button Download (above).
Upload the file somewhere ... should be a ts file relative large (could be even 100MB)

apollo

Hi,
I think I did what you asked me to do this time...🙂

ukn_unknown

apollo 🙂 no ... this is a 'link' to the file ... not the recording. The file has to be large ... many MB.
"Now select Digital Video Recorder / Finished Recordings you should see that recording. Select that show and press the button Download (above)."
--> you have to select the recording (left click on it) and press the Download button that is above the selected line (with a green arrow down).

Forgive me...
Thank you

apollo No problem. Received.

apollo bad news 🙁 ... when I loaded the file using ffmpeg from HDD it was able to play it; so I don't know how to repro your problem. Probably I have to find a way to load the file without ffmpeg to repro the problem.

Hi, is it possible to reinstall tvheadend with your settings? Thanks

ukn_unknown

apollo I have to think about this problem.
my settings are:
codec profile

stream profile

ukn_unknown

apollo I was able to load the file without using ffmpeg (I used --tsfile <FILE_PATH>) and it works as expected (is transcoding properly in H264 or HEVC).
In this log you can see I tested pass, h264 and hevc ... all working. There are some warnings ... but I get that on many channels - I don't think is the real reason of your failure.
